Etymology: Cryptocentrus:Greek, kryptos = hidden + Greek, kentron = sting (Ref. 45335); epakros:Name from Greel 'epakros' meaning pointed at the end; referring to the diagnostic anal fin
shape, consisting of elongated seventh and eighth fin rays that result in a conspicuous pointed posterior fin profile.
Ραχιαίες άκανθες (συνολικά) : 7; Μαλακές ραχιαίες ακτίνες (συνολικά) : 10; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 9. Dorsal-fin rays VI-I,10; anal-fin rays I,9; pectoral-fin rays 15; scales in longitudinal series 47; median predorsal scales 19; body scales entirely cycloid, including abdomen, and prepelvic region; pectoral-fin base and head naked except side of nape and predorsal region; preopercular-canal pore N absent; gill opening extending forward to a vertical at posterior edge of preopercle; seventh and eighth anal-fin rays prolonged, resulting in distinctly pointed posterior anal-fin profile; longest anal-fin rays 1.1 in HL; caudal fin rounded, longer than head, 3.1 in SL; pelvic fins relatively short, not reaching posteriorly to anus, 4.7 in SL; color of female generally golden brown with six faint dark bars from nape to caudal-fin base, interspersed with yellowish, slightly narrower interspaces; both dorsal fins with vertical, dark-edged orange markings between each spine and ray, interrupted to form spots on outer half of fin; second dorsal fin with pale blue submarginal stripe; anal fin dusky yellow brown, except posteriormost portion (encompassing last three rays) bright yellow; caudal fin is yellow to brownish with longitudinal blue streak between most rays of middle portion; pelvic-fin rays are dusky brownish; male (not collected, but presumed to be the same species) with 4 oblique and narrow orange bands (usually wavy and interrupted) on the cheek and opercle and have more vivid dark bars on body (Ref. 116711). Body shape (shape guide): elongated; Cross section: compressed.
The area of collection consists of moderately sloped (ca.20 degrees) mud substratum, where the slope begins in approximately 1.5 m depth and flattens out at about 18 m. The featureless bottom have numerous burrows occupied by a variety of fishes and invertebrates, including Cryptocentrus epakros. Three individuals (the female holotype, a presumed male, and another female) were observed in 12.5-15.0 m depth. Each individual was invariably associated with an unidentified alpheid shrimp (colour overall is pale greyish with bright pink legs and a pink claw with a bluish tip). The female holotype was in close proximity (about 30 cm) to the presumed male, which occupied a separate burrow (Ref. 116711).
