The South American Sea Lion (Otaria flavescens, formerly Otaria byronia), also called the Southern Sea Lion and the Patagonian Sea Lion, is a sea lion found on the Chilean, Peruvian, Uruguayan and Argentine coasts. Its scientific name was subject to controversy, with some taxonomists referring to it as Otaria flavescens and other referring to it as Otaria byronia. The former eventually won out. Locally, it is known by several names though the most common ones are "lobo marino" (sea wolf) and "león marino" (sea lion).
Physical description
The South American sea lion is perhaps the archetypal sea lion in appearance. Males have a very large head with a well developed mane making them the most lionesque of the eared seals. They are twice the weight of females. Both males and females are orange-coloured with upturned snouts. The manes on males are lighter than females, and female fur on the head and neck is lighter than that of males. Pups are born black or dark brown and molt into a more chocolate colour. The South American Sea Lion's size and weight can vary quite a lot. Adult males can grow over 2.73 m (9 ft) and weigh up to 350 kg (770 lb). Adult females grow up to 1.8–2 m (6–7 ft) and weigh about half the weight of the males, around 150 kg (330 lb). These sea lions are the most sexually dimorphic of the five sea lion species.
