While the Baikal Seal is the only unique species of pinniped to live in a purely freshwater environment for the duration of their lives, various species of typically saltwater seals may occasionally frequent freshwater environments or include isolated populations in near coastal freshwater lakes.
Jun 18, 2019 · Iliamna Lake is the largest body of freshwater in Alaska and the home to a unique population of seal that spends its entire life in freshwater. Since most seal populations live in saltwater or travel between salt and freshwater, this population of Iliamna Lake seals is globally rare.
- Baikal seal (Pusa sibirica) Endemic to Lake Baikal. Of course, if just one of the world’s freshwater systems could have an isolated population of obligate freshwater seals, it would be Lake Baikal.
- Caspian seal (Pusa caspica) Native to the Caspian Sea. The Caspian seal favors the brackish waters of the Caspian Sea, but its subpopulations may routinely enter purely freshwater tributaries like the Volga River and Ural River.
- Iliamna Lake seal (Phoca vitulina richardsi) Endemic to Iliamna Lake. A subspecies of the harbor seal, the Iliamna Lake seal has a landlocked population in Alaska’s largest body of freshwater.
- Ladoga ringed seal (Pusa hispida ladogensis) Endemic to Lake Ladoga. Lake Ladoga is a large freshwater system in northwestern Russia, where it is connected to thousands of rivers.
May 20, 2019 · Researchers made the findings after drilling into the canines of harvested Iliamna Lake seals. These teeth grow throughout a seal's life, Brennan explained, and contain "lifelong chemical...
Feb 14, 2024 · Seals don't necessarily need to be in salt water to survive. Unlike other marine animals, they are not very sensitive to the salinity of water. It is true that after a while their eyes can get irritated.
Salt Water. Pinnipeds that live in the sea must rely on freshwater to survive. Special adaptations help them retain as much freshwater as possible. Most freshwater comes from a pinniped’s meal—Harbor seals obtain about 90 percent of their freshwater from the fish they eat.

New research by Sean Brennan, a postdoctoral research associate at the University of Washington and colleagues suggests that the roughly 400 harbor seals live permanently in Iliamna Lake, chasing freshwater fish in the lake year-round, supplemented by salmon in the summer.
