Description

The Bahaman cavefish is a blind cave fish of the livebearing brotula family, occurring only in dark inland caves, brackish sinkholes and marine blue holes of the Bahamas. The species grows to about 11 cm and has an elongate, pale to pinkish body; the eyes are reduced to vestigial remnants, as they are useless in the dark. It lives at shallow depth in cave water and is a livebearing carnivore. Because of its very limited, vulnerable range the species is listed as Vulnerable (VU) on the IUCN Red List.
