Coat of an Antarctic Fur Seal (Arctocephalus gazelle). Fur seals rely heavily on their coats for insualtion against the near freezing waters that they hunt in. The pelts of this species were once used to make ladies' coats, almost leading to their exinction on South Georgia. A population survived on Bird Island and has since reestablished itself across large regions of South Georgia. Jason Harbour, South Georgia. November.
