Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 100 - 105; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 71 - 84. SL to 18 cm.
Body shape (shape guide): elongated.
Inhabit shallow reefs (Ref. 1602). Benthic (Ref. 58302). Uncommon species (Ref. 34024). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Mature at 46 cm SL (Ref. 34024). Size of 18 cm SL given by Ref. 37816 seems in error.
