Baikal seals hunt longfin Baikal sculpin, golomyanka (big Baikal oilfish), other fishes, and mollusks and other invertebrates. They can dive up to 400 meters (1,300 feet), and they can hold their breath for up to 40 minutes in search of food. During the winter months when the lake is covered with ice, they cut holes in the ice with their claws.
