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

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.
