Morphology | Morphometrics
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. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02818 (0.01196 - 0.06644), b=2.94 (2.73 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.4 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 (10 of 100) .
