How many baby South American fur seals are in a litter?
A South American fur seal (Arctocephalus australis) usually gives birth to around 1 babies.
Each of those little ones spend around 247 days as a fetus before they are released into the wild. Upon birth, they weight 4.45 kg (9.81 lbs) and measure 21.5 cm (0′ 9″). They are a member of the Otariidae family (genus: Arctocephalus). An adult South American fur seal grows up to a size of 1.65 meter (5′ 6″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
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 However, population counts are sparse and outdated.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.
