"Two specimens of Cheilodipterus affinis Poey from the Bahamas have darkly pigmented, fleshy, protuberant chin flaps. One of these was sectioned and compared histologically with the tip of the mandible from a specimen without the flap. The flap seems to be the result of an increased amount of loose, collagenous connective tissue and histologically bears a strong resemblance to the pharyngeal pads of the mouthbrooding cichlid, Geophagus jurupari. Ten additional specimens with chin flaps have been found in trawl collections made off the coast of Venezuela. This cardinalfish is an oral brooder: eggs have been found in the mouths of seven males and three females. Two of the females and all of the males with eggs in their mouths had chin flaps, but one female without a flap was carrying eggs"--P. 10.
