Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8. This specie is distinguished from its congeners (except Cabillus caudimacula) by possessing a pair of modified scales with enlarged ctenii at the base of the caudal fin; it differs from C. caudimacula in having: 5 predorsal scales in adults (vs. predorsal scales none in C. caudimacula); prepelvic area with cycloid scales (vs. naked); ctenioid scale area on side of body extending anteriorly to a vertical through base of third ray of second dorsal fin (vs. extending to a vertical through midbase of first dorsal fin); a narrow black transverse bar at base of caudal fin (vs. a distinctive, large dark blotch posteriorly on side of caudal peduncle and extending onto base of caudal fin); a prominent black submarginal spot at fin membrane between first and third spines of first dorsal fin (vs. no prominent black spot); gill rakers 1-2?4-5 (vs. 1-2?2-3) (Ref. 94253).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.3 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).
