For other uses of the term "sea lion", see Sea lion (disambiguation).

Sea lions are any of seven species in six genera of modern pinnipeds including one extinct one (the Japanese sea lion). Sea lions are characterized by the presence of external ear pinnae or flaps, long front flippers, and the ability to walk on four flippers on land. Their range extends from the subarctic to tropical waters of the global ocean in both the northern and southern hemispheres with the notable exception of the Atlantic Ocean. They are generally found in shallow waters of coastal areas of both with abundant food resources.
