Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm SL male/unsexed; (Ref. 48637)
(total): 6 - 7;
soft rays: 10. Resembles C. leucostictus and C. maudae, but lacks dark bars dorsally.
Characterized by the following: brilliant white snout and back; brown color on most of head and body with variable-sized white spots; white spot on base of upper pectoral fin rays; basal part of lower pectoral fin with white spot or triangular marking; united pelvic fins, presence of frenum; longitudinal scale series 113-130; head without scales; greatest depth of body 5.9-6.3 in SL; rounded caudal fin, slightly longer than head (Ref. 90102).
Lives in silty sandy substrate with small boulders or large rubble pieces in few meters depth (Ref. 48637). Associated with snapping shrimp in their burrows.

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00330 - 0.01518), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
