What do whales filter plankton through?

Asked by: Vanessa Cruz

baleen platesbristly baleen plates filter, sift, sieve or trap the whales’ favourite prey from seawater inside their mouths.

How do whales filter water?

Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale.

How do whales filter out food?

Gray whales, a family of baleen whales, are bottom feeders. They suck sediment and small benthic crustaceans called amphipods from the sea floor. To do this, they slowly swim on their sides and filter their food through their baleen plates.

What do whales use to filter out zooplankton?

Baleen whales typically seek out a concentration of zooplankton, swim through it, either open-mouthed or gulping, and filter the prey from the water using their baleens.

How do whales catch plankton?

Water–and zooplankton–enter a right whale’s mouth through a gap in the front baleen plates. Zooplankton is caught in the finely fringed baleen mat; water flows through the baleen and out the sides of the mouth.

How do whales filter out salt water?

Kidneys Built for the Job
The salt content in whales’ blood and other body fluids is about one-third as salty as sea water, similar to that of other mammals. That means when the whale drinks salt water, her kidneys must get rid of all that excess salt. The whale’s kidneys are built for this job.

How do blue whales filter water?

Blue whales are filter-feeders, using baleen plates in the mouth made of keratin, also found in people’s fingernails, to strain krill from ocean water.

Why whales are called filter feeders?

Whales called as filter feeders because they used to filtered their food through baleen plates. they suction water into their mouths at high velocities while their body remains stationary. The food along with water moves through the filtering pads or baleen plates that covered the entrance of their throat.

Are whales filter feeders?

Baleen whales are filter-feeders, but they’re not passive grazers of whatever drifts by like they’re hundred ton barnacles. Some baleen whales skim concentrations of plankton near the surface, and many are active and efficient predators of schooling marine organisms.

How do whale sharks eat plankton?

Although its mouth can stretch to four feet wide, a whale shark’s teeth are so tiny that they can only eat small shrimp, fish and plankton by using their gill rakers as a suction filter.

How do blue whales eat plankton?

By eating, digesting, and disposing of krill, whales take iron from deep in the ocean and bring it to the surface with their floating feces, making it usable for tiny phytoplankton, krill’s main prey. More feces creates a positive feedback loop as more phytoplankton means more krill, which can support more whales.

How do whales feed?

Baleen whales feed by filtering or straining food from the water. They love to eat krill, fish, zooplankton, phytoplankton, and algae. Some, such as the right whale, are called “skimmers”. These whales swim slowly with their huge mouths open to take in large amounts of water and food.

How do whales eat without swallowing water?

In a dramatic display, the animals open their jaws nearly 90 degrees and gulp a mouthful of ocean water. Then, they push the water out of their mouth as their throat pouch deflates, trapping tiny fish and krill in their baleen.

How do whales spit out water?

As whales reach the water surface to breathe, they forcefully expel air through the blowhole. The exhalation is released into the comparably lower-pressure, colder atmosphere, and any water vapor condenses.

How do whales keep water out of their lungs?

After each breath, the blowhole is sealed tightly by strong muscles that surround it, so that water cannot get into the whale or dolphin’s lungs.
