Centriscus cristatus is the largest species of snipe knifefish (Centriscinae) and occurs in the tropical western Pacific on the coast of northern Australia.
features
It becomes a maximum of 30 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 main ray of the first dorsal fin is jointless and rigid, the most important characteristic of the genus Centriscus . Centriscus cristatus is light to whitish in color and has a yellow stripe on the flanks, which extends from the tip of the tweezer-like snout to the base of the second dorsal fin. Adult fish have a few blue bars on the back of their bodies.
Way of life
Centriscus cristatus lives near the coast near the sea floor, alone or in small groups in seagrass beds or estuaries . It feeds on small, planktonic crustaceans . Like all snipe knifefish, it swims upside down at an incline of 20 ° or more.
