Aulostomus

The family Aulostomidae is a monogeneric family of highly specialized, tubular-elongated marine fishes commonly known as trumpetfishes. Aulostomids belong to the order Syngnathiformes, along with the seahorses and the similarly built cornetfishes. Three distinct species of the family's sole genus, Aulostomus, are described.[1][2]

The name "Aulostomidae" is a composite of two Greek words: aulos, meaning flute, and stoma, meaning mouth, because the species appear to have tubular snouts.[1] "Flutemouth" is another less-common name for the members of the family (although this word is more often used to refer to closely related cornetfishes of the family Fistulariidae).

Trumpetfishes are found in tropical waters worldwide, with two species in the Atlantic and one in the Indo-Pacific. They are mostly demersal reef-dwellers, where one species seems to prefer rocky substrate.

They are relatively large for reef fish, where they reach almost 1 m in length. Bodies of trumpetfish are elongated, rigid, and pike-shaped.[3] Their dorsal and anal fins are almost closely adjacent to the tail, where individual dorsal spines reach midway towards the head region. Similar to most members of the order Syngnathiformes, the bodies of trumpetfish are inflexible, supported by interwoven struts of bone. A distinct trait of the family is their long, tubular snouts ending with somewhat nondescript jaws. Members of the family have the capability to expand their jaws quickly into a circular, gaping hole almost to the body's diameter when feeding.

Aulostomids are highly carnivorous fish. They stalk[3] their prey by hovering almost motionlessly a few inches above the substrate, inching their way towards unsuspecting prey. Once close enough, they rapidly dart in and expand their jaws rapidly. Opening their tube-like mouths in quick succession creates a strong suction force, which draws prey straight into the mouth. Aulostomids are known to feed almost exclusively on small, schooling reef fishes.[4]

While they have no commercial fisheries value, members of the family have been known to occasionally be found in the aquarium trade. Not popular aquarium fish, they are common enough with websites having instructions in keeping them in captivity.[5]

Species[edit]

Currently, three species in this genus are recognized:[6]
