Tropical Indo-Pacific


Long tube-like snout with a small barbel at the front of lower jaw, wedge-shaped tail without a filament, as on Fistularia species (Flutemouths). Occurs in two colour forms: Bright yellow, and grey-brown (more common). Grey-brown form usually has faint white stripes (sometimes more distinct), and a black area containing vertical lines of white spots preceding a yellow tail base banded with white. All markings can be more or less distinct. Swims slowly above reef.


Max Size: 80 cm

Sea Temperature Range: 19.9-30.8°C

Depth: 1-122m

Habitat Generalization Index: 19.83

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Frequent (18.1% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Few (2 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
