London, March 11 : Scientists have used DNA analysis to suggest that the “Dracula” fish lost its teeth about 50 million years ago, and developed rows of sharp protrusions that resemble teeth.
Dubbed the “Dracula” fish, the creature is about 17mm (0.7 inches) long and has been found in only one Burmese stream.
According to a report by BBC News, the researchers, from London’s Natural History Museum (NHM), believe the fish lost its teeth over evolutionary time, but later evolved the bone fangs.
