A mass dying of crabeater seals, Lobodon carcinophagus (Gray)
n 1955 some 3000 Crabeater Seals Lobodon carcinophagus wintered on the sea‐ice of the Crown Prince Gustav Channel. The seals, most of which were young, were ten times more numerous in 1955 than is normal in winter. Most of the animals died in the spring from a contagious disease whose effect was pro...
