Rats as big as cats, fanged frogs and grunting fish - they sound like
something from a horror movie.
But, incredibly, there is a 'lost world' on a distant island where these
nightmarish creatures really exist.
A team of scientists discovered the animals - and dozens of others -
at a remote volcano in Papua New Guinea.

In the kilometre-deep crater of Mount Bosavi, they found a habitat
teeming with life which has evolved in isolation since the volcano last
erupted 200,000 years ago.
Among the new species was the the Bosavi Woolly Rat. One of the biggest rats
in the world, it measures just over 32 inches from nose to tail and weighs
3lb.
The silvery grey mammal has dense fur and its teeth suggest it has a largely
vegetarian diet and probably builds nests in tree hollows or underground.
The Bosavi Woolly was discovered by a team from the BBC's natural history
unit as they searched for new wildlife while filming the series Lost Land Of
The Volcano.
During the trip to a little-known part of the rain forest, the team also
found about 40 other new species, which are at various stages of
verification.
This included a marsupial called the Bosavi Silky Cuscus, a camouflaged
gecko, a fanged frog and a fish called the Henamo Grunter, which makes a
grunting sound from its swim bladder.

Researchers also found an extremely hairy caterpillar which is now
awaiting cataloguing in Oxford, where the team will give names to their
finds.
It is estimated that along with the giant rat and cuscus the expedition
found about 16 species of frogs, one species of gecko, at least three
species of fish, at least 20 of insects and spiders and possibly one new
species of bat.
The expedition was led by climber and naturalist Steve Backshall-wildlife
cameraman Gordon Buchanan and head scientist Dr George McGavin.
Mr Buchanan and Smithsonian biologist Dr Kristofer Helgen were first on the
scene when the rat was found by a tracker from the local Kasua tribe. Dr
Helgen said:
'This is one of the world's largest rats. It is a true rat, related to the
same kind you find in the city sewers, but a heck of a lot bigger.
'I had a cat and it was about the same size of this rat. This rat was
incredibly tame.
'It just sat next to me nibbling on a piece of leaf. It won't have seen a
human being before. The crater of Mount Bosavi really is the lost world.'

Hairy caterpillar found in the rainforest
Papua New Guinea is famous for the number and diversity of rodents that
live there, with more than 57 species from the Murid family of rats and mice
on the island.
Further evidence of the rich wildlife of the tropical location came with the
discovery of the Bosavi Silky Cuscus. This animal, which resembles a small
bear, is a marsupial that lives up in trees, feeding on fruits and leaves.
Weighing in at some 4.5lb, it has thick silky fur adapted for the mountain
environment in which it lives. Dr Helgen has identified it as a new
subspecies in the group of strange marsupials known as cuscuses.

He said: 'Long ago it was isolated on this volcano and has become
something unique to Bosavi.'
The habitat in the area is currently regarded as pristine, but less than 20
miles to the south of Mount Bosavi extensive logging operations are
happening.

The mountain acts like an island in the vast sea of jungle, trapping
different species on it.
The expedition base camp was in the foothills east of Mount Bosavi with
smaller teams going out to remote locations.
