Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 11 - 12; Dorsale zachte stralen (totaal): 10-12; Anale stekels 3; Anale zachte stralen: 8 - 9. This species is distinguished from all its congeners by the following characters: scale rows between fifth dorsal-fin spine base and lateral line 3.5; front edge of dorsal scaly area on head slightly convex, with small scales (fewer than 20) anteriorly; pored lateral-line scales 42-44; second anal-fin spine (2AS) longer than third anal-fin spine (3AS), 2AS/3AS ratio 1.23-1.50 (mean 1.36); strongly curved concavity on ventral edge of first two infraorbitals above rear end of maxilla, particularly obvious in specimens more than 13 cm SL; scales on preopercle flange absent; anal-fin membrane dark; molariform teeth strongly developed along both jaws, teeth rows strongly curved laterally at rear of lower jaw (Ref. 83673).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Feeds on invertebrates, including worms, mollusks, crustaceans and echinoderms (Ref. 5213), and small fish (Ref. 3670). Protandrous hermaphrodite (Ref. 55367). The flesh is excellent.
