What does a toothed whale eat?
Toothed Whales feed largely feed on fish and squid, but a few, like certain eco-types of killer whales, feed on marine mammals. Echolocation is a prominent sense in toothed whales. It is a type of sonar that the animals rely on to help build up a picture of their surroundings.
Why do baleen whales eat krill?
One of the main constraints to eating, for baleen whales, is to open their mouths wide enough to swallow massive amounts of krill-containing water. It’s more energetically advantageous for these toothed predators to be medium size and eat medium size prey, than to dive long and deep searching for an elusive large meal.
How many whales eat krill?
Blue whales, the largest animal on Earth, can hold 90 metric tons of water and prey in a single lunge, allowing the whale to consume an estimated 3.6 metric tons of krill or 40 million individuals every day.
Do baleen whales eat other whales?
They feed on fish and squid like other toothed whale species, but will also target seals, sea birds and even other whale species – even if they are far bigger than themselves. Killer whales are also the only known predator of great white sharks.
How much krill does a whale eat a day?
Blue whales eat krill – tiny, shrimp-like crustaceans that live throughout Earth’s oceans. The huge whales can eat up to four tonnes of krill every day.
What do toothed whales eat in the ocean?
The toothed whales have teeth that they use to hunt and eat, and the baleen whales have beards in place of teeth. That makes the diet of each one different. At least in the size of their prey. These are the bristles in the mouth that help the whales to trap small fish, krill and plankton. What do the Baleen Whales feed on?
How much krill does a baleen whale eat?
Scientists estimate that large baleen whales eat about 4% of their body weight each day during the feeding season. Food intake during the feeding season exceeds daily requirements, and excess energy is stored as fat, much of it in the blubber. A blue whale eats up to 3,600 kg (8,000 lbs.) of krill each day for about 120 days.
What’s the difference between toothed whales and baleen whales?
These are: toothed whales and baleen whales. The name itself already gives an idea what it refers to. The toothed whales have teeth that they use to hunt and eat, and the baleen whales have beards in place of teeth. That makes the diet of each one different. At least in the size of their prey.
How does a baleen whale move its food?
A baleen whale probably uses its huge tongue for moving food trapped inside the baleen, for squeezing water out of the mouth, and for swallowing.

How are whales able to filter their food?
This mammals use a filter-feeder system inside the mouths. The baleen system works by a whale opening its mouth underwater and taking in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as food source for the whale.
