'Devil face fish' bared milk teeth

Scientists have discovered a strange fish with bone fangs. After a period of research, they still have not rated them of any family but still put them in the list of ' unclaimed '.

Researchers at London's Museum of Self-History say that this fish lost its teeth during evolution and later grew fangs with bones. Male fish often use fangs to bite each other. They widened their jaws to their fullest extent, rushing to each other ' to lose enough ' but never saw them injured or bleeding.

Dr. Britz, who worked in Myanmar for more than a decade to name this bizarre fish, is Danionella dracula from the demon legend using a blood-sucking fang, named Dracula.

Unusual things in demon fish

The tiny fish were brought to England, delivered to the Fish Museum, which was initially misclassified into the same species. Dr Britz told the BBC's correspondent: ' After a year of living there, they began to die. When I made a specimen template, under a microscope, I exclaimed: Oh my God, their teeth '.

" Observe carefully, dyeing bones and cartilage into different colors and using yeast to dissolve all the meat, I find it clear they are not teeth ."

Instead of the jaw bone is a row of raised, sharp, cartilage cartilage, like teeth, with the same purpose and in the male fish, there are strange fangs.

Using DNA analysis data to establish newly discovered fish species in genealogy, the researchers believe that the teeth of this fish have degenerated from 50 million years ago.

Compared to similar species, they have a strange trait that achieves sexual maturity before the body fully develops. Dracula has fewer fish than its cousin Danio rerio zebrafish 44 bones and these bones grow late in the life of zebrafish.

Scientists are not in a hurry to put Dracula devil fish into a new species and let small fish with fangs swim in the pool with other ' strange ' fish that do not have a 'background '. Thus, the fish caught from Myanmar still belong to ' unclaimed ' species.
