krill

Tiny ocean crustaceans

Krill are small shrimp-like crustaceans that swarm in vast numbers in cold ocean waters, particularly around Antarctica.

They form the foundation of marine food chains, serving as the primary food source for whales, seals, penguins, and fish.

Despite their tiny size—typically one to two centimeters—their collective biomass is among the largest of any animal species on Earth.
