Fish, diverse group of animals that live and breathe in water. All fishes are vertebrates (animals with backbones) with gills for breathing. Thefinding about fish and its history shows that about 15,000 new species are still discovered every year, from psychedelic fish to pink millipedes, and from lungless frogs to the Dracula fish. And, the strangest fish in my mind of all is : Dracula Fish.
It called dracula, must be for a certain reason. It has been reported in NewScientist, that Danionella dracula has been found. Danionella expert Ralf Britz of the Natural History Museum in London, mentioned, Dracula fish” is the only member of the 3700-strong Cypriniformes group to have vampire-like fangs on its top and bottom jaws, which the males use to impress each other and to settle squabbles over territory. With its teeth still exist, it looks like it really evolved something new. The Dracula fish’s DNA has been compared with that of zebrafish and other members of the family. And Britz estimates that the bony fangs evolved within 30 million years of the family losing its true teeth. Wow! This fact makes me really curious, how could this teeth still exist? What are these teeth made of?
