Etymology: Canthigaster: Greek, kanthos = the outer or inner corner of the eye, where the lids meet, 1646 + Greek, gaster = stomach (Ref. 45335). More on authors: Allen & Randall.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 10 - 53 m (Ref. 37816). Tropical

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm SL male/unsexed; (Ref. 48637)
Inhabits invertebrate-rich inshore reef to outer reef walls where usually in caves in depths of about 25 meters or more. Found singly or in pairs and on one occasion a small groups was observed among plate-corals on soft bottom (Ref. 48637). Feeds on algae and small invertebrates (Ref. 89972). Moves fleetingly from one hole of the reef to the other. Very secretive.

Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 29, mean 28 °C (based on 344 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02818 (0.01190 - 0.06674), 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) .
