This fantastically pink slug, Triboniophorus aff. graeffei, is only found on Mount Kaputar, a mountaintop in New South Wales, Australia. According to scientists, the slugs and several other strange species are from the days when this region was a damp rainforest. When Mount Kaputar erupted 17 million years ago, it preserved a very unusual ecosystem. "A series of volcanos and millions of years of erosion have carved a dramatic landscape at Mount Kaputar National Park, creating a fascinating world with some very colourful locals," writes the NSW National Parks and Wildlife Service on its Facebook page.
