The scientific name of the Caspian seal is Phoca caspica, an animal belonging to the genus Phoca of the family Phocidae.
Caspian seals live in small groups in the middle or southern coast of the Caspian Sea in summer, migrate north in autumn, and form breeding groups on the ice. They give birth on fixed ice from mid-January to late February without building a nest. Newborns weigh 1.2 to 2.8 kg and the lactation period is 4 to 5 weeks. Mating occurs from late February to early March. Females reach sexual maturity at 4 to 6 years old and males at 6 years old.
Caspian seals mainly eat carp, gobies and crustaceans. They go to the estuary to eat carp, cyprinids and zander. Sea eagles prey on Caspian seals, causing the death of a large number of young seals. In 1978, 17 to 40% of Caspian seals in Astrakhan were killed by wolves. They are also hunted by humans. Due to industrial development, pollutants and pesticides have caused them to become sick. Since the late 1990s, they have suffered from canine distemper.
In the 1980s, there were about 400,000 Caspian seals, a significant drop from 1.5 million a century ago. It is estimated that there are currently 470,000 to 650,000.
In 2008, the Caspian seal was listed as an endangered species by the World Conservation Union.
