For those who have been sucked in by Twilight and True Blood, there’s a new breed of vampire to add to the list!

From the far jungles of Vietnam Rhacophorus vampyrus - the Vampire Flying Frog - has emerged as a strange new species of frog, recently discovered by Australian Museum scientist Dr Jodi Rowley, and colleagues.

This unusual frog has adapted for life in trees, using webbed fingers and toes for moving from great heights and gliding, hence the ‘flying frog’ name. But it’s the strange black ‘fangs’ the species’ tadpoles display which have earned it a place in the vampire world...

The new species is known only to inhabit a high-elevation area of forest in southern Vietnam, breeding in holes in trees.

“It’s pretty cool that these frogs have adapted to live in the trees so completely, even using water holes in trees to breed in and protect their offspring from all the predators that lurk in rivers and ponds,” comments Jodi.

“But the fanged tadpole - I’ve never seen anything like it before!”

In place of a normal set of mouthparts (usually similar to a beak), the tadpole of the Vampire Flying Frog has a pair of hard, black ‘fangs’ protruding from the underside of its mouth.

This new discovery is giving Jodi and her colleagues plenty to think about.

“This is the first time that ‘fangs’ have been recorded in a tadpole. We can only speculate at this stage what the fangs are for and we are now doing further research to look in to why the tadpoles have them,” says Jodi.

could it be that the tadpole sucks or scraps food particles from the tree?

As much as I'd like to say this species really lives up to its name, it is very unlikely indeed that the "fangs" are for sucking blood!

At present, we don't actually know what the "fangs" are used for, but we're working to figure it out.

The tadpoles live in very small pools of water that form in tree-holes (with a volume of water about the size of your fist). These small pools are unlikely to have much in the way of food, so the tadpoles may have fangs in order to eat something unusual. Some other species of frog with tree-hole dwelling tadpoles actually lay eggs in the tree-holes for the tadpoles to eat. Perhaps females of this species do the same, and the fangs help the tadpoles stab the eggs? Or maybe the fangs help the tadpoles stick onto the side of the tree-hole?

At this stage it's all just speculation. More to come!

This is quite interesting. Are the "fangs" for predation on visitors to the tree based water hole or to assist with transport i.e. clinging on to trees if they need to move. OR just for sucking the blood of an Englishman????
