Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 15; Rückenflossenweichstrahlen (insgesamt) : 9 - 11; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 16 - 18. This species is distinguished by the following set of characters: D2 XI or XII (modally 12); D2 9-11; A I,16-18 (7); pectoral fin-rays ii–iv (iii) + 4–6 (5) + vi–vii (vii) = 14–16 (iii + 5 + vii = 15 in holotype and 4 paratypes, iv + 4 + vii = 15 in 2 paratypes, iv + 5 + vii = 16 and ii + 6 + vi = 14 in single paratype specimen and non-type specimen); pored lateral-line scales 12 or 13; notched lateral-line scales 19-22; scales rows in longitudinal series 31-34; scales above 1st pored lateral-line scale 2 or 2½; scales below 1st notched lateral-line scale 3 or 3½ ; circumpeduncular scales 8; mandibular pores 3-4 + 1-2 + 3-4 (usually 3 + 2 + 3; 3 + 2 + 3 in holotype, 6 paratypes, and a non-type specimen, 3 + 1 + 3 and 4 + 2 + 4 in single paratype only); head relatively long, its length 29.2-32.5% (mean 30.6%) of SL; upper jaw length 9.2-11.7% (11.0%) of SL; first spine of first dorsal fin slightly longer than that of second dorsal fin, its length 10.8-17.9% (13.9%) of SL; anterior nostril tentacle unbranched; orbital tentacle circular, the edge slightly pointed, its length slightly less than or subequal to pupil diameter, Colouration: body generally yellowish or brownish with 6 or 7 bands, darker around lateral line; brownish blotches on each of pectoral-fin ray, forming 3 or 4 narrow bands; anal fin with 7-9 (Ref. 138615).
Body shape (shape guide): elongated; Cross section: oval.
Adults occur in shallow tidal pools, and seems to be associated with coralline rock and seagrass (Ref. 13227). 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).
