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 - 30 m (Ref. 1602). Tropical; 32°N - 32°S
Indo-Pacific: East Africa south to Transkei, South Africa (Ref. 4919) and east to the Line, Marquesan, and Oeno islands, north to southern Japan, south to Lord Howe Island. Replaced by Canthigaster jactator in the Hawaiian Islands and Canthigaster punctatissimus in the tropical eastern Pacific (Ref. 37816). Also recorded from Southeast Atlantic.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 4919)
Occurs in clear lagoon and seaward reefs, Ref. 48637. Found with sponges at various depths (Ref. 48637). Prefers sheltered areas in the form of holes in dead and living corals. Solitary or paired. Feeds on sponges, polychaetes, filamentous algae and on smaller quantities of tunicates, crustaceans, echinoderms and corals.
