Abstract
Seeotter. Ein auf dem Rücken schwimmendes Weibchen säugt sein Junges. Einige Seeottern fressen, auf dem Rücken schwimmend, große Krabben. Muscheln werden geöffnet, indem die Schalen mit Hilfe der Vorderpfoten gegen große, auf dem Bauch liegende Steine geschlagen werden. Häufiges Drehen um die Längsachse dient der Sicherung.
The film shows different manners of behaviour of the sea otter (Enhydra lutris). A female swimming on its back nurses a young one; it turns round its longer axis while the young one follows the tit. Several Sea Otters swimming on their backs are eating big crabs. With their teeth they tear off legs and eat them, finally the carapace is licked clean. Sea Otters use clain stones thick as a fist in order to crush mussels. They lay the stones upon their bellies and beat the mussels with their forepaws many times against the stone until it breaks into pieces and the soft interior (mollusc) is eaten. Also while opening and eating mussels Sea Otters turn often round their longer axis holding stone and mussel fast.
