Steller sea lion(Eumetopias jubatus)

The steller sea lion is an endangered species as listed in the Red Data Book of Russia. The largest populations of steller sea lions can be found in the offshore areas of both the Bering Sea and the Okhotsk Sea; smaller numbers of these lions live off the Alaskan coasts and in the Sea of Japan. Males can attain a length of up to 3.4 meters and a weight of up to 1 ton. Females are slightly smaller at up to 2.1 m (seldom up to 2.6 m) in length and up to 350 kg in weight. Steller sea lions feed on fish and cephalopod molluscs. Their enemies are orcas, polar bears and sharks. Steller sea lions have been living in the Lithuanian Sea Museum since 1982. Their diet is rather rich: it includes horse mackerel, mackerel, Baltic herring, herring and Baltic sprat. Each of the sea lions consumes approximately 40 kg of fish every day.
