Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 10; Anal spines: 0; Anal soft rays: 8 - 9. Distinguished from all Atlantic Canthigaster species (except C. supramacula) by the absence of longitudinal dark stripes on the side of the body or caudal peduncle. Distinguished from C. supramacula by the absence of a conspicuous dark spot on the dorsum (Ref. 43205).

Occurs in tide pools and to depths of up to 45 m (Ref. 43205). Also found in rocky areas to at least 50 m depth; adults often in pairs (Ref. 86997).

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=0.03631 (0.01554 - 0.08482), b=2.88 (2.69 - 3.07), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±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).
