About
Described in 2009 from streams in Myanmar, Danionella dracula made international headlines when scientists discovered males possess elongated canine-like teeth used in ritualised jaw-wrestling. Despite this, the fish is completely peaceful with anything it cannot fit in its tiny mouth. It is one of the most evolutionarily paedomorphic vertebrates studied.
