Ross Seal

From an old slide. Ross Seals are the rarest of the Antarctic seals. This was only the second seen by ANARE expeditions, though the base at Mawson had been operating for 13 years at this time, so we were fortunate to encounter it. Wikipedia gives an estimated total population of about 130,000 (give or take 100,000 !). They have the strange habit of inflating their throat like a bullfrog when disturbed.
