Short description Identification keys | Morphology | Morphometrics

Vertebrae: 40 - 42. This species is distinguished from its congeners by the following set of characters: presence of serrations on anterior edge of dorsal spine; thoracic adhesive apparatus not extending beyond base of last pectoral; total second dorsal-fin rays 9-12 (modally 11); total anal-fin rays usually 12-14 (modally 13); pectoral-fin rays 12-15 (modally 13); vertebrae 17 or 18 + 23 or 24 = 40-42 (usually 18 + 23 = 41); P-V 22·23, 23, 23·24, 24, 24·25 (usually 23·24, 24, 24·25); anteriormost anal-fin pterygiophore inserted behind 19-24th (usually 19-21st, modally 21st) vertebrae; uppermost 2-4 (modally 2-3) rays free on pectoral fin; 8-12 pectoral-fin rays branched (uppermost free rays and sometimes lowermost ray unbranched); AAA longer than half body depth at anus to anal-fin origin; dorsal-fin origin just above or behind anterior 1/3 of anal-fin base; pectoral-fin membrane not significantly concave between rays; pelvic fins united, forming a ventral disc; head length 13.9-20.8% of SL; P2A length 32.0-36.4% of SL; pre-pelvic-fin length 14.4-22.1% of SL; pre-dorsal-fin length 68.9-72.9% of SL; pre-anal-fin length 63.5-67.7% of SL; pelvic-fin length 2.8-4.7% of SL and 4.0-6.5% of pre-dorsal-fin length; greenish dark brown body when fresh; and post-flexion larvae lacking black lateral midline posteriorly on body (Ref. 138320).
Body shape (shape guide): elongated.

(Ref. 82804)
PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00708 (0.00335 - 0.01497), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278)
3.2   ±0.5 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179)
High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153)
Low vulnerability (10 of 100). 🛈
