Marine Otter (Lontra felina)
…a rare species of otter that occurs along the coast of western South America, from northern Peru to Cape Horn and Isla de Los Estados. Like its common name suggests L.felina spends most of its life out in the ocean, however it also inhabits freshwater and esturarine habitats as well unlike the Sea Otter (E.lutris). Like sea otters marine otters are nimble in the water and will dive for fish, cephalopods, crustaceans and molluscs. It will emerge from the sea to rocky islets to rest and eat, individuals will claim rocks and will defend them from other otters. Despite this, they are not territorial and they have even been seen fishing cooperatively.
Lontra felina is currently listed as endangered by the IUCN, and faces threats from hunting for its pelts and habitat loss. Its also threatened by water pollution and over-fishing of its prey species.
