Presence of the leopard seal, hydrurga leptonyx (de blainville, 1820), on the coast of Chile: an example of the Antarctica - south America connection in the marine environment
Sightings of 115 leopard seals, Hydrurga leptonyx, have been recorded along the Chilean coasts from 1927 to 2010. Mostly immature seals occurred in northern and central Chile (18°20´S-39°59´S), especially in winter, while immature and adult individuals of both sexes and in good condition were common...
