Dragonets

Fish - Marine

Dragonets are small, perciform, marine fish of the diverse family Callionymidae (from the Greek kallis, "beautiful" and onyma, "name"). Found mainly in the tropical waters of the western Indo-Pacific, the family contains approximately 186 species in 18 genera. The Draconettidae may be considered a sister family, whose members are very much alike, though rarely seen. Due to similarities in morphology and behaviour, dragonets are sometimes confused with members of the goby family.
