One year ago, in September 2009, 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. 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 team are believed to be the first scientists to enter the mountainous Bosavi crater.
They found the three-kilometre wide crater populated by spectacular birds of paradise and in the absence of big cats and monkeys, which are found in the remote jungles of the Amazon and Sumatra, the main predators are giant monitor lizards while kangaroos have evolved to live in trees. New species include a camouflaged gecko, a fanged frog and a fish called the Henamo grunter, named because it makes grunting noises from its swim bladder.
