The harlequin sweetlips can be found along the reefs of Singapore’s Pulau Hantu. Juveniles, like the one in this video, are brown with large white blotches and mimic the movement of a poisonous flatworm for defence against predators. They gain more spots and the spots reverse from white to black as they age. It spends its life in the coral reefs and feeds on crustaceans, mollusks and other fish.
