Temperate Australasia


Closely resembles the eastern striped trumpeter, but has a smaller and more rounded head and three-pointed teeth. It also has five to eight stripes along the sides and a fully spotted tail. The species is very abundant in sheltered seagrass beds, consuming large quantities of algae growing on the seagrass as a major component of its diet.

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Infrequent (5.3% 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: Many (95 per transect)

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