Country

Bahamas

Types

Holotype: USNM 204603 adult male 109mm SL. Paratype: USNM 204604 female 76.5mm SL.

Distribution

Type locality: Mermaids Pool, New Providence Island, Bahamas (25o00’N, 77o30’W). Recorded also from other sites on New providence (Cohen and McCosker 1998; Attrill pers. comm.), Andros Island (Warner and Stroes‑Gascoyne 1981; Proudlove 1984), Berry Island (specimen UMMZ 213989), Long Island (specimen AMNH 57448), Exuma Island (Cohen and McCosker 1998) and Eleuthera (Moller, Schwarzhans, Iliffe and Nielsen 2006) (22-27oN, 72-80oW). (See also Palmer (1982), Farr and Palmer (1984:12) and Palmer (1986a,b)). Known only from locations on the Grand Bahama Bank (cf. Lucifuga lucayana which is known only from the Little Bahama Bank).

An individual from Swimming Hole, Congo Town, South Andros Island (TB 370750, also known as Jellyfish Lake) was noted to be 25cm in length and the largest ever observed (Palmer, Hutchinson, Schwabe and Whitaker 1998:100).

Habitat

This fish lives in anchialine caves (Iliffe 1992a; 2000) on several Bahamian Islands. Some of them (e.g. Mermaids Pool, Uncle Charlie’s Blue Hole) are typical inland holes of the cenote type, circular openings between 30 and 250m across and from 2 to 110m depth. They contain freshwater from the surface down to a mixing zone at variable depths and below this full strength sea water (Smart 1984). L. spelaeotes was collected in the freshwater zone of Uncle Charlie’s Blue Hole (Farr and Palmer 1984; Proudlove 1984), together with the grapsid crab Sesarma angustipes. One individual from this site was placed in a dish of sea water and appeared quite happy so it is possible that migration is possible within the extensive sea water filled passages. Other populations are known from typical marine Blue Holes (see e.g. Farr and Palmer 1984). These are subhorizontal passages, up to several km in length, which open beneath the sea and carry flows of freshwater from inland. A third habitat type, deep fracture oriented chasms, is seen on Grand Bahama (Palmer 1985; Cunliffe 1985).

Systematics

Placed in the subgenus Stygicola by Cohen and Robins (1970) because of the presence of palatine teeth and a pectoral fin ray count of 15-20. In the subfamily Brosmophycinae. This species cannot now consist of a panmictic population as its many populations are separated by impassable epigean sea water barriers. The morphological similarity of the animals may be as a result of lack of divergence from a once widespread ancestor (when the sea levels were lower and the Bahamian banks were much larger), or they are morphospecies.

(Dooley, J., Collette, B., Aiken, K.A., Marechal, J. & Pina Amargos, F. 2015. Lucifuga spelaeotes. The IUCN Red List of Threatened Species 2015: http://dx.doi.org/10.2305/IUCN.UK.2015-4.RLTS.T12398A19929465.en. Downloaded on 10 July 2017.

Some of these criteria relate to a decline in area of occupancy and/or quality of habitat (A1c) and the effects of pollutants, pathogens etc. (A1e). Others relate to a continuing decline in other  important habitat characteristics (B1+2bc). The D2 criterion is applied if the population is estimated as less than 1000, the area of occupancy is less than 100 km2 , or the number of recorded locations is less than 5. If the population of this species on New Providence is considered alone these criteria seem reasonable as the island is small and heavily populated. If the other populations on Grand Bahama, Abaco, Andros, Long Island and Berry Island are added these criteria cannot be supported. The habitats on the other islands are under much less pressure than those on New Providence and the area of occupancy is at least 30800 km2 (220 km x 140 km). Currently this species meets LC, the only subterranean species to do so. Barton and Wilmhoff (1996) record a number of introduced species of fishes on New Providence. These are a potential threat to all of the native fish fauna.
