Lost world of fanged frogs and giant rats discovered in Papua New Guinea

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.
