What is the maximal age a South American fur seal reaches?
An adult South American fur seal (Arctocephalus australis) usually gets as old as 21 years.
South American fur seals are around 247 days in the womb of their mother. When born, they weight 4.45 kg (9.81 lbs) and measure 21.5 cm (0′ 9″). As a member of the Otariidae family (genus: Arctocephalus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 1.65 meter (5′ 6″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The South American fur seal (Arctocephalus australis) breeds on the coasts of Peru, Chile, the Falkland Islands, Argentina, Uruguay and Brazil. The total population is around 250,000. However, population counts are sparse and outdated. Although Uruguay has long been considered to be the largest population of South American fur seals, recent census data indicates that the largest breeding population of A. a. australis (that breeds in Chile, Falklands, Argentina, Uruguay) are at the Falkland Islands (estimated pup abundance ~36,000) followed by Uruguay (pup abundance ~31,000) . The population of South American fur seals in 1999 was estimated at 390,000, a drop from a 1987 estimate of 500,000 – however a paucity of population data, combined with inconsistent census methods, makes it difficult to interpret global population trends.
