Krill are found in all oceans.

Krill swim in water off the coast, out in the open ocean, and around polar ice. Most krill feed and mate close to the surface, but a few species live at depths of up to 16,404 feet (5,000 meters).


Krill eat free-floating organisms known as plankton, which are microscopic plants and animals.


No species of krill are listed by the World Conservation Union (IUCN) as endangered or threatened. Still, over-fishing and climate change could threaten krill populations and the animals that depend on them.
