This huge walrus is all brawn - and looks just like a brain. The male looks very similar to a human brain thanks to the pink lumps - known as nodules - all over his shoulders and back. Sharp white tusks, pink nodules and a whiskered moustache make for a very odd looking marine mammal.
The fully-grown adult is almost 10ft tall and weighs around a ton. Photographer Franco Banfi, of Cadro, Switzerland, was in Svalbard, in the Arctic Ocean, when he spotted the herd of walruses. SEE OUR COPY FOR DETAILS.
