Etymology: Lucifuga: Latin, lux = light + latin, fugere = to escape, to avoid, to run away from (Ref. 45335);  lucayana: Named for its type locality, Lucayan Caverns, graveyard of the Lucayan Indians who inhabited the Bahamas for 2000 years and were eliminated by the European invaders..

Short description Morphology | Morphometrics

Dorsal soft rays (total): 84-91; Anal soft rays: 63 - 69; Vertebrae: 50 - 52. This species is distinguished from its congeners by the following combination of characters: Vertebrae 12-13+37-39=50-52, dorsal fin rays 84-91, anal fin rays 63-69, pectoral fin rays 17-18, caudal fin rays 10; head profile above eye strongly depressed, scales on occiput, eyes present (0.9-1.0 % SL); palatine teeth absent; color uniformly light brown, long gill-rakers 3, pale (Ref. 57878).

Biology     Glossary (e.g. epibenthic)

Found in an anchialine cave which is connected to the sea via a submerged passage which opens into a tidal saltwater creek. The upper about 14 m in the cave consists of freshwater (22 °C), separated from a lower, slightly warmer (23-25 °C), salty layer by a distinct halocline. The holotype was taken in a depth of 12 m, which must then most likely to be freshwater; some where collected from one or two inland sink holes (Ref. 57878).

Estimates based on models

Preferred temperature (Ref. 123201): 26.3 - 28, mean 27 °C (based on 198 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):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
