No they eat krill small shrimp like creatures. Blue whales dont have any teeth......
A killer whale eats smaller fish, or smaller creatures in the ocean. They eat 2.5 - 5% of their body weight per day.
the blue wale originally eat up to 50 million krill each year so that weighing close to 1,000,000 pounds of food on a daily basis.
a average whale eat 4 tons of food a meal
200pd
Whale sharks are very large organisms. Though, they feed on one of the smallest organisms, krill. Krill eat plankton, which is what gives them energy.Then, Whale sharks eat the krill for their energy. They then use this energy by simply swimming.Though this seems easy to do, a Whale shark is much larger and uses a lot more energy to swim than we, humans, do.
Not usually but there may have been a few cases, they are known to feed on the whale if it has been killed. They probably would want to kill a Whale (but wouldn't take this risk they can weigh TONNES and tonnes) they probably wouldn't mess with one to be honest.
The only one that even dares to is the Killer Whale.
Toothed whales (Odontoceti) this group includes dolphins and orcas. These whales eat meat. Baleen whales (Mysticeti)This group includes the Blue whale, Grey whale and Minke. They pull in a mouthful of seawater and feed on plankton.
No
That would depend on the species of whale.
about 20 is optional but you can feed them how ever much u want
As for how often you feed them, depending on their size, about one or two worms a day should be enough for them.
No. It will eat one if its very hungry,other than that,no.
No but you can eat Cod
Probably 200. No one knows for sure but we DO know that many belugas and great white whales ate insects floating on top of the water, small fishes, crabs, crustaceans, and mollusks.
