Description
The bluespotted cornetfish is a strikingly elongate reef fish of the cornetfish family (Fistulariidae) from the Indo-Pacific. The species grows to about 1.6 metres but is very thin, with a long, tubular snout and a thread-like extension of the tail fin. The body is greenish with rows of blue spots or lines. It inhabits a variety of reef habitats to at least 128 metres and also sand flats and seagrass. As a stalking predator it approaches prey slowly and then sucks up small fishes and shrimps at great speed with its tubular snout. The species has invaded the Mediterranean through the Suez Canal. It is harmless to humans.
