The Baikal seal is a unique species of freshwater seal found only in Lake Baikal, the deepest and oldest lake in the world, located in Siberia, Russia. These seals are well-adapted to their cold environment, with a thick layer of blubber that keeps them warm. They have a distinctive spotted coat and can grow up to 1.5 meters long. Baikal seals are known for their playful nature and spend much of their time swimming and diving in the lake. They primarily feed on fish and invertebrates, making them an important part of the Lake Baikal ecosystem. Their population is currently stable, but they face threats from pollution and climate change.
