Large Napoleon wrasse — the males with their distinctive humped foreheads and fleshy lips — cruise the reef crest at Obyan singly or in pairs, investigating divers with a directness that reflects the absence of spearfishing pressure inside the MPA boundary. These animals can exceed 2 m in length and 190 kg, and a close encounter with one of the resident males at Obyan is one of the genuinely large-wildlife moments available in shallow tropical diving.
