Meet Lake Baikal's unique freshwater Nerpa seal

Lake Baikal is the largest and most deep freshwater lake in the world and contains more water than all the great lakes of North America together. Originally from the lake whose name carries, the Baikal seal is the only seal exclusively of fresh water in the world.

World's only freshwater seal

The world's only freshwater seal is known as the Baikal seal, also called the Nerpa. It is found exclusively in Lake Baikal, which is located in Russia and is the largest freshwater lake in the world by volume.

Baikal seals are relatively small, with males growing up to 1.5 meters (5 feet) in length and females growing up to 1.3 meters (4.3 feet) in length. They have dark gray or brown fur, with a lighter gray underbelly. Baikal seals have webbed feet, which they use for swimming and diving.

Baikal seals feed mainly on fish, but also consume crustaceans and other small aquatic animals. They can dive to depths of up to 300 meters (1,000 feet) and can stay underwater for up to 70 minutes.

Baikal seals are an important part of the ecosystem of Lake Baikal, and are considered a keystone species. They help to regulate the population of fish in the lake, and are preyed upon by other animals, such as the Siberian tiger.

They help to regulate the population of fish and other aquatic animals. As predators, freshwater seals play an important role in maintaining the balance of the food web in freshwater ecosystems.

Threats due to human activity

However, Baikal seals are currently facing threats due to human activity. Pollution, overfishing, and habitat destruction are all putting pressure on the population of Baikal seals.

In addition, the construction of dams and other hydroelectric projects on the rivers that flow into Lake Baikal could also have a negative impact on the seal population.

Efforts are underway to protect the Baikal seals and their habitat. The Russian government has designated the lake and its surrounding area as a protected natural area, and several conservation organizations are working to promote sustainable fishing practices and reduce pollution in the lake.

Freshwater seal population

The population of Baikal seals, also known as nerpa, in Lake Baikal is estimated to be between 60,000 and 100,000 individuals.

The population has been relatively stable over the past few decades, with some fluctuations due to natural factors such as changes in prey availability and breeding success.
