1. Baikal Seal
The Baikal Seal, also known as the nerpa, is a fascinating species endemic to Lake Baikal in Siberia. Unlike most seals that inhabit oceanic waters, this unique mammal has adapted to a freshwater environment, making it one of the few freshwater seals in the world. With a robust body and a thick layer of blubber, the Baikal seal is well-equipped to withstand the lake’s frigid temperatures. These seals primarily feed on the abundant fish found in Lake Baikal, showcasing remarkable diving skills. Their presence is essential for the ecological balance of this ancient and biodiverse lake.
