It was first discovered by Europeans in 1741 and rendered extinct by 1768. It was a 30-foot long, plant-eating aquatic mammal, weighing up to 12 tons, that lived in large herds on the coasts of Alaska and Kamchatka.Steller made his observations as part of Vitus Berings second voyage, during which the crew was shipwrecked for 9 months on Bering Island, from November 1741 to August 1742. This voyage was undertaken as part of the Great Northern Expedition, commissioned by the Imperial Academy of Sciences in St. Petersburg, to prosecute the exploration of the North Pacific and western North America.This English translation originally appeared in 1899, in an appendix to The Fur Seals and Fur-Seal Islands of the North Pacific Ocean, edited by David Starr Jordan, Part 3 (Washington, 1899), pp. 179218.A brief bibliography, links to online works and sites, and illustrations have been added by the present editor.The original Latin work was published in St. Petersburg in 1751.
