How many baby Subantarctic fur seals are in a litter?
A Subantarctic fur seal (Arctocephalus tropicalis) usually gives birth to around 1 babies.
Each of those little ones spend around 242 days as a fetus before they are released into the wild. Upon birth, they weight 4.35 kg (9.59 lbs) and measure 4.7 cm (0′ 2″). They are a member of the Otariidae family (genus: Arctocephalus). An adult Subantarctic fur seal grows up to a size of 1.63 meter (5′ 4″).
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 subantarctic fur seal (Arctocephalus tropicalis) is found in the southern parts of the Indian, Pacific, and Atlantic Oceans. It was first described by Gray in 1872 from a specimen recovered in northern Australia—hence the inappropriate specific name tropicalis.
