The triggerfish family, Balistidae. was first proposed in 1810 by the French polymath Constantine Samuel Rafinesque. [4] The closest relantives to the triggerfishes are the filefishses belonging to the family Monacanthidae and these two families are sometimes classified together in the suborder Balistoidei, for example in the 5th edition of Fishes of the World.

The queen triggerfish feeds on a variety of prey items, mainly on sea urchins, crabs and chitons, but also occasionally preys on shrimps, snails, bivalves, small fishes and brittle stars. [11] When feeding, it generally repeatedly bites the victim in order to crush its shell or detach it from the reef by sharp incisors.
Triggerfish are thought to have low swimming maneuvers to compensate for such behavior there are morphological adaptations. These fish have thick skin to aid in predation evasion. While swimming at low speeds their flexibility in dorsal and anal fins makes it capable for them to exhibit balistiform locomotion.
