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.
Xanthichthys mento, the redtail triggerfish, blue-throat triggerfish, or crosshatch triggerfish, is a species of triggerfish from the Pacific.It inhabits outer-reef areas at depths of 6–131 m (20–430 ft), and feeds on zooplankton. [1]

Redtoothed triggerfish are normally deep purple with bluish-green markings on their heads and glowing light blue margins on the tail lobes and fins. Just like other fish in the family Balistidae, the tail is lyre-shaped. The mouth of the triggerfish seems to be grinning and it maintains tiny red teeth that are needle-sharp with two teeth in the ...
The grey triggerfish (Balistes capriscus), or gray triggerfish, is a species of ray-finned fish in the triggerfish family Balistidae, the triggerfishes. The species is native to shallow parts of the western Atlantic from Nova Scotia to Argentina and also the eastern Atlantic, the Mediterranean Sea and off Angola on the west coast of Africa.
Xanthichthys caeruleolineatus, the outrigger triggerfish is a species of triggerfish from the Indo-West Pacific. It occasionally makes its way into the aquarium trade. It grows to a size of 35 cm (14 in) in length.
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.
