| Topics: |  Marine Ecology Biodiversity |
Eumetopias is a genus of just one species (a “monotypic” genus) within the eared seal family of sixteen species - the Steller Sea Lion.
Eared seals include sea lions and fur seals. Together with the families of true seals and Walruses, Eared seals form the group of marine mammals known as Pinnipeds.
Eared seals differ from the true seals in having small external earflaps and hind flippers that can be turned to face forwards. Together with strong front flippers, this gives them extra mobility on land and an adult fur seal can move extremely fast across the beach if it has to. They also use their front flippers for swimming, whereas true seals use their hind flippers.

Conservation Status  |
Scientific Classification Kingdom: Anamalia (Animals) |
Steller's Sea Lion is found on the North Pacific coasts.
The world population of Steller's sea lions has been undergoing a mysterious decline; since 1980, numbers have dropped from over 300,000 individuals to fewer than 100,000. Despite this well-documented and worrying decline, the causes are still being debated. The species is listed as "Endangered."
Like other Eared seals, the male Stellar Sea Lion is considerably larger than the female.

The Author
The Encyclopedia of Life (EOL) is an ambitious, even audacious project to organize and make available via the Internet virtually all information about life present on Earth. At its heart lies a series of Web sites—one for each of the approximately 1.8 million known species—that provide the entry points to this vast array of knowledge. The entry-point for each site is a species page suitable for the general public, but with several linked pages aimed at more specialized users. The sites spark ... (Full Bio)
