Snout more rounded and body more elongate than other tropical snappers, light blue-green colouration blends well with open water, strongly forked tail with central notch and large teeth. Generally hovers near the edges of vision when approaching divers. Should not be eaten because of risk of ciguatera poisoning.

hard substrates within their range (generalists). Learn more here
IUCN Threat Status: Not Evaluated
Occurrence: Frequent (10% 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.
