摘要：

Opportunistic sightings of some 19 different leopard seals Hydrurga leptonyx at Marion Island (46 degrees 54'S, 37 degrees 45'E) in the South Indian Ocean were recorded mostly in September to October between 1980 and 2005. Largely immature and both in poor and good condition, they might benefit from a locally abundant food resource. The species appear to be a regular member of the marine fauna of the region, occasionally hauling out on the island coastline as seasonal transients of the archipelago's marine environment.
