Description
Eastern conterpart of the rough bullseye.

The species is abundant in caves on offshore reefs, with juveniles generally occurring in shallower water, particularly near the entrance to estuaries.

Rarity
  • IUCN Threat Status: Not Evaluated
  • Occurrence: Common (29% 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 (42 per transect)
    Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
