The Caspian seal is a unique marine mammal found exclusively in the Caspian Sea, which is the largest enclosed inland body of water in the world. This species is characterized by its streamlined body, short limbs, and a spotted coat that varies in color from gray to brown. Adult Caspian seals typically weigh between 50 to 100 kilograms and can reach lengths of up to 1.5 meters. Caspian seals primarily feed on fish and invertebrates, playing a crucial role in the local ecosystem. They are known for their social behavior, often seen in groups on ice or rocky shores. Due to habitat loss and pollution, the Caspian seal population is currently considered vulnerable, prompting conservation efforts to protect this distinctive species.
