Coronavirus disease 2019

COVID-19 is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic.

The symptoms of COVID‑19 can vary but often include fever,[7] fatigue, cough, breathing difficulties, loss of smell, and loss of taste.[8][9][10] Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.[11][12] Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction).[13] Older people have a higher risk of developing severe symptoms. Some complications result in death. Some people continue to experience a range of effects (long COVID) for months or years after infection, and damage to organs has been observed.[14] Multi-year studies on the long-term effects are ongoing.[15]

COVID‑19 transmission occurs when infectious particles are breathed in or come into contact with the eyes, nose, or mouth. The risk is highest when people are in close proximity, but small airborne particles containing the virus can remain suspended in the air and travel over longer distances, particularly indoors. Transmission can also occur when people touch their eyes, nose, or mouth after touching surfaces or objects that have been contaminated by the virus. People remain contagious for up to 20 days and can spread the virus even if they do not develop symptoms.[16]

Testing methods for COVID-19 to detect the virus’s nucleic acid include real-time reverse transcription polymerase chain reaction (RT‑PCR),[17][18] transcription-mediated amplification,[17][18][19] and reverse transcription loop-mediated isothermal amplification (RT‑LAMP)[17][18] from a nasopharyngeal swab.[20]

Several COVID-19 vaccines have been approved and distributed in various countries, many of which have initiated mass vaccination campaigns. Other preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, use of face masks or coverings in public, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face. While drugs have been developed to inhibit the virus, the primary treatment is still symptomatic, managing the disease through supportive care, isolation, and experimental measures.

Andreessen Horowitz a16z Fuels AI and Biotech Innovations with Strategic Investments

Tech leaders respond to the rapid rise of DeepSeek

All these indicate the commitment a16z has in shaping the future of technology and healthcare through strategic investments. Both platforms use Stability AI’s models to bring creators’ visions to life and Story’s blockchain technology to enable provenance and attribution throughout the creative process. These real-world applications highlight how creators can safeguard their intellectual property while thriving in a shared creative economy. Raspberry AI offers brands and manufacturing creative teams technology solutions, which can help accelerate each stage of the fashion product development cycle to increase speed to market and profitability while reducing costs. Andreessen Horowitz, or a16z, is one of the leading AI investors and targets only innovative startups. They participated in the round that funded Anysphere on January 14, 2025, with a total sum of $105 million for an AI coding tool known as Cursor, whose valuation has reached $2.5 billion.

The startup was co-founded by Chief Executive Officer and serial entrepreneur Munjal Shah and a group of physicians, hospital administrators, healthcare professionals and AI researchers from organizations including El Camino Health LLC, Johns Hopkins University, Stanford University, Microsoft Corp., Google and Nvidia Corp. PIP Labs, an initial core contributor to the Story Network, is backed by investors including a16z crypto, Endeavor, and Polychain. Co-founded by a serial entrepreneur with a $440M exit and DeepMind’s youngest PM, PIP Labs boasts a veteran founding executive team with expertise in consumer tech, generative AI, and Web3 infrastructure. The startup has also created other AI agents for tasks like pre- and post-surgery wound care, extreme heat wave preparation, home health checks, diabetes screening and education, and many more besides. The startup said its AI Agent creators include Dr. Vanessa Dorismond MD, MA, MAS, a distinguished obstetrician and gynecologist at El Camino Women’s Medical Group and Teal Health, who helped to create an AI agent that’s focused on cervical cancer check-ins and enhancing patient education. According to the startup, the objective of these AI agents is to try and solve the massive shortage of trained nurses, social workers and nutritionists in the healthcare industry, both in the U.S. and globally.

How Global Brands Use Geo-Targeting To Increase Conversions; Interview With The CMO Of Geo Targetly

Holger Mueller of Constellation Research Inc. said Hippocratic AI is bringing two of the leading technology trends to the healthcare industry, namely no-code or low-code software development and AI agents. The launch is a bold step forward in healthcare innovation, giving clinicians the opportunity to participate in the design of AI agents that can address various aspects of patient care. It says clinicians can create an AI agent prototype that specializes in their area of focus in less than 30 minutes, and around three to four hours to develop one that can be tested. Shah said the last nine months since the company’s previous $50 million funding round have seen it make tremendous progress. During that time, it has received its first U.S. patents, fully evaluated and verified the safety of its first AI healthcare agents, and signed contracts with 23 health systems, payers and pharma clients.
- Holger Mueller of Constellation Research Inc. said Hippocratic AI is bringing two of the leading technology trends to the healthcare industry, namely no-code or low-code software development and AI agents.
- Those investments highlight the commitment of the group to using AI to address important issues and are also focusing on how AI can improve different industries, including healthcare and consumer services.
- But with U.S. companies raising and/or spending record sums on new AI infrastructure that many experts have noted depreciate rapidly (due to hardware/chip and software advancements), the question remains which vision of the future will win out in the end to become the dominant AI provider for the world.
In order to ensure its AI agents can do their jobs safely, Hippocratic AI says it only works with licensed clinicians to develop them, taking steps to verify their qualifications and experience first. Once clinicians have built their agents, they’ll be submitted to the startup for an initial round of testing. Through the Hippocratic AI Agent App Store, healthcare organizations and hospitals will be able to access a range of specialized AI agents for different aspects of medical care.

Your vote of support is important to us and it helps us keep the content FREE.

By incorporating this wisdom into its AI agents, it’s making them safer and improving patient outcomes, it said. Crucially, any agent created using its platform will undergo extensive safety training by both the creator and Hippocratic AI’s own staff. Every clinician will have access to a dashboard to track their AI agent’s performance and use and receive feedback for further development.

Meanwhile, Kristina Dulaney, RN, PMH-C, the founder of Cherished Mom, an organization dedicated to solving maternal mental health challenges, helped to create an AI agent that’s focused on helping new mothers navigate such problems with postpartum mental health assessments and depression screening. The startup was initially focused on creating generative AI chatbots to support clinicians and other healthcare professionals, but has since switched its focus to patients themselves. Its most advanced models take advantage of the latest developments in AI agents, which are a form of AI that can perform more complex tasks while working unsupervised. Despite rapid advancements in AI, creators in open-source ecosystems face significant challenges in monetizing derivative works and securing proper attribution.

Once the AI agent is up and running, the clinicians who created it will be able to claim a share of the revenue it generates from the startup’s customers. Currently the technology is being used by Under Armour, MCM Worldwide, Gruppo Teddy and Li & Fung to create and iterate apparel, footwear and accessories styles. The company’s existing investors Greycroft, Correlation Ventures and MVP Ventures also joined in the round, along with notable angel investors, including Gokul Rajaram and Ken Pilot. Clearly, even as he espouses a commitment to open source AI, Zuck is not convinced that DeepSeek’s approach of optimizing for efficiency while leveraging far fewer GPUs than major labs is the right one for Meta, or for the future of AI.

Story aims to bridge this gap by combining Stability AI’s cutting-edge technology with blockchain’s ability to secure digital property rights. For example, creators could register unique styles or voices as intellectual property on Story with transparent usage terms. This would enable others to train and fine-tune AI models using this IP, ensuring that all contributors in the creative chain benefit when outputs are monetized.

Story, the global intellectual property blockchain, has announced its integration with Stability AI’s state-of-the-art models to revolutionize open-source AI development. This collaboration enables creators, developers, and artists to capture the value they contribute to the AI ecosystem by leveraging blockchain technology to ensure proper attribution, tracking, and monetization of creative works generated through AI. Andreessen Horowitz, or a16z, is investing in AI and biotech to lead the way in innovation.

The same day, a16z also led a Series A investment in Slingshot AI, which has raised a total of $40 million to create a foundation model for psychology. Those investments highlight the commitment of the group to using AI to address important issues and are also focusing on how AI can improve different industries, including healthcare and consumer services. In general, a16z is committed to supporting AI innovations that could have a profound impact on society. We are thrilled to see our models used in Story’s blockchain technology to ensure proper attribution and reward contributors,” said Scott Trowbridge, Vice President of Stability AI. Others include Kacie Spencer, DNP, RN, the chief nursing officer at Adtalem Global Education Inc., who has more than 20 years of experience in emergency nursing and clinical education. Her AI agent is focused on patient education for the proper installation of child car seats.

Story is the world’s intellectual property blockchain, transforming IP into networks that transcend mediums and platforms, unleashing global creativity and liquidity. By integrating Stability AI’s advanced models, Story is taking a significant step toward building a fair and sustainable internet for creators and developers in the age of generative AI. Hippocratic AI said it’s necessary to have clinicians onboard because they have, over the course of their careers, developed deep expertise in their respective fields, as well as the practical insights to help cure specific medical conditions and the clinical workflows involved.

In a statement, Raspberry AI said the funding would be used to accelerate its product development and add top engineering, sales and marketing talent to its team. But with U.S. companies raising and/or spending record sums on new AI infrastructure that many experts have noted depreciate rapidly (due to hardware/chip and software advancements), the question remains which vision of the future will win out in the end to become the dominant AI provider for the world. Or maybe it will always be a multiplicity of models each with a smaller market share? That’s followed by more extensive evaluations and safety assessments by an extensive network of more than 6,000 nurses and 300 doctors, who will confirm that it passes all required safety tests.

Andreessen Horowitz (a16z) Fuels AI and Biotech Innovations with Strategic Investments

For instance, one of its AI agents is specialized in chronic care management, medication checks and post-discharge follow-up regarding specific conditions such as kidney failure and congestive heart failure. The healthcare-focused artificial intelligence startup Hippocratic AI Inc. said today it has closed on a $141 million Series B funding round that brings its total amount raised to more than $278 million. “This round of financing will accelerate the development and deployment of the Hippocratic generative AI-driven super staffing and continue our quest to make healthcare abundance a reality,” he promised. Raspberry AI, the generative AI platform for fashion creatives, has secured 24 million US dollars in Series A funding led by Andreessen Horowitz (a16z). Today, we’re going in-depth on blockchain innovation with Robert Roose, an entrepreneur who’s on a mission to fix today’s broken monetary system.

Индексы Форекс: раскрой секреты валютного рынка!
Форекс индексы: Трейдинг для продвинутых! Узнай, как заработать!

Есть тиковые графики Форекс, графики баров, «японские свечи», эквиобъемные графики и другие.

Практическое Применение Индексов в Торговле на Форекс

Управление капиталом Forex — это профессиональный подход и минимум усилий в вопросах получения прибыли. Каждый трейдер выбирает наиболее подходящий и удобный способ наблюдения за значением Forex индексов, пользуясь различными графиками. В США сегодня выходят данные по личным доходам и расходам, а также ценовой индекс потребительских расходов за август. Ждем также индекс потребительского доверия Университета Мичигана за сентябрь.

Основы фондовых индексов
- Понимание их работы и взаимосвязи с валютными рынками может значительно улучшить ваши торговые стратегии.
- Если два актива имеют положительную корреляцию, то они обычно движутся в одном направлении.
- Прорыв этих уровней может сигнализировать о значительном изменении тренда, что может быть использовано для открытия сделок.
- Использование инструментов технического анализа совместно с фундаментальным анализом, основанным на индексах, может повысить точность прогнозов.
- Поэтому важно использовать кредитное плечо с осторожностью и не рисковать больше, чем вы можете себе позволить потерять.
Это упрощенный пример, но он показывает, как происходит расчет значения индекса на Форексе. В обсуждениях https://forexby.com/ Вы найдете подробности об инвестициях в Форекс — доверительном управлении forex-активами и работе на Форекс бирже. Тем, кто ищет честный способ заработка и приумножения капитала, однозначно стоит попробовать трейдинг. Активно используется в стратегии «Купи и держи» («Buy & Hold»), когда контракт приобретается и удерживается в течение нескольких лет. Стратегия подвержена рискам во времена кризиса, но в благоприятные периоды времени обладает хорошим потенциалом дохода. Значение индексов на графиках Форекс можно отследить, пользуясь линейным режимом (в таком случае графики Форекс называются линейными).

Индекс на Форексе – это показатель, который отражает среднюю стоимость определенной группы валют по отношению к другой валюте или валютной корзине. Он является своего рода барометром, показывающим общее направление движения цен на форекс индексы выбранные валюты. В отличие от торговли отдельными валютными парами, торговля индексами позволяет трейдерам получать выгоду от общих тенденций на рынке, а не от колебаний конкретных валют. Это может быть особенно полезно в периоды высокой волатильности или неопределенности, когда сложно прогнозировать движение отдельных валютных пар. Сравнительный анализ этих индексов позволяет трейдерам лучше понять глобальные экономические тренды и их влияние на валютные пары.

Важно постоянно мониторить динамику корреляции и адаптировать свою стратегию. Индексы могут стать мощным инструментом в арсенале Форекс-трейдера, позволяющим прогнозировать движение валютных пар. Однако, необходимо понимать, что индексы – это лишь один из факторов, влияющих на рынок, и нельзя полагаться на них исключительно. Эффективное использование индексов в торговле требует разработки грамотных стратегий и тактик. Наконец, помните, что торговля на финансовых рынках, включая фондовые индексы Форекс, сопряжена с рисками, и что прошлые результаты не гарантируют будущей прибыли.

Экономический и новостной календарь в трейдинге опционами стоит ли использовать?
Экономический и новостной календарь в трейдинге опционами

Стоит ли доверять информации из календаря, выстраивать стратегию торговли только на основании полученных данных? Чтобы извлекать максимум полезных данных из экономических новостей, трейдеру нужно научиться правильно пользоваться информацией, опираться на нее исключительно для диверсифицированная рисков. В комбинации со вспомогательными инструментами календарь новостной календарь работает более эффективно.

форекс новостного календаря

Он предоставляет трейдерам необходимую информацию для принятия обоснованных решений. Понимание влияния экономических новостей и умение адаптировать свою стратегию к изменяющимся рыночным условиям. Регулярный анализ новостного календаря позволит вам оставаться в курсе событий и действовать на опережение. Для начинающего трейдера или инвестора необходимо обращать пристальное внимание на данные, которые публикуются в экономическом календаре.
- И наоборот, если денег в обращении недостаточно, а центральный банк стремится стимулировать экономику, он снижает процентные ставки, удешевляя стоимость денег для бизнеса и частных лиц.
- Прежде, чем принимать решение о начале торговли на валютном рынке, внимательно продумайте инвестиционные цели, оцените ваш уровень опыта и степень азартности.
- Честный брокер всегда предлагает своим клиентам реальные условия, которые, тем не менее, остаются выгодными.
- Поэтому более высокие запасы должны привести к снижению цен на нефть.
- Отчет института управления поставками (ISM) измеряет поток новых заказов, таким образом прогнозируя производственную активность в экономике.
Важность событий

Помимо своей уникальной значимости для фундаментального анализа и прогнозирования, как уже было сказано выше, экономический календарь служит неплохим индикатором для торговли по новостям на рынке Форекс. Если Вы торгуете на бирже и часто нуждаетесь в опорных данных для открытия новых ордеров, то календарь может служить надежным источником информации. Индекс цен на сырьевые товары отслеживает среднее изменение цен на такие товары, как нефть, минералы и металлы. Это особенно важно для валют стран-экспортеров товаров, таких как Канада и Австралия. Увеличение индекса будет означать рост цен и, следовательно, более высокую прибыль от экспорта.

Экономические новости, которые постоянно публикуются, оказывают прямое влияние на финансовые рынки. При торговле валютными парами на форекс следует учитывать, что валютная пара фактически представлена двумя разными экономиками. Использование новостного календаря Форекс – это важный элемент успешной торговли на https://forexby.com/ валютном рынке.

Сразу после появления новости трейдер может анализировать фактические показатели. Важно, чтобы они соответствовали или были максимально приближены к прогнозируемым, тогда актив поднимется в цене. Задача трейдера — сделать правильные выводы и принять решение о покупке или продаже. Реакция рынка сильно зависит от разницы между фактическими и прогнозируемыми показателями.

Отчет института управления поставками (ISM) измеряет поток новых заказов, таким образом прогнозируя производственную активность в экономике. Показание ниже 50 означает, что количество производственных заказов сократилось по сравнению с предыдущим периодом. Поскольку предложение следует за спросом, увеличение индекса ISM указывает на то, что спрос на товары и услуги увеличился, что является хорошим признаком для экономики. Инфляция является одним из наиболее важных фундаментальных индикаторов, поскольку она показывает, насколько здорова экономика. Страны с развитой экономикой устанавливают свои цели в инфляции на уровне 2%, тогда как в развивающихся странах инфляция может достигнуть 7%, не вызывая при этом паники среди инвесторов.

Экономический календарь как инструмент

Коммерческие кредитные ставки идут рука об руку с процентными ставками центрального банка, поскольку частные банки не могут выдавать кредиты дешевле, чем они их получают. Большинство трейдеров настраивают календарь на основании собственных фильтров, основываясь регионах, классах активов и валют, которыми они торгуют. Аналитика и прогнозы — это основные факторы, на которые должен ориентироваться трейдер при принятии торговых решений. Прогнозы можно составлять самостоятельно, на основе новостей, а можно знакомиться с готовыми экспертными оценками того или иного факта. Если самостоятельная торговля кажется трейдеру слишком обременительной, он может воспользоваться услугой «доверительное управление капиталом».

Что такое пипс pip и пункт pipette в Форекс-трейдинге?
Лот Lot на Форекс: Что такое и как его рассчитать?

Или если валютная пара USD/JPY изменилась в цене с 119,14 до 119,10, говорят, что она понизилась на 4 пункта. Таким образом, значение пункта напрямую влияет на прибыльность трейдера. Чем больше пункт, тем больше прибыль может получить трейдер при одинаковом объеме 1 пункт в трейдинге сделки и одинаковом изменении цены.
- • Опытные трейдеры могут использовать стандартные лоты, так как они лучше понимают механизмы рынка и готовы рисковать большими суммами.
- Пункты указывают на изменение котировки и стоимость рыночной позиции, которую можно открыть.
- Затем вы можете умножить эту сумму на общую сумму вашей транзакции.
- Если переводить в числовое значение один пипс будет равен 0,00001 против 0,0001 у пункта.
- На представленном скриншоте сделан расчет 0,1 лота для пары EUR/USD.
Расчет стоимости одного пункта

Чтобы рассчитать прибыль в дoллapax CШA, необходимо умножить кoличecтвo зapaбoтaнныx пунктов нa цeну 1 пункта для вaлюты, пpибыль пo кoтopoй вы зapaбoтaли. Хоть в случае с большинством активов пипс — это четвертая цифра после запятой, это правило работает далеко не для всех акций, поэтому важно понимать принцип действия системы подсчета. Также пункты в трейдинге являются вспомогательным инструментом для упрощенного описания изменения цен. Они позволяют максимально точно определить разницу между котировками и помогают в коммуникации между брокерами, представителям СМИ.

Пипсы и пункты в трейдинге — в чем отличие? Формулы для расчета 1 pips и points

Пипс pips), или тот же поинт (point) – это один пункт на валютном рынке. То есть минимальный шаг изменения цены валютного курса по направлению понижения или повышения. График любого тренда пары валют или отдельной валюты, наглядно показывает минимальные пункты ее изменения. Некоторые форекс-брокеры выходят за рамки обычных десятичных точек «4 и 2», котируя пары с повышенной точностью до десятичной точки «5 и 3». Эта дополнительная точность предполагает указание дробных пунктов, которые также называются «пунктами» или «пипетсами».

Калькулятор трейдера на Форекс

Однако существуют еще более простой альтернативный метод вычисления пунктов, который не требует даже покидать сайт брокерской компании, с которой вы привыкли торговать. Такой удобный инструмент для инвесторов присутствует на площадке каждого серьезного финансового брокера. С его помощью трейдер может рассчитать цену пункта, шаг цены, размер кредитного плеча и еще множество важных показателей выбранной валютной пары. Любой начинающий трейдер может воспользоваться калькулятором на сайте брокера. Возможная прибыль покажется новичку очень легким способом заработка.

Исходя из того, в какой валюте трейдер держит свой торговый капитал, эти значения будут сконвертированы исходя из текущего курса. Если https://forexby.com/ увеличить объем до 0,1, стоимость 1 пипса также возрастет в 10 раз – с $0,01 до $0,1. Тогда такое же движение в 50 пипсов сможет принести трейдеру уже $5.

Стоимость одного пункта на Форекс

В большинстве валютных пар это число отображается с четырьмя десятичными знаками. Когда пара EUR / USD повышается с 1,1210 до 1,1211, валютная пара повышается на один пункт. И пипсы, и пункты используются для измерения минимального изменения цены.

Android The World Most Popular Mobile Operating System (2)

Android: The World’s Most Popular Mobile Operating System

Android is an open-source mobile operating system developed by Google. Since its official launch in 2008, Android has grown into the most widely used operating system for smartphones, tablets, smart TVs, wearables, and a wide range of connected devices. Its flexibility, customization options, and vast app ecosystem have made it a global standard in mobile technology.

The Origin and Development of Android

Android was originally created by Android Inc., a small startup founded in 2003. Google acquired the company in 2005 and transformed Android into a powerful platform designed to compete in the emerging smartphone market. The first commercial Android device, the HTC Dream, was released in 2008. Since then, Android has evolved through regular versions, each introducing performance improvements, new features, and enhanced security.

Open-Source Philosophy

One of Android’s key strengths is its open-source nature. The Android Open Source Project (AOSP) allows manufacturers and developers to modify and adapt the system to their own needs. This approach has led to a huge variety of devices—from budget smartphones to premium flagship models—running on Android. It also encourages innovation and competition among hardware manufacturers.

Customization and User Experience

Android is known for its high level of customization. Users can personalize their devices with widgets, themes, launchers, and custom layouts. Notifications are flexible and interactive, allowing quick responses and actions directly from the notification panel. Android also supports deep system-level customization, which appeals to advanced users and developers.

The Android App Ecosystem

The Google Play Store hosts millions of applications covering productivity, entertainment, education, health, and gaming. Android apps are primarily built using Java or Kotlin and supported by powerful development tools such as Android Studio. The platform also allows third-party app stores and direct app installations, making software distribution highly flexible.

Security and Updates

Android includes multiple layers of security, such as app sandboxing, permission controls, encryption, and Google Play Protect. Over time, Google has significantly improved update delivery, especially with features like modular system updates and monthly security patches. Many manufacturers now provide longer support periods for their devices.

Android Beyond Smartphones

Android is not limited to phones. Android TV powers smart televisions, Wear OS supports smartwatches, and Android Auto integrates smartphones with car infotainment systems. The same ecosystem extends to tablets, foldable devices, and even IoT solutions, making Android a unified platform across many device categories.

Whales: Giants of the Ocean

Whales: Giants of the Ocean

Whales are among the largest and most remarkable animals on Earth. These marine mammals live in oceans around the world, from warm tropical waters to the cold seas surrounding the poles.

Life Beneath the Surface

Although whales spend their lives in water, they breathe air through blowholes located on top of their heads. They must regularly return to the surface to breathe before diving again in search of food or traveling through the ocean.

Whales are warm-blooded, give birth to live young, and nurse their calves with milk. A thick layer of fat called blubber helps protect them from cold water and stores energy during long migrations.

Two Main Groups

Whales are generally divided into baleen whales and toothed whales. Baleen whales filter small animals from the water using flexible plates inside their mouths. This group includes blue whales, humpback whales, and gray whales.

Toothed whales use teeth to catch fish, squid, and other prey. Many of them also use echolocation, producing sounds and listening for returning echoes to understand their surroundings. Sperm whales, belugas, and orcas belong to this group.

The Blue Whale

The blue whale is the largest known animal to have ever lived. An adult can grow longer than a city bus and weigh well over one hundred tonnes. Despite its enormous size, it feeds mainly on tiny crustaceans called krill.

Communication and Migration

Whales communicate using clicks, whistles, pulses, and complex songs. Some sounds can travel across great distances underwater. Humpback whales are especially famous for their long, patterned songs.

Many species migrate thousands of kilometres each year. They often feed in cold, nutrient-rich waters before traveling to warmer regions where they mate and give birth.

Protecting Whales

Commercial hunting once caused severe declines in many whale populations. Today, whales also face threats from fishing gear, ship collisions, underwater noise, pollution, and changes to ocean ecosystems.

Conservation programs, safer fishing practices, protected habitats, and international cooperation can help whale populations recover. Protecting whales also supports healthier oceans because these animals play an important role in marine food webs and nutrient cycles.

Many species migrate thousands of kilometres each year. They often feed in cold, nutrient-rich waters before traveling to warmer regions where they mate and give birth.

Protecting Whales

Commercial hunting once caused severe declines in many whale populations. Today, whales also face threats from fishing gear, ship collisions, underwater noise, pollution, and changes to ocean ecosystems.

Conservation programs, safer fishing practices, protected habitats, and international cooperation can help whale populations recover. Protecting whales also supports healthier oceans because these animals play an important role in marine food webs and nutrient cycles.

Whales: Giants of the Ocean

Whales: Giants of the Ocean

Whales are among the largest and most remarkable animals on Earth. These marine mammals live in oceans around the world, from warm tropical waters to the cold seas surrounding the poles.

Life Beneath the Surface

Although whales spend their lives in water, they breathe air through blowholes located on top of their heads. They must regularly return to the surface to breathe before diving again in search of food or traveling through the ocean.

Whales are warm-blooded, give birth to live young, and nurse their calves with milk. A thick layer of fat called blubber helps protect them from cold water and stores energy during long migrations.

Two Main Groups

Whales are generally divided into baleen whales and toothed whales. Baleen whales filter small animals from the water using flexible plates inside their mouths. This group includes blue whales, humpback whales, and gray whales.

Toothed whales use teeth to catch fish, squid, and other prey. Many of them also use echolocation, producing sounds and listening for returning echoes to understand their surroundings. Sperm whales, belugas, and orcas belong to this group.

The Blue Whale

The blue whale is the largest known animal to have ever lived. An adult can grow longer than a city bus and weigh well over one hundred tonnes. Despite its enormous size, it feeds mainly on tiny crustaceans called krill.
