Morphology | Morphometrics
soft rays: 9. Resembles C. koumansi, but differs by having numerous small iridescent blue spots over a dark background with at least 8 transverse bars and 3 to 4 dark round spots longitudinally along the sides.
Common in fine sand or silt bottoms of shallow lagoons and coastal bays subject to terrestrial runoff at depths of 0.3 to 4 m. Uses the burrow of an alpheid species.

Estimates based on models
Preferred temperature (Ref. 115969
): 25.4 - 29.3, mean 28.6 °C (based on 1810 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00454 - 0.02011), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
