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 .

Texas avian flu outbreak spreads from cows to humans and chickens, but is ‘a very, very small part of the overall picture,’ state agriculture boss says Dylan Sloan April 3, 2024 at 11:08 AM
The earliest known sea cows, of the families †Prorastomidae and †Protosirenidae, were both confined to the Eocene, and were pig-sized, four-legged, amphibious creatures. [19] The first members of Dugongidae appeared by the middle Eocene. [20] At this point, sea cows were fully aquatic. [19] Pinnipeds split from other caniforms 50 mya during ...
The West Indian manatee is the largest living member of the sirenians (order Sirenia), a group of large aquatic mammals that includes the dugong, other manatees, and the extinct Steller's sea cow. Manatees are herbivores , have developed vocal communication abilities, and are covered in highly sensitive whiskers (called vibrissae ) that are ...
Sea cows at that point in time could be as large as 5 meters (about 16 feet) long, Benites-Palomino said, and their fatty tissue would have been a good food source. Today, crocodiles, orcas and ...
