Etymology: The plural "triggerfishes" is simply the plural of "triggerfish," which is what it is. "Triggerfish" is a compound of "trigger" and "fish," and the name is a description of the fish's most unusual feature. Its first sp-dorsal fin has a stiff spine that can be raised and locked upright, and it is released by pressing a smaller second spine, much as a trigger releases a mechanism. Anglers and naturalists saw that the first spine was the working part, and the name follows that image. The compound first appears in English in the 1840s, a late coinage that reflects the growing scientific description of tropical reef fishes in that period. The "fish" element goes back through Old English "fisċ" to a Proto-Germanic root, but the story here is the mechanical picture behind the name rather than that older lineage.

Synonyms: fish, marine fish, tropical fish, reef fish, aquatic fish
