Weddell seal skull, Leptonychotes weddellii

Specimen collected by Robert Falcon Scotts British Antarctic Expedition 1910-1913, also known as the Terra Nova expedition. It had a broad scientific programme and collected thousands of geological and zoological specimens. The Weddell seal is found in coastal areas of the Antarctic mainland and some sub-Antarctic islands. It relies on holes in the ice for breathing and accessing water, and uses its teeth to create the holes and keep them open. Date: 1910
