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 when it has continued to disperse and is now well-established in some areas. This species is considered as part of the Lessepsian migration.
