Etymology: Ogilbichthys: Named for the great Australian ichthyologist, J. Douglas Ogilby; kakuki: Named for Brian Kakuk, Caribbean Marine Research Center, Lee Stocking Island, Bahamas.
Eponymy: James Douglas Ogilby (1853–1925) was an Irish-born Australian ichthyologist and taxonomist, son of the famous zoologist William Ogilby (below). [...] Brian Kakuk was a US Navy Diver (1981–1988) who then moved to the Bahamas, where he is co-owner, Bahamas Underground Cave Diving Facility and Diving Safety Officer, Caribbean Marine Research Center, Lee Stocking Island, Bahamas.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 70 - 79; Anal soft rays: 53 - 61; Vertebrae: 40 - 42. This species is characterized by the following: outer pseudoclasper wing-like with distinct knob at tip of inner face, isthmus between pseudoclaspers narrower than base of penis; broad anterior inner pseudoclasper; scale band on cheek with 1 or 2 rows on lower cheek; otolith with separate colliculi (Ref. 55786).

Found in coral reefs, but has also been caught 230 mm inside an ocean blue hole in the Exuma Cays, Bahamas. The eye is not particularly small, indicating that it is not a very specialized cave species. A 6.1 cm SL female specimen caught from San Salvador Island contained 50 immature embryos (4 mm length) and 40 eggs between 0.2-0.4 mm in diameter (Ref. 55786).
