KUALA LUMPUR: Wildlife researchers have discovered 123 new species on Borneo island, including a lungless frog, the world's longest insect and a slug that fires 'love darts' at its mate.
Conservation group WWF listed the new finds in a report on a remote area of dense, tropical rainforest that borders Malaysia, Indonesia and Brunei on Borneo.
The three governments in 2007 designated the 220,000-square-kilometre (88,000-square-mile) area as the "Heart of Borneo" in a bid to conserve the rainforest.
Frog that breathes through skin
"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," said Adam Tomasek, head of WWF's Heart of Borneo initiative.
The "Heart of Borneo" region is home to 10 species of primate, more than 350 birds, 150 reptiles and amphibians and about 10,000 plants that are not found anywhere else in the world, the report said.
Among the finds are a seven-centimetre (three-inch) flat-headed frog, known as the Barbourula kalimantanensis discovered in 2008 and which breathes entirely through its skin instead of lungs.
Love darts
Researchers in the same year also discovered Phobaeticus chani the world's longest stick insect that measures 56.7cm with a body 35.7 cm long. Only three specimens of the creature have ever been found.
Another interesting find was a long-tailed slug Ibycus rachelae that uses 'love darts' made of calcium carbonate to pierce and inject a hormone into a mate to increase the chances of reproduction.
"We know that it is impossible for the three governments not to have development in mining, oil palm plantations and logging in the area," Tomasek said.
"What we want to have is a balance so that we have a foundation of conservation and sustainable development in order to protect this unique site for future generations," he added.
