It was the largest turnout the North East Skinny Dip has ever seen in its five-year history, and it was also the first time it has ever rained on the morning of the event. Revellers gathered from 5.30am on Sunday at Druridge Bay, in Northumberland, before baring all in the North Sea. (Photo by David Charlton Photography)

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.

These picture capture the hilarious moment a cheeky little bee decides to pick on a grumpy bear. A massive Kodiak bear is finding this pesky bee a pain in the bear-hind as it buzzes around his head just out of reach. This incredible comedic moment was captured in the bear den at Buffalo Zoo. Terry Cervi from Buffalo, New York, U.S.A. saw this incredible sight on one of her regular visits to her local zoo. (Photo by Terry Cervi/Caters News)
