What do whales eat?

This dolphin uses echolocation to find food.

This whale gulps down  tons of wate

Whales  are divided in to two  groups: one is toothed whales, the other is baleen whales. Toothed whales eat meat like fish and the killer whale is the only whale that eats marine mammals but only manatees and dugongs eat underwater plants. They  use  echolocation, which helps them find food. They make buzzing sound which spreads thousands of  miles around.  When it hits an object  it bounces of  it and the whale knows the  shape and size of it and  it flips its powerful fluke  and swims through the water as fast  as a race car and caches its  prey. Baleen whales have quite a different way of living, They eat shrimp like animals called krill, plankton, and other small fish. They use their baleen plates to trap the tiny living animals.They take huge gulps of water with all the food. Their tongue pushes out the water and traps tiny fish and they gulp it down.
