Ankou, I wasn't going to bother replying as you'd only assume I'd been googling the answer, but with my old-school proper education head on, I remember - in the seas and on the very edge of the coastal regions of Antarctica live penguins (several sorts), seals (several sorts) and fish. On these, live some small parasites. Inland, there are no animals at all, unless you count microscopic lichens and algae and possibly the occasional tiny worm. Certainly no bears whatsoever. Wish I hadn't bothered responding to the original post.................
