During December 1966, observations were made on the hunting and feeding habits of an individual Weddell seal(Leptonychotes weddelliLesson) at a fishing hole in the ice above a depth of 300 m of water, near McMurdo Station. The seal appeared regularly every day, usually within 10 minutes of 1800 hours, and started feeding, sometimes for as long as 8 hours. The prey fish, once caught, was killed and eaten underwater, with the seal frequently surfacing to breathe. The fish caught varied in weight between 15 and 65 1b, and were all the same species, identified asDissostichus mawsoniNorman.
