Aulostomus chinensis
The trumpetfish is a skinny, elongated species that thrives in coral reefs across the equatorial belt: from the Pacific, the Australian coast, the Hawaiian Islands and all the way to Panama and of course our pristine coral gardens in Dumaguete. This stalking predator can lie motionless, usually with its head pointed below, blending with sea grass or algae strands. They use their coloration to blend in with their surroundings, hovering stealthily over their intended prey and sucking them through their long, prominent snout. The trumpet fish can reach lengths of up to 80 cm though individuals commonly seen are only 60 cm long.

Found from about 3 to 122 meters, their coloration varies, depending on their environment. There are three main color schemes: brown to green, mottled brown to green, and yellow. Individual trumpetfishes can change their color in order to further blend in with their surroundings. A black spot can sometimes be found on the base of their pelvic fins. A black stripe running throughout the length of the fish’s body can also be seen in some individuals. Eye-spots can also be seen on the fish’s tail fin, acting as a deceptive coloration mechanism to draw attention away from the fish’s actual mouth and head. Their chin holds a series of protuberances, called barbels, which they use to detect prey movement.
Usually solitary, trumpetfish hovers slowly on top of their intended prey. They use their tiny anal and pelvic fins to control their movements, making them almost imperceptible against the environment. Their coloration and lack of quick movement allows them to approach their prey, usually smaller fishes and crustaceans, undetected. As they hover vertically above their prey, they suddenly dart downward, using their long snout and small but flaring mouth to suck in the unfortunate fish. The trumpetfish achieves this suction effect by suddenly expanding their mouth and drawing their prey in. They have also been known to utilize other, slow-moving fish species, trailing in their wake or blending in with their patterns in order to approach its prey.
The trumpetfish is part of the Syngnathiformes, an order containing other elongated and oddly-shaped fish species like the pipefish and the seahorse. Like other members of this order, the Trumpetfish conducts an elaborate courtship dance prior to reproduction.
Approach them with as little movement as possible and you can watch them hunting their prey.
