Danger level
Harmless
Usual observation depth
3–30 m
Behaviour
Generally solitary or in pairs. An ambush predator moving slowly, it often adopts a head-down or vertical position among corals, gorgonians or sea pens, and may swim alongside large fish to conceal its approach from prey. Mainly active during the day.
Observation zones
Coral reef, rocky reef, reef slope, lagoon, seagrass bed edge and sheltered bay.
Diet
Mainly small fish, particularly elongated reef fish; it rapidly sucks in its prey with its tubular mouth.
Reproduction
Oviparous
Identification marks
Body very long and narrow; extremely elongated tubular snout with a small terminal mouth; small dorsal and anal fins set far back near the tail; often brown, greenish, yellow, or mottled, sometimes with light spots or lines. It may be observed suspended vertically, head down.
Similar species
It can be confused with other trumpetfish. The spotted trumpetfish (Aulostomus maculatus) lives in the Atlantic, while the Pacific trumpetfish (Aulostomus strigosus) lives in the eastern Pacific; geographic distribution is the most reliable criterion for divers.
Approach rules
Approach slowly without blocking its path or disturbing its hunting posture. Keep a respectful distance of at least 2 m, do not touch or pursue it, avoid flash or use it minimally, and never feed it.
Protection
Globally assessed as Least Concern on the IUCN Red List. It is not listed in the CITES Appendices. Comply with the rules specific to marine protected areas where applicable.
