Recovering teeth
The fish of the Cyprinidae family lost their teeth 50 million years ago, but the species Danionella dracula has recovered. The males of this species have structures in the form of pointed blades. They are made of bone gag and without pulp or enamels. They are not real teeth, but they perform their function. They also have two incredible tusks they use to fight, hence the name of dracula. The species described on 11 March in the journal Proceedings of the Royal Society is 16 millimeters long and lives in a small stream in northern Myanmar.
