title: DIVING DEPTHS OF THE WEDDELL SEAL.
abstract: Dives as deep as 350 meters have been recorded for the Weddell seal in the waters of McMurdo Sound, Antarctica. It is suggested that Weddell seals possess a well-developed navigational system which enables them to swim long distances under thick ice shelves where light and breathing holes are limited.
