How many baby Baikal seals are in a litter?
A Baikal seal (Phoca sibirica) usually gives birth to around 1 babies.
Each of those little ones spend around 277 days as a fetus before they are released into the wild. Upon birth, they weight 3.05 kg (6.72 lbs) and measure 6.9 cm (0′ 3″). They are a member of the Phocidae family (genus: Phoca). An adult Baikal seal grows up to a size of 1.28 meter (4′ 3″).
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 Baikal seal, Lake Baikal seal or nerpa (Pusa sibirica), is a species of earless seal endemic to Lake Baikal in Siberia, Russia. Like the Caspian seal, it is related to the Arctic ringed seal. The Baikal seal is one of the smallest true seals and the only exclusively freshwater pinniped species. A subpopulation of inland harbour seals living in the Hudson’s Bay region of Quebec, Canada (Lacs des Loups Marins harbour seals), the Saimaa ringed seal (a ringed seal subspecies) and the Ladoga seal (a ringed seal subspecies) are found in fresh water, but these are part of species that also have marine populations.The most recent population estimates are 80,000 to 100,000 animals, roughly equaling the expected carrying capacity of the lake. At present, the species is not considered threatened.
