The leopard seal at Marion Island, vagrant or seasonal transient?

Opportunistic sightings of some 19 different leopard seals Hydrurga leptonyxl/Ig at Marion Island (46°54'S, 37°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.
