Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 3; Các vây lưng mềm (tổng cộng) : 24 - 27; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 19 - 24. Dark brown, scales with yellow spot; pectoral, soft dorsal, anal and caudal fins dark with yellow margins; juveniles yellowish brown with bluish grey spots and blotches (Ref. 4420). Juveniles under about 5 cm, tan with dark saddles and numerous dark wavy lines on the body. Larger juveniles loose the dark saddles and become covered in a network of brilliant blue lines which become increasingly interconnected with growth (Ref. 37816).

Sinh học     Tự điển (thí dụ epibenthic)

Occur in clear shallow lagoons and seaward reefs; sandy areas near reef patches of reef edge are preferred. Adults on deep reefs or with shipwrecks, usually deeper than 30 meters. Juveniles inshore on rubble reef or small outcrops on open substrate (Ref. 48637). Feed on sea urchins, crustaceans, mollusks, dead fish, tunicates or corals (Ref. 5503). Oviparous (Ref. 205). Monogamous (Ref. 52884). Also caught with drive-in nets. Marketed fresh and dried-salted (Ref. 9770).

Life cycle and mating behavior Maturities | Sự tái sinh sản | Spawnings | Egg(s) | Fecundities | Ấu trùng

Distinct pairing (Ref. 205). Nest-guarding females are aggressive (Ref. 9770). Females are territorial, solely tending and guarding the eggs. Males exhibit polygyny (Ref. 116451).
