Jungle secrets: 52 new species found in Borneo's 'Lost World'

More than 50 new species of animals and plants that have never been seen before have been discovered in a 'Lost World' on the island of Borneo in just 18 months, say scientists.

Among them are two tree frogs, a whole range of plants and trees and 30 brand new types of fish including a tiny one less than a centimetre long and a catfish with an adhesive belly that allows it to stick to rocks.
