Distribution

Temperate Australasia


Description

Colourful species with blue, green, black and yellow markings on the head and body, and characteristic horseshoe-shaped marks on the sides. It often co-occurs on reefs with the yellowstriped leatherjacket in the east and the bluelined leatherjacket in the west. Horseshoe leatherjackets are inquisitive and regularly swim up to divers; however, if threatened they retreat into caves.

Juveniles may completely lack the dark markings - see photo. Confirm ID by shape, presence of skin filaments, location and presence of adults.

Conservation and Rarity

IUCN Status: Least Concern

Occurrence: Common (42.9% 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 (3 per transect)

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