help Baikal Seal FAQ
How did seals get into landlocked Lake Baikal?
Scientists agree that the Baikal seal's ancestors came from marine seals, but the precise migration route remains debated. A commonly discussed scenario involves movement through ancient river systems connected to the Arctic Ocean.
Is the Baikal seal the only freshwater seal?
It is the only seal species whose entire population lives exclusively in freshwater. Other seals enter freshwater or include landlocked populations, but Pusa sibirica is endemic to Lake Baikal.
What do Baikal seals eat?
Their diet is dominated by small fish, particularly the endemic Baikal oilfish known as golomyanka. They also eat other local fishes and invertebrates while diving through the lake's deep, cold water.
Where do Baikal seals give birth?
Females give birth in snow-covered lairs on Lake Baikal's winter ice. The shelter protects the white-coated pups from severe weather during their earliest weeks.
