Less steep head than S. hippos (Samsonfish) and deeper body than S. lalandi (Yellowtail Kingfish), dark oblique stripe passing from mouth through eye to front of dorsal fin. Proportionally longer dorsal and anal fin lobes than the very similar S. dumerili (Amberjack), with dorsal fin lobe at least 1.3 (to 1.6) times the length of the pectoral fin. Approach divers with one or two passes. Rarely seen on hotter reefs toward the equator, where they inhabitat deeper depths.


Max Size: 160 cm

Sea Temperature Range: 18.4-30°C

Depth: 5-160m

Habitat Generalization Index: 5.46

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Infrequent (4.7% 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: Few (4 per transect)

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