Okhotsk Sea

About the Area

The Sea of Okhotsk is by far the richest of the Russian seas in terms of seabird numbers, with well over three million pairs.
The cool but fertile waters of the region support enormous fisheries that provide food for numerous birds. The sea varies greatly in depth and temperature. The northern section is relatively shallow, but other areas can be up to 5,000 feet (1,500 m) deep.

Currents make the water in the east much warmer than in the west, while areas close to Siberia are icy much of the year. These differences allow the sea to support a diverse array of fish and marine mammals.

Local Species
Selecetd species include the Golden king crab (Lithodes aequispina), Steller's sea lion (Eumetopias jubatus), Northern fur seal (Callorhinus ursinus), Dall's porpoise (Phocoenoides dalli), Ribbon seals (Phoca fasciata), Steller's sea eagle (Haliaeetus pelagicus), Common and thick-billed murre (Uria aalge and U. lomvia), and the Tufted and horned puffin (Fratercula cirrhata and F. corniculata).

Industrial and domestic pollution, oil exploration and over fishing are the most relevant threats.
