Distribution

Tropical Indo-Pacific


Description

Males green with numerous stripes along the body, broken by a series of short bars on the back, and with yellow and black pectoral fin base. Females and juveniles with fine pinstripes, two ocelli on dorsal fin (which disappear with age), and one on upper tail base. Very common. Indian Ocean populations from western Indonesia to the Maldives considered a separate species (H. chrysotaenia), with spots on the tail of males, but this is not yet reflected in global databases.


Information

Conservation and Rarity

IUCN Status: Least Concern

Occurrence: Common (25.7% 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 (14 per transect)

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