Taxonomy

Balistoides was first propsed as a genus in 1935 by the English ichthyologist Alec Fraser-Brunner with Balistes viridescens designated as its type species. [2] B. viridescens had originally been described in 1801 by the German naturalists Marcus Elieser Bloch and Johann Gottlob Schneider with its type locality not given but is Mauritius, as the descruption was based on Bernard Germain de Lacépède's Baliste verdatre. [3] A 2016 study found that Balistoides was non-monophyletic with B. conspiciillum being sister to Balistapus and B. viridescens being sister to Pseudobalistes . However, the 2016 study stated the results concerning the "close association" of Balistapus undulatus and Balistoides conspicillum, were only "moderately supported" [4] and it has not resulted in the classification of the triggerfishes being changed. [1] This genus is classified in the family Balistidae, which is classified in the suborder Balistoidei in the order Tetraodontiformes. [5]

Etymology

Balistoides sufffixes -oides onto Balistes and means having the form of Balistes. [6]

Characteristics

Balistoides triggerfishes have a laterally compressed caudal peduncle. The scales above the base of the pectoral fin and the gillslit are very enlarged and form a flexinle tympanum. There is an obvious grrove on the snout in front of the eye. The teeth in the jaw are white and do not prominently project. Almost all of the cheek is covered on scales except for a very small fold at the corner of the mouth. The dirsal and ventral profiles if the head are concave, straight or slighly convex. The body is not plain black or very dark blue but is marked with different coloured blotches and lines. [7] The smallest of the two species in this genus is B. viridescens with a maximum total length of 75 cm (30 in) while the maximum published total length of B. conspicillum is 50 cm (20 in), [8]

Distribution and habitat

Balistoides triggerfishes are found in the Indian and Western Pacific Oceans from the eastern coast of Africa east as far as the Tuamotus and Line Islands, south to northern Autralia and north to southern Japan. [9] The two species in this genus are associated with coral reefs, at depsth down to 75 m (246 ft). [7]

Triggerfish are about 40 species of often brightly colored marine rey-finned fishes belonging to the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.
