01Species profile

The resident seal of Baengnyeongdo in the West Sea

A small true seal of the genus Phoca (family Phocidae, order Carnivora) and Korea's only resident pinniped. Rather than a species observed directly while diving, it is treated as a conservation and ecological flagship species.

02Habitat & season

Colony at Mulbeom Rock, Baengnyeongdo

A migratory species that moves between Baengnyeongdo, the North Korean West Sea coast (Jangsangot), and the icy waters of China's Liaodong Bay to breed and grow. Once recorded across the East, West, and South Seas, its domestic colony is now concentrated at Baengnyeongdo in the West Sea (Mulbeom Rock, Yeonbong Rock, Dumujin).
