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 the ...

When Caspian seals live in estuaries, they eat large amounts of the freshwater species, Sander lucioperca. Other prey include shrimp, crab, and silversides. [7] Being one of the top predators in the ecosystem, Caspian seals had hazardous chemicals found inside their bodies such as heavy metals, organochlorine compounds, and radionuclides. [8]
