An Australian scientist has discovered a species of frog having tadpoles with black fangs in southern Vietnam, Australian Network News reported Thursday.

 

Dr. Jodi Rowley of the Australian Museum, who found the frog, said in the news source that it is the first time fangs have been discovered in a tadpole.

 

He said they are studying why the frog, nicknamed "vampire flying", has fangs.

 

“Maybe it’s got something to do with what they eat. They breed in very small pools of water in holes in the trunks of trees, so maybe they eat something particularly strange there,” Dr. Rowley said.
