Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 86 - 109; Anal soft rays: 66 - 82; Vertebrae: 51 - 55. This species is distinguished from its congeners by the following combination of characters: Vertebrae 13-14+38-42=51-55, dorsal fin rays 86-109, anal fin rays 66-82, pectoral fin rays 17-20, caudal fin rays 10; head profile above eye is strongly depressed, small, developed eyes 0.7-1.8 % SL; palatine teeth present, in 1-7 short irregular rows, with 3-56 teeth total; long gill-rakers 3, dark pigmented (Ref. 57878).

Inhabits dark inland caves, brackishwater sinkholes, and marine blue holes (Ref. 27158. 57878).

Estimates based on models

Preferred temperature (Ref. 123201): 26.1 - 26.9, mean 26.7 °C (based on 39 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Assuming Fec < 10).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
