Habitat
Baikal seals are endemic to Lake Baikal in Siberia, Russia, inhabiting both shallow coastal waters and deep pelagic zones up to 1,000 meters. They prefer icy environments, often hauling out on ice floes or rocky shores, and are adapted to freshwater conditions in this isolated lake.
Diet
Baikal seals primarily eat fish such as the Baikal oilfish (golomyanka) and sculpins, which they hunt in deep waters. They also consume amphipods and other invertebrates. Feeding typically occurs at night or during dives to depths of 50-200 meters.
Behavior
Baikal seals are mostly solitary but may form small groups on ice floes for resting or molting. They are agile swimmers, capable of diving for up to 20 minutes, and are active year-round with peaks in activity during the ice-free summer. They exhibit minimal territorial behavior, though males may compete for mates during breeding season.
Conservation Status
The Baikal seal is listed as Vulnerable on the IUCN Red List due to threats from pollution, overfishing of prey, and climate change impacting ice cover. Population trends indicate a decline over the past few decades.
