How do blue whales feed?

Blue whales are the largest animals ever to live on our planet. They feed almost exclusively on krill straining huge volumes of ocean water through their baleen plates (which hang from the roof of the mouth and work like a sieve). Some of the biggest individuals may eat up to 6 tons of krill a day.

How do whales produce phytoplankton?

In death whales carry the tons of carbon stored in their massive bodies down to rest on the seafloor where it can remain for centuries. Whale excrement fertilizes the ocean producing large phytoplankton blooms that absorb enormous amounts of carbon dioxide.

What do krill feed on?

phytoplanktonAntarctic krill are filter feeders that eat tiny phytoplankton (pelagic algae). They use their small hair-like legs to filter out these microscopic algae that bloom in the nutrient-rich waters around Antarctica. These blooms are densest at the ice edge so Antarctic krill are often also densest near that system.

Why do whales consume plankton?

Food webs are often pretty short which confused many scientists for a long time. Ever wonder why such a large whale feeds on such small planktonic organisms such as krill? … However the primary means for determining what marine organisms eat is to study their stomach contents which is exactly what Reilly et al.

How do whales eat krill?

In fact krill – about two inches long –make up the majority of their diet. Blue and humpback and other baleen whales are filter feeders. They take in huge gulps of seawater dense with krill straining out the water though their baleen and then swallowing their catch.

How do blue whales survive on plankton?

In a nutshell whales some of the largest creatures on the planet can survive by eating krill because they eat so many of them.

How do whales act as carbon sinks?

Whales accumulate carbon in their bodies during their long lives. When they die they sink to the bottom of the ocean each great whale sequesters 33 tons of CO2 on average taking that carbon out of the atmosphere for centuries. A tree meanwhile absorbs only up to 48 pounds of CO2 a year.

Can a whale swallow a human?

Whales in general are not capable of swallowing a human being and therefore will not eat you. However there is a species of whales that does pose a legitimate challenge to that general theory: sperm whales. See also what is the importance of estuaries

How do whales eat without swallowing water?

Marine mammals feed entirely underwater. Seals and dolphins can hunt catch and swallow food beneath the water. Marine mammals make sure that they capture their prey and not swim away before swallowing. They do this by sucking the food deeper into the mouth by pulling back their tongue once the prey is in their mouth.

How do whales impact the biosphere?

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 do whales feed on krill?

This range seems to reflect the energy density of the food—whales need to eat more krill to get the same energy as they would from a smaller amount of fish. “As large baleen whales get bigger the anatomical machinery that allows them to eat also gets relatively bigger ” Goldbogen said.

Half a million calories in a mouthful – filter feeding

What do whales provide for plankton?

Because whales can’t “poop” under pressure they take their bathroom breaks at the ocean’s surface and by doing so supply phytoplankton with life giving nutrients like iron nitrogen and phosphorus. Whales are the ocean’s gardeners tending the forest of phytoplankton on which we all depend.

How do whales help produce oxygen?

Whales accumulate carbon in their bodies during their long lives some of which stretch to 200 years. … 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.

How do Humpbacks feed?

Humpback whales filter-feed on small crustaceans (mostly krill) and small fish. They use several techniques to help them herd corral and disorient prey and that can include using bubbles sounds the seafloor and even their pectoral fins.

How do whales filter plankton?

All baleen whales have baleen instead of teeth which they use to collect shrimp-like krill plankton and small fish from the sea. These bristly baleen plates filter sift sieve or trap the whales’ favourite prey from seawater inside their mouths.

Do men have breasts?

How Does A Whale Feed On Zooplankton?

A right whale “grazes” by swimming slowly through swarms of small zooplankton (animal plankton) with its mouth open.

Are Whale sperm bigger than human sperm?

Amazing whales have some of the smallest sperm of all mammals. They vary from 50-75 microns whereas human sperm are 40-90 microns long.
