Gomphosus

Gomphosus is a genus of ray-finned fish belonging to the family Labridae, commonly known as wrasses. These are marine fish found in the Indo-Pacific region. The genus is characterized by its elongated, beak-like snout, which gives it its common name, the trumpetfish or cornetfish wrasse, although these common names are also used for other unrelated fish families.

Species within Gomphosus are typically found in coral reefs, often in shallow waters. They are solitary and diurnal, actively foraging during the day. Their diet consists mainly of small invertebrates and fish, which they extract from crevices and holes using their specialized snout. Gomphosus wrasses are known for their slender bodies and often vibrant coloration, which can vary between sexes and life stages.

The genus currently contains a few recognized species, with Gomphosus varius, the Pacific cornetfish wrasse, being one of the most widespread. They are generally considered to be of minor importance to commercial fisheries, though they can be kept in large public aquariums. Their distinctive morphology and behavior make them of interest to marine biologists and aquarium enthusiasts alike.
