It would seem to be something you'd see only in a cartoon or at a Phish concert, but according to park rangers in New South Wales, Australia, dozens of giant, fluorescent pink slugs have been popping up on a mountaintop there. The eight-inch creatures have been spotted only on Mount Kaputar, a 5,000-foot peak in the Nandewar Range in northern New South Wales. Scientists believe the eye-catching organisms are survivors from an era when Australia was home to rainforests. A series of volcanoes, millions of years of erosion and other geological changes “have carved a dramatic landscape at Mount Kaputar”, the park service wrote on its Facebook page, and unique arid conditions spared the slugs from extinction.
