The recently extinct Steller's sea cow was the largest known sirenian to have lived, reaching lengths of 10 metres (33 feet) and weights of 5 to 10 tonnes (5.5 to 11.0 short tons). [ 2 ] Sirenians have a large, fusiform body which reduces drag through the water and heavy bones that act as ballast to counteract the buoyancy of their blubber .

Steller's sea cow (Hydrodamalis gigas) is an extinct sirenian described by Georg Wilhelm Steller in 1741. At that time, it was found only around the Commander Islands in the Bering Sea between Alaska and Russia; its range extended across the North Pacific during the Pleistocene epoch, and likely contracted to such an extreme degree due to the glacial cycle.
Snakes will, however, be very welcome on “the world’s largest wildlife crossing,” under construction over the major 101 Freeway in Los Angeles. The Wallis Annenberg overpass will span 10 ...
Skull and limb-bone. The Cuesta sea cow, like the Steller's sea cow, or even modern manatees, was probably gregarious and lived in small family groups for relative safety. . Their bones were dense, and served as a sort of “ballast” to prevent their large bodies from floating, a likely adaptation due to their constant grazing of seagrasses on the shallow ocean fl
With 112 mammal species, Alaska ranks 12th of the 50 U.S. states in mammalian diversity. [1] Not included in this list is the Steller's sea cow, an extinct sirenian that was once native to Alaska's Aleutian Islands before being hunted to extinction in 1768. [2]
