A lost world populated by fanged frogs, grunting fish and tiny bear-like creatures has been discovered in a remote volcanic crater on the Pacific island of Papua New Guinea.
A team of scientists from Britain, the United States and Papua New Guinea found more than 40 previously unidentified species when they climbed into the kilometre-deep crater of Mount Bosavi and explored a pristine jungle habitat teeming with life that has evolved in isolation since the volcano last erupted 200,000 years ago. In a remarkably rich haul from just five weeks of exploration, the biologists discovered 16 frogs which have never before been recorded by science, at least three new fish, a new bat and a giant rat, which may turn out to be the biggest in the world.
The discoveries are being seen as fresh evidence of the richness of the world's rainforests and the explorers hope their finds will add weight to calls for international action to prevent the demise of similar ecosystems. They said Papua New Guinea's rainforest is currently being destroyed at the rate of 3.5% a year.
"It was mind-blowing to be there and it is clearly time we pulled our finger out and decided these habitats are worth us saving," said Dr George McGavin who headed the expedition.
