Role in the Food Chain Krill feed on phytoplankton, microscopic, single-celled plants that drift near the ocean's surface and live off carbon dioxide and the sun's rays. They in turn are the main staple in the diets of literally hundreds of different animals, from fish, to birds, to baleen whales.

What is a Krills diet?
Antarctic krill are filter feeders that eat tiny phytoplankton (pelagic algae). They use their small, hair-like legs to filter out these microscopic algae that bloom in the nutrient-rich waters around Antarctica. These blooms are densest at the ice edge, so Antarctic krill are often also densest near that system.
What do Antarctic Krills eat?
For their own meals, Antarctic krill eat small plants like phytoplankton, as well as algae under the surface of sea ice. Krill have the ability to shrink their bodies and undergo long periods of starvation.
What do krill and shrimp eat?
Krill are small crustaceans resembling shrimp that are found primarily in the Arctic and Antarctic oceans. Vital to the planet's marine ecosystem, their diet consists of phytoplankton, copepods, zooplankton and algae.
What do Antarctic animals eat?
All animals depend on krill for their survival. Krill eat phytoplankton (tiny ocean plants) and zooplankton (tiny ocean creatures), squid eat krill, penguins eat krill and squid, fish eat krill and other fish, seals eat krill, fish and squid, Leopard seals eat krill, squid, fish and penguins.
Do krill eat Pteropods?
Pteropods are eaten by marine species ranging in size from tiny krill to whales and are an important source of food for North Pacific juvenile salmon. The photos above show what happens to a pteropod's shell in seawater that is too acidic.
What do pelagic algae eat?
Antarctic krill are filter feeders that eat tiny phytoplankton (pelagic algae). They use their small, hair-like legs to filter out these microscopic algae that bloom in the nutrient-rich waters around Antarctica. These blooms are densest at the ice edge, so Antarctic krill are often also densest near that system.
What do copepods feed on?
Tiny crustacean zooplankton called “copepods” are like cows of the sea, eating the phytoplankton and converting the sun's energy into food for higher trophic levels in the food web. Copepods are some of the most abundant animals on the planet.
What is Antarctica's top predator?
One of the top predators in the Antarctic is the leopard seal. Its scientific name is Hydrurga leptonix. They get their common name (leopard) from the spots on their fur that resemble a leopard. They feed only in the water although they have been known to rock an iceberg to tip off a young seal or a penguin.
What do Antarctic herbivores eat?
The major proportion passes through the food web at the hub of which is the Antarctic krill (a key herbivore) and a variety of zooplankton. Predators of krill such as the baleen whales, crab eater seals, penguins, fish and squid are the primary predators of the food web.
What do Antarctic birds eat?
Diet: Like most animals that call the White Continent their home, the birds' diet is based in the ocean itself. Krill and other invertebrates are the cornerstone of their diet, which also typically includes fish and squid. Some of the larger birds even eat carrion, eggs, and chicks.
Can you eat fish from Antarctica?
“You can fish, but only with a scientific collection permit. All of the animals of the Southern Ocean are protected under the international Antarctic Treaty. So, even though there are species of cod that are edible, they are protected and can't be caught, unless for scientific study.”
Who eats krill?
Krill is the near-exclusive food for giant blue whales, and seabirds like auklets and shearwaters. Commercially valuable salmon, rockfish, flatfish, sardines and squid thrive on krill. When abundant, animals migrate thousands of miles to feed on krill.
What do most zooplankton eat?
Most zooplankton eat phytoplankton, and most are, in turn, eaten by larger animals (or by each other). Krill may be the most well-known type of zooplankton; they are a major component of the diet of humpback, right, and blue whales.
What is the difference between shrimp and krill?
Main Differences Between Krill and Shrimp
Krill has only a pair of antennae, while shrimp has two pairs of antennae. Krill are herbivores. On the other hand, shrimp are omnivores. Krill are generally smaller in size, whereas shrimp are comparatively larger.
