Antarctic Krill
Euphausia superbaRed
The Antarctic Krill forms immense swarms in polar waters, converting microscopic plankton into energy that can feed fish, penguins, seals, and whales. Though each individual is small, together they underpin one of the largest marine food systems on Earth.

The animal behind the card
At night many swarms rise toward the surface to feed, then sink again by day, a daily vertical migration that redistributes carbon and nutrients through the water column. Their bodies can glow faintly through bioluminescent organs, adding brief flashes to the blue darkness.
Because warming seas and changing ice cycles affect plankton and spawning conditions, krill are tightly linked to climate shifts. Protecting Southern Ocean ecosystems depends in part on understanding this tiny crustacean's outsized role.
Bestiary facts
Antarctic krill are tiny animals with planetary importance, feeding giants by the swarm.
