A Baikal seal reacts to a breeder at the aquarium in All-Russian Exhibition Center in Moscow, capital of Russia, in this photo released Saturday. The Baikal seal, also known as Phoca sibirica, is the only species of phocids (true seals) distributed in a freshwater region. This species is endemic to Lake Baikal, located in the midst of Siberia far from the habitat of their marine relatives. The origin of this species has therefore received substantial attention.SD-Agencies
