Rough Triggerfish

Aspect:	Outline typical of triggerfish, with dorsal and anal fins set far back, which distinguishes it from filefish with which it is often confused.
Population:	Uncommon around Ilets Pigeon (see Environment), these samples having drifted from northern Guadeloupe under a patch of vegetal flotsam following a very strong storm.
Notable feature:	Base colour varies even within a single school from dark brown/purple to light beige, but with numerous bluish dots or short lines. Why Triggerfish? The name is owed to its peculiar mechanical defense system by which the dart it erects in lieu of forward dorsal fin is vertically locked in place by the second spine.
Environment:	Mangrove.
Behaviour:	Can easily be approached closely.
