摘要

Leopard seals inhabit the pack-ice rim of Antarctica, and they regularly haul out on Antarctic and Subantarctic islands. Occasionally, vagrants are sighted further north in South America, Australia, New Zealand, and very rarely in southern Africa and Oceania. Here we report on an observation made on the 15th of July 2010 of a single 3-m-long juvenile leopard seal at 'Die Dam' in the Western Cape, South Africa (34 degrees 45.772'S, 19 degrees 42.582'E). We searched historical records and found details of four observations of leopard seals along the coast of South Africa since 1946. All of these sightings were of juvenile animals. The relative scarcity of observations is a likely reflection of the great distance from Antarctica and the Subantarctic to South Africa.
