Biology     Glossary (e.g. epibenthic)

Clear coastal to outer reef slopes and drop-offs (Ref. 48636). Found around staghorn corals. The only member of the family with a crosshatch pattern of dark lines on the sides. Generally seen below 15 m depth and occurs singly or in pairs. Feed on small benthic invertebrates and algae, similar to C. mertensii (Ref. 37816). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 123201): 25.3 - 29, mean 28.1 °C (based on 394 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01159 - 0.04740), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.8   ±0.26 se; based on food items.
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).
Nutrients (Ref. 124155):  Calcium = 113 [58, 169] mg/100g ; Iron = 0.858 [0.517, 1.405] mg/100g ; Protein = 18.4 [17.2, 19.5] % ; Omega3 = 0.119 [0.073, 0.192] g/100g ; Selenium = 34.6 [19.2, 64.0] μg/100g ; VitaminA = 52 [14, 183] μg/100g ; Zinc = 1.65 [1.13, 2.34] mg/100g (wet weight);
