This seal is much smaller than the rest of the Antarctic seals. The body length is about 2 meters, and weigh up to 200 kg. The subcutaneous fat layer is very developed. A very thick neck with folds is characteristic, into which the beast almost completely draws its head in. In this case, it becomes like a barrel. The general color of the fur is dark brown, almost black, with a lead shade, lighter on the sides and belly. Life expectancy is approximately 20 years.
The Ross seal is a rather rare species, and relatively little studied. Distributed in remote areas of Antarctica .
