Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 21 - 23; Anal spines: 3; Anal soft rays: 19.

Common in shallow waters. Usually observed in pairs or large groups. Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205). Called a cunning fish since it can nibble the bait from a hook without taking the hook into its mouth. The juvenile Thalassoma sanctaehelenae has been observed cleaning the cunningfish of its parasites (Ref. 5288).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

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

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01133 - 0.04632), 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): 3.3 ±0.6 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).

Price category (Ref. 80766): Unknown.
