Male first dorsal fin slightly higher than second; slightly lower in females. Key features are: overall olive green; anal fins black and white barred. Males head black; first dorsal fin, lower pectoral-fin rays and proximal portion of the pelvic-fin rays yellow females (Ref. 57774, 88983).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Female members of the Tripterygiidae have eggs that are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
