Pusa 1718
''Pusa'' is a genus of the earless seals, within the family Phocidae. The three species of this genus were split from the genus ''Phoca'', and some sources still give ''Phoca'' as an acceptable synonym for ''Pusa''. The three species in this genus are found in Arctic and subarctic regions, as well as around the Caspian Sea. This includes these countries and regions: Russia, Finland, Scandinavia, Great Britain, Britain, Greenland, Canada, the United States, Iran, Azerbaijan, Kazakhstan, and Japan. Due to changing local environmental conditions, the ringed seals found in the Canadian region has varied patterns of growth. The northern Canadian ringed seals grow slowly to a larger size, while the southern seals grow quickly to a smaller size. Only the Caspian seal species of ''Pusa'' is endangered, while two subspecies of the ringed seal are Vulnerable species, vulnerable and endangered, Ladoga seal and Saimaa ringed seal respectively.

Baikal Seal
The Baikal seal, Lake Baikal seal or (''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.Randall R. Reeves, Brent S. Stewart, Phillip J. clapham, James A. Powell, ''"National Audubon Society Guide to the Marine Mammals of the World"'', Alfred A. Knopf publishing, New York, 2002 A subpopulation of inland harbour seals living in the Hudson Bay region of Quebec, Canada (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. 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. Descrip ...
