What food do whales eat?

it really Depends on the type of whale. there are quite a few different types. The diet of a sperm whale is vastly different than the one that of a humpback whale. A humpback whale swims through the ocean straining out millions of tiny animals such as krill using its bubble net, while a sperm whale dives deep to hunt the giant squid, which it bites and tears apart with its huge teeth.
