What do blues whales eat?
Blue whales are the largest animals ever to live on our planet. They feed almost exclusively on krill, straining huge volumes of ocean water through their baleen plates (which hang from the roof of the mouth and work like a sieve). Some of the biggest individuals may eat up to 6 tons of krill a day.
What do the blue whale eat How much food do they eat at a time?
The blue whale, the largest animal in Earth’s history, eats about 16 tons of krill daily in the North Pacific, gobbling up these tiny shrimp-like crustaceans with a filter-feeding system in the mouth using baleen plates made of keratin, the substance found in people’s fingernails, scientists said on Wednesday..
What do whales eat eat?
They are carnivores that love to eat fish. Their teeth are not used for chewing, only for capturing and holding on to the food. Baleen whales feed by filtering or straining food from the water. They love to eat krill, fish, zooplankton, phytoplankton, and algae.
What do whales eat daily?
The huge whales can eat up to four tonnes of krill every day. Blue whales lunge through large swarms of krill with their mouths open, taking in more food in one mouthful than any other animal on Earth. Krill make up the vast majority of a blue whale’s diet.
Is blue whale vegetarian?

Do blue whales have predators?
Because of their size, power and speed, adult blue whales have virtually no natural ocean predators. The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”. However, there are very few reports of orcas actually killing blue whales.
Can blue whale eat human?
Despite their large size, blue whales do not eat people. Actually, they couldn’t eat a person no matter how hard they tried to. Without teeth, they lack the ability to tear apart their prey, so it would likely be impossible for these baleen whales to eat a human.
What are whales predators?
Because of their size, power and speed, adult blue whales have virtually no natural ocean predators. The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”. They have been known to work in groups to attack blue whales.
How much do blue whales eat?
A blue whale in the eastern North Pacific, for example, might eat between 10 and 20 tons of food a day. “That amount of food is somewhere in the range of 20 to 50 million calories,” says Matthew Savoca, a researcher at Stanford University and the lead author of the new study.
Do blue whales eat sharks?
That’s a great question! The only Cetacea known to hunt, attack successfully, and/or eat sharks is the killer whale (possibly the false killer whale as well, although not much is known or well researched about this species).
Can blue whale swallow a car?

What eats the blue whale?

Are blue whales carnivores?
Yes, blue whales are carnivores. They consume plankton and plankton consists of small shrimp-like animals, so they are not herbivores.
How do blue whales eat?
To eat, blue whales filter their food through stiff, bony, comb-like teeth called baleen plates. Their main diet is krill (euphausiids) and copepods. A blue whale can eat up to 8,000 lbs. of krill a day during its peak consumption period. It is estimated to take 2,200 lbs. of food to fill a blue whale’s stomach.
How do blue whales reproduce?
Blue whales reproduce via sexual meiosis. The male and female each produce haploid gametes. Male gametes are sperm, and the female gametes are eggs. A single sperm and egg fertilize to form a diploid zygote.
