Etymology: Canthigaster: Greek, kanthos = the outer or inner corner of the eye, where the lids meet, 1646 + Greek, gaster = stomach (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 16 m (Ref. 33390). Tropical; 30°N - 30°S
Indo-Pacific: East Africa to the Galapagos Islands, north to southern Japan and Hawaii, south to the Great Barrier Reef and the Society Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 4919)
Inhabit shallow water, often subjected to surge. Juveniles secretive and remain in holes of outer reef flat and reef margin (Ref. 37816). Adults on shallow reef flats in high energy zones to about 10 meters depth. Juveniles among small boulders (Ref. 48637). Benthopelagic (Ref. 58302). Feed mainly on algae, but also takes polychaetes, sea urchins, brittle stars, mollusks, tunicates, corals, crustaceans and sponges.
