Comprehensive Description

Description

  Common names: cornetfish (English), corneta (Espanol), pez-corneta (Espanol)
 
Fistularia commersonii Rüppell, 1838


Reef cornetfish,     Blue-spotted cornetfish



Extremely elongate, depressed body; a very long tubular snout with a short oblique mouth at the end;  snout and jaws relatively robust; space between eyes narrow (< 6.3% of snout length), with longitudinal ridges; minute teeth; no fin spines; dorsal fin sickle-shaped, at rear of body directly over the anal fin, which has same shape; dorsal 15-17, anal 14-16; pectoral rays 15 (rarely 13-14); pelvics on abdomen, well behind pectorals; a forked tail fin with a long central filament; body of juveniles covered with small spines; adults of some species with a row of bony plates in front of dorsal and anal fins; lateral line arched at front half of body, continues out onto tail filament. 


Greenish dorsally, shading to silvery white below, with two blue stripes or rows of blue spots on back; tail filament white.


Size: reaches 160 cm.

Habitat: a free-swimming fish often seen over reefs and seaweed beds; it can quickly assume a dark-barred pattern when close to the bottom.

Depth: 0-130 m.

Indo-Pacific in distribution; southern Baja and the Gulf of California to the northern Peru and the oceanic islands.

Biology

Adults inhabit reef habitats to a depth of at least 128 m, except in heavy surge areas. Also found in sandy bottoms adjacent to reef areas (Ref. 36710), either solitary or in schools (Ref. 9710). Benthopelagic (Ref. 58302). Feed on small fishes, crustaceans (squids and shrimps) (Ref. 36327, 36710) and squids (Ref. 37816). Probably marketed fresh, salted or dried or smoked but more often reduced to fish meal (Ref. 9301).

Bluespotted cornetfish

The bluespotted cornetfish, smooth cornetfish, or smooth flutemouth, Fistularia commersonii, is a marine fish which belongs to the family Fistulariidae. This very long and slender reef-dweller belongs to the same order as the pipefishes and seahorses, called Syngnathiformes. It is widespread in the tropical and sub-tropical waters of the Indo-Pacific, including the Red Sea. In 2000 its presence was reported in the Mediterranean Sea, since then it has continued to disperse and is now well-established in some areas.[2] This species is considered as part of the Lessepsian migration.[3]

The fish is of minor importance commercially, mostly being sold as fish meal but also fresh and preserved.[2] It is also sold as an aquarium fish.

Morphology[edit]

The bluespotted cornetfish is notable for its unusually long, slender body shape.[2] It has a tubular snout, large eyes and a long tail filament lined with sensory pores which may help with detecting prey. Its body is greenish-grey to brown with two thin blue stripes or lines of dots on the back and lighter on the front.

It grows to a length of 1.6 m (5.2 ft), but the average is around 1 m (3.3 ft). [4]

Biology[edit]

The bluespotted cornetfish is usually a solitary predator, stalking and feeding on small fishes, crustaceans and squid.[2] Sometimes they feed in small groups along the bottom on small bottom-dwelling fish which their long snouts are very efficient at sucking up.

Reproduction is oviparous- the large eggs hatch and develop outside of the body. Larvae hatch at 6-7mm.
