Team of scientists find more than 40 previously unidentified species in remote volcanic crater

Wow, I'm even more jealous of my boy, who's off hiking in PNG with his family.

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.
