Best answer:

Steller's sea cow (Hydrodamalis gigas) is an extinct species of Syrian mammal of the Dugongidae3 family that measured about 8 meters in length (up to 10 in some cases) and weighed from 4 to 10 tons, which featured the bracketed tail and a rough black skin. In comparison with its manatee and dugong relatives, it shows the teeth reduced to its minimum numerical expression, being the form best adapted to marine life. The greatest sirenium ever, was discovered and described for the first time by the doctor Georg Wilhelm Steller, a member of the Russian expedition of Vitus Bering in 1741, lost on the island of Arachka (then Bering Island), opposite Kamchatka. His report not only excited zoologists, but also seal and whaling hunters who saw a lucrative business, and from that moment it became a prey coveted by sailors, who hunted it in large numbers until its extinction in 1768. The ships followed one after another in front of Kamchatka, and just 27 years after its discovery Steller's last sea cow was shot down. From the year 1854 there was no trace left.
