Short description 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=3.10 (2.88 - 3.32), 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. 69278): Very Low, minimum population doubling time more than 14 years (Assuming Fec < 10).

Vulnerability (Ref. 59153): Low vulnerability (22 of 100) .
