Moorish Idol Video Stock Footage
With distinctively compressed and disk-like bodies, Moorish idols stand out in contrasting bands of black, white, and yellow, which makes them attractive to aquarium keepers. The fish have relatively small fins, except for the dorsal fin, whose six or seven spines are dramatically elongated to form a trailing, sickle-shaped crest called the philomantis extension. Moorish idols have small terminal mouths at the end of long, tubular snouts many long bristle-like teeth line the mouth. The Moorish idol differs from butterflyfish in having a prominent black, triangular anal fin. The eyes are set high on the fish's deeply keeled body in adults, perceptible bumps are located above each. The anal fin may have two or three spines. Moorish idols reach a maximum length of 23 cm (9.1 in). The sickle-like dorsal spines shorten with age.
