The trumpetfish can be recognized by its long stick like body with a tubular snout and a chin barbel. Their coloration is variable ranging from yellow, grey and reddish brown. They have the ability to change color to match their surroundings. The dorsal fin is split into two parts, with a set of small spines mid body and a second dorsal fin set back very far above the anal fin which it matches in size. The body shape and configuration of the tail give it a surprisingly fast acceleration from a standstill. They grow up to 80 cm in length. The mouth is very elastic and is opened to create a vacuum to suck in prey. Males have a specialized pouch used to carry the eggs after mating.
