California sea lions - has a thick layer of fat, short, thick fur that is dark brown to buff-colored, and a dog-like head. Males grow to 860 lb and 8 ft long, while females are significantly smaller, at 240 lb and 6.5 ft long. They have pointed muzzles, making them rather dog-like. Males are darker and bigger than females and grow a large crest of bone on the top of their heads as they reach sexual maturity. They also have thick furry manes, although they are not as well developed as the manes of adult male South American or Steller sea lions. Females are lighter in color than the males and pups are born dark, but lighten when they are several months old. When it is dry the skin is a chocolate brown color. The whiskers (called vibrissae) help the seal's sense of touch. The nostrils are closed in the resting state. The sea lion has small external ears and a good sense of hearing. It also has keen eyesight but no color vision.
The Steller sea lion are lighter in color than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Females tend to be slightly lighter than the males. Steller sea lion pups are born almost black, weighing around 50 lbs, and remain dark for several months. Females and males both grow rapidly until the fifth year, after which female growth slows down considerably, attaining on average 8 feet in length and 660 lbs. Males continue to grow until their secondary sexual traits appear in their fifth to eighth year. While only slightly longer than the females, males have much wider chests, necks and general forebody structure and weigh 1300-2500 lbs. Males are further distinguished by broader, higher foreheads, flatter snouts, and darker, slightly tuftier hair around their large necks, giving them a maned appearance. Indeed, their Latin name translates roughly as: "maned one with the broad forehead".

Sealions are sea mammals characterized by external ear flaps,long foreflippers the ability to walk on all fours and short, thick hair. The Paracus National Reserve in Peru covers some 800,000 acres of coastal areas and the Paracas Peninsula. The marine areas afford a home for sea lions, se otters, dolphins, over two hundred species of birds, and four kinds of sea tuttles.
