Yikes! Giant slugs!

Giant, hot-pink slugs found in Australia

Australia is home to some of the world’s most unique wildlife, from flightless birds capable of disemboweling a man to giant glow-in-dark earthworms. Now a new creature can be added to that list: large, bright pink slugs.

The existence of 8-inch fluorescent pink slugs on Mount Kaputar, a 5,000-foot peak in New South Wales, has only recently been confirmed.

Locals had long reported seeing the bizarre slugs after rainfall, but taxonomists just verified that Triboniophorus aff. graeffei is unique to the mountain’s alpine forest.

"As bright pink as you can imagine, that's how pink they are,” Michael Murphy, a ranger with the National Parks and Wildlife Service, told the Australian Broadcasting Corporation. "On a good morning, you can walk around and see hundreds of them, but only in that one area."

Scientists believe the slugs are survivors from an era when eastern Australia was home to rainforests. The creatures probably would have died out if a volcano hadn’t erupted in the area millions of years ago.
“The result of that eruption is a high-altitude haven for invertebrates and plant species that have been isolated for millions of years, after Australia dried out and the rainforests receded,” according to the Sydney Morning Herald.

At night, the slugs crawl up trees to feed on mold and moss, and while their bright pink coloration might seem detrimental to their survival, scientists say the fluorescent hue is actually beneficial. Fallen eucalyptus leaves are red and help hide the organism from predators.
