Vampyrius
Rhacophorus vampyrus (Vampyrius vampyrus) is a flying frog.  It lives in Vietnam.  It is the only frog species in its genus. People also call it the vampire tree frog or vampire flying frog. This is because the tadpoles have two black hooks in their mouths that look like vampire teeth. Its Vietnamese name is Ếch cây ma cà rồng.
