Aspect: Looks like a Cowfish (q.v.) at first sight, particularly those specimens boasting some of the latter's honeycomb pattern, but a close look reveals a) a larger size, b) no over-eye "horns", c) a very noticeable hump on the back, d) a longer tail fin root, and e) a dotted head and tail root (no lines there). Population: Less abundant than other box fishes. Notable feature: Prominent back hump. Environment: Around rock or coral boulders, relatively shallow waters (10 metres max). Behaviour: Difficult to approach closely.
