Centriscus scutatus ( Syn .: Amphisile scutata ) is a species from the family of snipe knife fish (Centriscinae) and occurs in the Red Sea , the Persian Gulf and the tropical Indo-Pacific as far as New Guinea, Australia and Japan.
features
It becomes a maximum of 15 cm long and has an elongated knife-shaped body with a sharp abdominal edge and dorsal fins offset far towards the end of the body. The soft-rayed second dorsal fin and the caudal fin are ventral . The first dorsal fin is supported by three spines, the second by ten to twelve soft rays. The anal fin has eleven to twelve soft rays. The main ray of the first dorsal fin is jointless and rigid, the most important characteristic of the genus Centriscus . Centriscus scutatus is silvery in color and has a reddish-brown to blackish stripe on the flanks, which extends from the tip of the tweezer-like snout to the base of the second dorsal fin. Young fish resemble an angular brown leaf.
Way of life
Centriscus scutatus lives in three to one hundred meters depth near the coast over sandy or muddy seabed, usually in large schools above 15 meters between branched corals, black corals and in shipwrecks. Young fish often hide between hair stars or the spines of sea urchins . It feeds on small, planktonic crustaceans . Like all snipe knife fish, it swims with a tilt of at least 20 ° or vertically with its head down.
