Description Ross seals are notably smaller than other Antarctic seals, reaching a length of about 2 m long and a weight of 200 kg. The coat is coloured dark-brown in the dorsal area and silvery-white beneath. At the onset of the Antarctic winter the coat fades gradually to become light brown. At close range, the Ross seal can be easily identified by its large eyes, which are 7 cm in diameter.
Habitat Although Weddell Seals, Crabeater Seals and Leopard Seals are ubiquitous in Antarctic waters, the Ross Seal is an uncommon and relatively unknown animal. It almost never leaves the Antarctic Ocean, with the very rare exception of stray animals found around sub-antarctic islands, and uniquely, off the south coast of Australia. Binomial name Leptonychotes weddellii (Lesson, 1826) The Weddell Seal (Leptonychotes weddellii), a true seal, is named after Sir James Weddell, commander of British sealing expeditions in the Weddell Sea. ...

Behaviour The Ross Seal hunts by diving for cephalopods and fish. It specialises more than other seals in hunting squid, which forms about two thirds of its diet. In common with other Antarctic seals, the Ross Seal is preyed upon by Killer Whales and Leopard Seals. Orders Sepiida Sepiolida Spirulida Teuthida Octopoda Vampyromorphida Nautilida The Cephalopods (head-foot) are the mollusk class Cephalopoda characterized by bilateral body symmetry, a prominent head, and a modification of the mollusk foot, a muscular hydrostat, into the form of arms or tentacles. ...

The Ross Seal is able to produce a variety of twittering sounds which carry a long distance underwater. The purpose of these sounds is unknown, though possibly they play a role in territoriality. It has been suggested that intruder be merged into this article or section. ...
In November the females give birth to their young on the ice. The pup is nursed for only four weeks and then left alone, shortly after which the female will mate underwater with a new partner. Within three years Ross Seals become sexually mature.
The life expectancy of a Ross Seal is thought to be around 20 years.
