Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 13 - 21; Spine anali: 0; Raggi anali molli: 12 - 23. Resembles H. lossei, which is more slender and has small dark spots on the flank. Overlaps range of H. quadrimaculatus, which has elongate wing-like scales underneath the normal paired pre-dorsal scales. Flank silvery, without dark spots; a bright yellow or orange patch behind gill opening; dark blotch on tip of dorsal fin.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
A schooling species occurring in coastal waters. Caught with artisanal fishing gear (Ref. 30573).
