Freshwater seal

Freshwater seals are pinnipeds which live in freshwater bodies. The group is paraphyletic in nature, the uniting factor being the environment in which these pinnipeds live. The vast majority of all modern seals live solely in saltwater habitats though this is likely due to the rarity of sufficiently large freshwater bodies rather than a limitation of seal biology. Many species of typically saltwater seals may occasionally frequent freshwater environments or include isolated populations in near coastal freshwater lakes. Additionally, a few species and subspecies are exclusively confined to freshwater bodies.
