It depends on the whale. I mean they are big so they do eat very much!
it is their main food source
Bryde's Whales are Baleen Whales so that means it will eat Krill and some Phytoplankton.
it varies
Whales are carnivores, so they cannot eat plants. Humpback whales are baleen whales, which means that they don't even eat large fishes or seals; they eat plankton.
humpback whales are sopose to eat so they eat almost every day
Whales don't eat coral. Coral is very hard, and most whales don't have teeth. They *do* eat *krill* in massive quantities.
Belugas are toothed whales, they don't deliberately eat things as small as krill.
They eat small fish in schools and zooplankton so they do depending on the species. Fin whales, humpback whales, Bryde's whales and sei whales all eat small fish.
No. Humpback whales only eat krill, small fish, etc. Basically, they only eat animals that are much smaller than they are.Humpbacks are baleen whales, filter feeders. They don't have the teeth to eat anything that big.
blue whales can't swallow things larger than a grapefruit so no whales i think they eat krill mainly
No. Killer whales eat gray whales.
