New species discovered in Borneo

A 'Ninja slug', a lungless frog and a giant stick insect are just some of the amazing new species discovered on the Borneo island.

Around 120 species have been found in an area designated for conservation and the findings have been published in a report by the WWF.

Among the findings are a long-tailed slug (pictured above) that uses 'love darts' made of calcium carbonate to pierce and inject a hormone into a mate to increase the chances of reproduction.

Researchers also discovered a 57 centimetre long stick insect named "Phobaeticus chani" (pictured left) and a flat-headed frog, known as "Barbourula kalimantanensis" (pictured right), which breathes entirely through it's skin instead of it's lungs.

Adam Tomasek, head of WWF's Heart of Borneo initiative, said "we have been finding on average three new species a month and about 123 over the last three years, with at least 600 new species found in the last 15 years."
