The crabeater seal, Lobodon carcinophaga, is found in the pack ice zones surrounding Antarctica. It primarily feeds on krill, despite its name, using its uniquely lobed teeth to filter these small crustaceans from the water. Crabeater seals are known for their streamlined bodies and excellent swimming abilities, aiding their survival in harsh polar environments.

Lobodon carcinophaga, commonly known as the crabeater seal, is native to the Antarctic region. Its geographical distribution extends along the circumpolar Antarctic pack ice zone, primarily on the coasts of Antarctica and adjacent islands.

The crabeater seal inhabits the cold, icy waters surrounding Antarctica. It is typically found on the pack ice, which provides a platform for resting, breeding, and molting. This region is characterized by extreme cold temperatures, with sea ice present year-round, though it experiences seasonal fluctuations.

Crabeater seals are adapted to a life predominantly spent on the ice and in the water. They feed primarily on Antarctic krill, making them a crucial part of the Antarctic marine food web. Their ecological niche is highly specialized to the ice-covered regions, where they are well-camouflaged and protected from predators like orcas and leopard seals.
