Silvery to brassy, often with broken, diffuse brassy bands on back, or small dark spots. More rounded and deeper head than other Seriola species, with the deepest part of the body usually between the back of the head and the 1st spiny dorsal fin. The amberjacks S. rivoliana and S. dumerili are typically deepest bodied below the start of the 2nd (soft) dorsal fin, tapering more symmetrically.
Max Size: 150 cm
Sea Temperature Range: 15.9-24.5°C
Habitat: Coral Reef, Open ocean, Rocky Reef
Habitat Generalisation Index: 0.6
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). Learn more here
IUCN Threat Status: Not Evaluated
Occurrence: Infrequent (6% 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: Several (7 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
