Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 13 - 17; Rückenflossenweichstrahlen (insgesamt) : 8 - 11; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 15 - 20. Presence of a black head mask in males, a black streak on the caudal peduncle in both sexes, blackish dorsal fins in males, a plain whitish anal fin, a pointed snout (snout angle 30-40°), 16-21 anal fin rays, 15-20 + 15-20 lateral line scales, and 2-3 median mandibular pores.
Body shape (shape guide): elongated; Cross section: oval.
Adults are found on intertidal and subtidal areas, specifically on reef's surface, usually in weedy areas, on algal-covered rocks , or on rubble. They prefer silty habitat of upper regions, commonly on pylons, estuaries and harbors (Ref. 9002). They feed mainly on tiny invertebrates and algae (Ref. 2334). Eggs 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).
