Description
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.
