Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal 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.

Biology     Glossary (e.g. epibenthic)

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. 123201): 25.4 - 29.3, mean 28.6 °C (based on 1810 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), 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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
