Actinopterygii (ray-finned fishes) > Tetraodontiformes
(Puffers and filefishes) > Balistidae
Etymology: Balistoides: Latin, balista, -ae = crossbowman + Greek, oides = similar (Ref. 45335). More on authors: Bloch & Schneider.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 50 m (Ref. 9770). Tropical; 35°N - 26°S, 32°E - 122°W
Indo-Pacific: Red Sea south to Delagoa Bay, Mozambique (Ref. 4420) and east to the Line and Tuamoto islands, north to southern Japan, south to New Caledonia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 75.0 cm TL male/unsexed; (Ref. 9710)
soft rays: 22 - 24. Fish has a deep grove before eye; scaleless area around lips, continuing and narrowing posterior to corner of mouth; small forward-curving spines in about five rows on side of and a short distance anterior to caudal peduncle. Caudal peduncle compressed (Ref. 9770).
Recorded from lagoons, seaward reefs (Ref. 1602) and sheltered inner reef slopes (Ref. 48637). Juveniles often associated with isolated patches of branching coral or rubble of shallow sandy protected areas. Adults occur singly or in pairs on the slopes of deep lagoon or seaward reefs (Ref. 37816, 48637). Often hostile towards divers and may attack unprovoked when caring for eggs (Ref. 48637). Feed on sea urchins, coral, crabs and other crustaceans, mollusks and tube worms. Oviparous (Ref. 205). Largest triggerfish; females are reported to have attacked divers when guarding their nest (Ref. 2334). Also caught with drive-in nets. Marketed fresh and dried-salted (Ref. 9770).
