Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 12; Rückenflossenweichstrahlen (insgesamt) : 9; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 6. This species is distinguished by the following characters: A II,6; dorsal-fin spines are rigid; relatively short snout, its length 12.3-17.2% (mean 15.1%) of SL, and is shorter than postorbital length; posterior margin of the maxilla reaching beyond vertical through middle of pupil; the distance between tips of lateral lacrimal and first suborbital spines is shorter than between tips of first and second suborbital spines; no supplemental preopercular spine; tentacles on supraocular and posterior lacrimal spines are well developed, their lengths greater than orbit diameter; trunk and fins with numerous tentacles; lateral lacrimal and suborbital spines poorly are developed, indistinct, usually tiny spines and often bony protuberances without pointed tips; without the distinct black blotch on soft-rayed portion of dorsal fin (Ref. 106976).
