Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 15 - 16; Dorsal soft rays (total): 8 - 10; Anal spines: 3; Anal soft rays: 7 - 8. Diagnosis: lachrymal plus four tubular infraorbitals; slight gap between third and fourth tubular infraorbital; snout acutely pointed, soft dorsal and anal fins, and caudal fin maculae often present but not usually forming distinct vertical bands on caudal fin; body depth 27.0-36.0% SL; caudal peduncle length 94.6-114.0% of width; tips of anterior pelvic rays of mature females jet black; dorsal, anal and caudal fin maculae present only in males, fins immaculate in females (Ref. 81260).

Monogamous, biparental, substrate spawner displaying some degree of sexual dichromatism (Ref. 81260). Pair-bonding, cave spawner (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 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).
