Stellers Sea Cow or Hydrodamalis gigas grew to be 26 to 30 ft. long as adults. This size made the sea cow one of the largest mammals of the Holocene epoch, along with whales, and was likely an adaptation to reduce its surface area-to-volume ratio and conserve heat.
Stellers Sea Cow or Hydrodamalis gigas was positively buoyant, meaning that it was unable to completely submerge. It had a very thick outer skin, 1 in., to prevent injury from sharp rocks. The sea cow’s blubber was 3 to 4 in. thick, another adaptation to the frigid climate of the Bering Sea. Stellers Sea Cow or Hydrodamalis gigas skin was brownish black, with white patches on some individuals.
It was smooth along its back and rough on its sides, with crater like depressions. This rough texture led to the animal being nicknamed the bark animal. Hair on its body was sparse, and the insides of the sea cow’s flippers were covered in bristles. The fore limbs were roughly 26 in. long, and the tail fluke was forked.
Stellers Sea Cow or Hydrodamalis gigas head was small and short in comparison to its huge body. The animal’s upper lip was large and broad, extending so far beyond the lower jaw that the mouth appeared to be located underneath the skull.
Stellers Sea Cow or Hydrodamalis gigas was toothless and instead had a dense array of interlacing white bristles on its upper lip. The bristles were about 1.5 in. in length and were used to tear seaweed stalks and hold food. The sea cow also had two keratinous plates located on its palate and mandible, used for chewing.
