Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 10; Radios blandos dorsales (total) : 11 - 12; Espinas anales: 3; Radios blandos anales: 11 - 12. Preorbital serrae 10-20; body depth 2.6-2.9 in SL; dorsal profile of head nearly straight; eye not very large, orbit diameter 3.0-3.45 in head length; caudal concavity 1.45-1.7 in head length; third anal fin spine longer than second; pelvic fin spine 2.3-2.9 in head length. Silvery with a coarse silver and black reticulum dorsally on head; posterior edge of caudal fin blackish (Ref. 41640).
Length at maturity about 18 cm. Taken with hook and line using bread or shrimp for bait (Ref. 44091). A native Hawaiian fish found in both marine and freshwater habitats. Feeds on fishes, invertebrates, and insects. Sr/Ca profiles from otoliths of juvenile and adult fish from fresh and salt water indicated that use of stream habitats by this species is facultative (Ref. 51353).
