Baikal Seal

The Baikal seal (Pusa sibirica), also known as Lake Baikal seal or nerpa (нерпа), is a species of earless seal endemic to Lake Baikal in Siberia, Russia. The Baikal seal is one of the smallest earless/true seals, and one of the few exclusively freshwater pinniped species. The related Caspian seal inhabits another lake, albeit being saltwater, the Caspian Sea. Both species are closely related to the ringed seal, which inhabits the Arctic Ocean. A subpopulation of inland harbour seals living in the Hudson Bay region of Quebec, Canada (the Lacs des Loups Marins harbour seals), as well as the Saimaa ringed seal and the Ladoga seal (both ringed seal subspecies), are also found in fresh water, but these seals are part of species that also have marine populations, instead of being distinct species. 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. == Description == The Baikal seal is one of the smallest true seals. Adults typically grow to 1.1–1.4 m (3 ft 7 in – 4 ft 7 in) in length with a body mass from 63 to 70 kg (139…
