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).

All markings can be more or less distinct. Swims slowly above reef.

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.
