Animal Species:Smooth Flutemouth, Fistularia commersonii Rüppell, 1838

The Smooth flutemouth is a very elongate fish that has a long filament projecting from the caudal fin. It occurs widely throughout the Indo-Pacific.

Standard Common Name

Smooth Flutemouth

Identification

The Smooth flutemouth is a very elongate fish that has a long filament projecting from the caudal fin. The filament is lined with sensory pores, and may serve as a long-range sensory system for detecting prey.

The species is usually greenish with blue wavy lines.

Two species of flutemouths are recorded from Australian waters, the Smooth Flutemouth and the Rough Flutemouth, F. petimba. The species can be differentiated by bony plates along the dorsal midline that are present in F. petimba but absent in F. commersonii and two ridges on the top of the snout that are parallel in F. petimba but bulge centrally in F. commersonii.

Size range

It grows to 1.6 m in length.

Distribution

The Smooth Flutemouth has a wide Indo-Pacific distribution. In Australia it is recorded from the south-western coast of Western Australia, around the north of the country and south to the central New South Wales coast.
