A new species of giant rat has been discovered deep in the jungle of Papua New Guinea.
The rat, which has no fear of humans, measures 82cm long, placing it among the largest species of rat known anywhere in the world.
The creature, which has not yet been formally described, was discovered by an expedition team filming the BBC programme Lost Land of the Volcano.
It is one of a number of exotic animals found by the expedition team.
Like the other exotic species, the rat is believed to live within the Mount Bosavi crater, and nowhere else.
"This is one of the world's largest rats. It is a true rat, the same kind you find in the city sewers," says Dr Kristofer Helgen, a mammalogist based at the Smithsonian National Museum of Natural History who accompanied the BBC expedition team.
Initially, the giant rat was first captured on film by an infrared camera trap, which BBC wildlife cameraman Gordon Buchanan set up in the forest on the slopes of the volcano.
Among the other finds, scientist also list an “extremely hairy” caterpillar, at least 16 new species of frog – including the fanged example – 20 new varieties of insects and spiders and possibly a new species of bat.
