This fish was discovered in April 2007 in a river in Myanmar, Burma. Scientists believe that its features are "extraordinary" as one of the most interesting vertebrate discovered in recent decades.
Called Dracula Fish, this creature has only 17 mm in length and shows a sharp bony prominence, developed in the jaw bones that resembles some teeth.
Of the 3,700 species belonging to the order Cypriniformes, none shows teeth. Only males have these "teeth" that are used in territorial fights. This fish reach sexual maturity before they fully develop and because of that more than 40 bones are missing in comparison with its relative, the zebra fish, Danio Rerio.
