What role do blue whales play in their ecosystem?

The blue whales, along with the other great whales, play a key role in maintaining a healthy ocean ecosystem. Through their defecation, whales fertilize the microscopic phytoplankton, upon which all sea life depends.

What is a whales role in the ocean?

Whales play an important role in regulating ocean ecosystems. When whales dive deep in the ocean, they stir up nutrients from the depths below. This action promotes better nutrient circulation, and supports phytoplankton at the surface of the water – a major food source for many fish and crustaceans.

What impact does whales have on the environment?

They play a vital role in the health of the oceans where they help provide up to 50% of our oxygen, combat climate change and sustain fish stocks. The way that whales feed, poo, migrate, and dive between the surface and the ocean depths (known as the ‘whale pump’), circulates essential nutrients throughout the ocean.

What would happen if whales went extinct?

Phytoplankton and the single-celled variety that krill eat are responsible for absorbing a massive amount of carbon from the atmosphere. In the absence of whales, krill would likely eat much of the free-floating phytoplankton on the ocean’s surface, resulting in a marked acceleration in climate change.

What role do blue whales play in their ecosystem? – Related Questions

Why is whales important to humans?

Wherever whales are found, so are phytoplankton. These tiny creatures produce every second breath we take, by contributing to at least 50 per cent of all the oxygen in our atmosphere. They also capture about 37 billion tonnes of carbon dioxide or four Amazon forests’ worth.

Why is it important to save whales?

Whales play an amazing role in an ecosystem that keeps every creature on Earth alive, including you! Whales play a vital role in the marine ecosystem where they help provide at least half of the oxygen you breathe, combat climate change, and sustain fish stocks.

Will whales go extinct?

Right whales are declining so quickly that they may be functionally extinct by 2040 if more isn’t done to save them.

What will happen if blue whales went extinct?

Humans selectively fish out the largest species from Earth’s oceans, causing their populations to dwindle. If that weren’t alarming enough, the extinction of those animals—think great white shark, bluefin tuna, and blue whale—could ripple down the food chain and spell extinction for entire ecosystems.

What would happen if all humans went extinct?

If every human disappeared, homes would decay, animals would fend for themselves, and cities would revert back to nature. There would be no more pollution or hunting, but also no more farms or pets. Scientists would be able to find evidence of humans after 15-20,000 years.

Do whales clean the ocean?

Whale excrement fertilizes the ocean, producing large phytoplankton blooms that absorb enormous amounts of carbon dioxide. Scientists point out that helping whale populations recover from past overharvesting can help reduce greenhouse gas levels in the atmosphere.

Can whales save the planet?

The way that whales feed, poo, migrate, and dive between the surface and the ocean depths (known as the ‘whale pump’), circulates essential nutrients throughout the ocean. This in turn supports healthy marine ecosystems and the growth of phytoplankton, which locks in a massive amount of carbon from the atmosphere.

Why does whale poo matter?

Whale poop is important not just to scientists, but to the ocean, too. It’s rich in iron, which is an important micronutrient for ocean creatures. Teeny marine plants called phytoplankton eat the iron, tiny shrimp-like krill eat the plants, and whales and fish eat the krill, which in turn produces yet more poop.

What are 3 facts about whales?

Top 10 facts about whales
  • Whales are divided into two main groups.
  • Humpback whales don’t eat for most of the year.
  • All toothed whales have a ‘melon’ in their foreheads.
  • Some whales bubble net feed.
  • There used to be thousands of blue whales.
  • Whales are often caught in nets.

What cool things can whales do?

Whales can hold their breath for at least 20 minutes. On average, whales can remain submerged for 20 minutes. Sperm whales have the most efficient respiratory system, allowing them to spend up to 90 minutes underwater. A Cuvier’s beaked whale holds the record of longest stay underwater by a mammal.

What is a group of whales called?

A group of whales is commonly referred to as a pod, among other names. Like humans, whales form groups and families through friendship or for other biological reasons. A group such as this may also be called a school or gam.

What is unique about a whale?

Whales are the largest animals to have ever lived – even larger than any dinosaur! Blue whales are the largest animals on the planet; they are as long as three back-to-back school buses and have a heart the size of a small car.

What kind of oil comes from whales?

whale oil, also called train oil, any oil derived from any species of whale, including sperm oil from sperm whales, train oil from baleen whales, and melon oil from small toothed whales. From the 16th century through the 19th century, whale oil was used principally as lamp fuel and for producing soap.

Do whales sleep?

All whales and dolphins sleep, but different species have different methods and requirements for sleep and rest. The length of sleep can vary massively between species. There are some common methods and positions for sleeping.

How smart is a whale?

However, we do know that whales are very smart. Like dolphins, whales are excellent communicators, and they show high levels of emotional and social intelligence. They also have very large brains, actually some of the largest.

Do whales feel pain?

Whales can feel pain, fear and distress. Animals that have this ability are called ‘sentient’. Did you know? At 16,000km, humpback whales undertake the longest annual migration of any mammal from their cold water feeling grounds to warmer tropical waters to breed and give birth.

What animal is smarter than humans?
