The blue whale has one of the largest appetites of any animal, eating up to four tonnes of krill every day. Blue whales, which have baleen plates, feed by taking huge mouthfuls of water and food. They then push the water back out using their baleen plates as a strainer, keeping the food in their mouths.

How much krill does a gray whale eat?
of krill each day for about 120 days. It is estimated to take 1,000 kg (2,200 lbs.) of food to fill a blue whale’s stomach. Gray whales eat about 150,000 kg (340,000 lbs.)
How do whales feed on krill?
Skim feeders, like right whales, swim through krill- or plankton-rich areas of water with their mouths open. Food and water flow in but only water can flow back out through the baleen plates. The whale then uses its tongue to direct the krill and other food down its throat.
How many krill do whales eat?
When it comes to eating food, the blue whale can consume as many as 40 million krill per day, which ends up weighing close to 8,000 pounds of food daily!
What happens when whales eat krill?
Krill, small shrimp-like crustaceans* that blue whales eat almost exclusively, contain a significant amount of iron – a scarce nutrient in the open ocean. When whales eat krill they convert the protein into blubber and defecate* iron-rich waste.
What do blue whales eat other than krill?
What do blue whales eat besides krill? They consume fish, plankton, and other tiny crustaceans (like copepods and amphipods) floating in the water.
How do blue whales find krill?
Blue whales and their baleen whale cousins are known to use “bubble netting,” a technique in which the whales, sometimes swimming in teams, will dive below a krill swarm, sending up an enormous fountain of bubbles to alarm and displace the group. The disoriented krill are then much easier to catch.

Do blue whales eat humans?
Despite their large size, blue whales do not eat people. Actually, they couldn’t eat a person no matter how hard they tried to. Even though these marine mammals are the largest animals globally, several factors prevent them from eating a person.
Why do whales only eat krill?
For baleen, filtering whales, however, the story is different. There is plenty of krill in the ocean. One of the main constraints to eating, for baleen whales, is to open their mouths wide enough to swallow massive amounts of krill-containing water.
Do krill eat zooplankton?
Krill are considered an important trophic level connection – near the bottom of the food chain. They feed on phytoplankton and (to a lesser extent) zooplankton, yet also are the main source of food for many larger animals.

North Pacific Humpback whales can eat 9 tons of krill daily, while fin whales consume 8 tons. “It is an unimaginable amount of food.
Is blue whale vegetarian?
How do blue whales survive on krill?
This is how whales can easily eat a few tons of krill every day. In a nutshell, whales, some of the largest creatures on the planet, can survive by eating krill because they eat so many of them. To put this in perspective, consider a single grain of rice, which is positively puny in comparison to a human.
How many krill does a blue whale eat in one day?
Blue whales, the largest animal on Earth, can hold 90 metric tons of water and prey in a single lunge, allowing the whale to consume an estimated 3.6 metric tons of krill or 40 million individuals every day.
Do blue whales eat penguins?
Penguins are flightless birds that live in the southern regions of the Southern Hemisphere. These birds have multiple predators in the wild. Things that eat penguins include seals, sharks and other birds. Most species of whales are not known to prey on penguins.

Penguins eat krill (a shrimp-like crustacean in the family Euphausiidae), squids, and fishes. Various species of penguins have slightly different food preferences, which reduce competition among species. (See Appendix for information on diet for each species.)
Is whale vegetarian?
Whales are not herbivores but there are relatively few herbivorous animals in the sea. Their enormous weight is supported by the water, which explains how they can get so big.
Do leopard seals eat krill?
Penguins and humpbacks eat krill, but so do skuas, squid, fur seals, and crabeater seals. Leopard seals sometimes eat krill. A blue whale eats millions a day. Animals that don’t eat krill often feed on prey that does.
What animals eat zooplankton?
Small Predators
Mollusks, small crustaceans (such as shrimp and krill) and small fish like sardines and herring eat large amounts of the zooplankton.
What animal eats a whale?
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. However, there are very few reports of orcas actually killing blue whales.
Do killer whales eat zooplankton?
It also means killer whales must work hard to obtain the amount of food they need. Obviously, it is energetically advantageous to feed on organisms close to the base of the pyramid. Baleen whales (the whale at the third level of the pyramid) exemplify this strategy since they feed directly on zooplankton (krill).
Do killer whales eat sea otters?
Summary: With seals and sea lions in short supply in the North Pacific, killer whales are now feeding on sea otters, causing an abrupt decline in sea otter populations in western Alaska, according to researchers studying the area’s marine ecosystems.
Do killer whales eat elephant seals?
Types of prey
At Sea Lion Island, the main killer whale target are the elephant seals. Although killer whales are routinely observed chasing sea lions, penguins, and even steamer ducks, they concentrate on elephant seals, that is probably the species that guarantees the best return for the effort.

James Bartley (1870–1909) is the central figure in a late nineteenth-century story according to which he was swallowed whole by a sperm whale. He was found still living days later in the stomach of the whale, which was dead from harpooning.
Can a human survive being swallowed by a whale?
Despite occasional reports of whales scooping people into their mouths, it’s incredibly rare—and for all but one species, swallowing a human is physically impossible. On Friday, a lobster diver made headlines when he described miraculously surviving being “swallowed” by a humpback whale off Cape Cod, Massachusetts.
Why do whales not eat big fish?
The larger fish that feeds on this fish will produce only 1 unit of energy, which may not be enough to sustain the large whale. This is why Baleen whales have evolutionarily evolved into suspension feeders, using Baleen plates to take in large amounts of water and sift through to find small krill.
Is krill a zooplankton?
Krill are amongst the largest and most ecologically important zooplankton and they feed on phytoplankton.
What do krill eat zooplankton?
Krill eat green algae, phytoplankton, and larvaes. Krill eat a diet of algae, fish larvae, phytoplankton, and zooplankton. Krill are omnivores, though most krill species eat phytoplankt as their primary food source.
