Trumpetfish
Marine fish with a long tubular snout found in tropical reefs worldwide.
Trumpetfishes are three species of marine fish in the genus Aulostomus. They live in tropical waters and hunt small prey using suction from their tube-like mouths.
- Tube-shaped snout creates suction to catch prey
- Rigid body supported by interwoven bone struts
- Found in tropical reefs across Atlantic and Indo-Pacific
- Three living species in genus Aulostomus
- Occasionally kept in home aquariums
What it is
These fish belong to the genus Aulostomus within the family Aulostomidae. Their name comes from Greek words meaning flute and mouth, describing their long, tube-shaped snouts. They have rigid bodies supported by bony struts, similar to seahorses. The dorsal and anal fins sit close to the tail. Adults can reach nearly one metre in length. Their shape is elongated and pike-like. This structure helps them move through coral reefs.
Where it lives
Trumpetfishes inhabit tropical oceans across the globe. Two species live in the Atlantic Ocean, while one species occurs in the Indo-Pacific region. They are primarily demersal, meaning they stay near the bottom. They prefer reef environments. One species shows a preference for rocky substrates over sandy areas. These habitats provide cover and hunting grounds.
How it lives
They are carnivores that stalk small schooling reef fishes. Trumpetfish hover almost motionlessly just above the sea floor. When prey approaches, they dart forward quickly. They expand their jaws rapidly to create strong suction. This force draws the victim straight into their tubular mouth. Their inflexible bodies help maintain stability during these sudden movements.
Fish and people
There are no commercial fisheries targeting trumpetfish. However, they occasionally appear in the aquarium trade. They are not popular pets due to their specific needs. Despite this, guides exist online for keeping them in captivity. They hold little cultural or culinary value compared to other reef species.
