Knowra Moorish idol Moorish idol The Moorish idol (Zanclus cornutus) is a tropical marine fish recognized by its disc-shaped body, bold black-and-white bands, and elongated dorsal-fin streamer.
Zanclus cornutus : The sole living species in the genus Zanclus, a reef fish with a tall, compressed body and long dorsal streamer. This is the Moorish idol's scientific species name.
Spongivory : A feeding strategy in which an animal eats sponges. Sponges form a substantial part of the Moorish idol's diet.
Recreational diving : Underwater activity undertaken for exploration, observation, or leisure rather than commercial work. Divers commonly encounter Moorish idols while observing tropical reefs.
Bannerfish : Reef fishes in the genus Heniochus, many of which have banded bodies and elongated dorsal fins. Bannerfish resemble Moorish idols but belong to a different genus and family.
Acanthuriformes : An order of ray-finned fishes that includes surgeonfishes, rabbitfishes, and the Moorish idol. The Moorish idol belongs to this broader fish order.
Coral polyps : Small individual animals that build coral colonies by secreting calcium carbonate skeletons. Moorish idols also pick at coral polyps while feeding on reef surfaces.
Marine aquarium : An aquarium designed to maintain saltwater organisms and their marine environment. The species is sought for display, but its specialized diet makes long-term care difficult.
Surgeonfish : Reef fishes in the family Acanthuridae, typically bearing a sharp blade near the tail base. Surgeonfishes are close relatives, but their tail spines distinguish them from the idol.
Dorsal fin : A fin along the back of a fish that helps stabilize movement and can serve other functions. The Moorish idol's conspicuous streamer is an extended part of this fin.
Foraging : The behaviors animals use to find and obtain food. The fish searches reef surfaces for sponges and other small food items.
