Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 3 - 58 m (Ref. 1602). Tropical; 36°N - 48°S, 24°E - 132°W
Indo-Pacific: Red Sea and East Africa eastward through Indonesia to Tuamotus, northward to southern Japan, southward to Lord Howe Island.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 120 cm TL male/unsexed; (Ref. 9710); common length : 54.0 cm TL male/unsexed; (Ref. 5450)
Relatively uncommon in patch reefs and coral slopes near sandy areas of clear lagoon and seaward reefs. Juveniles occur in sandy and weedy inner reefs, adults on clear lagoons and seaward reefs (Ref. 9710). Juveniles inshore, usually on muddy substrates and often estuarine. Adults on deep slopes and range to outer reefs, sometimes swimming high above the substrate or just below the surface. Pelagic larvae may disperse over great distance and juveniles occur in subtropical zone (Ref. 48637). Enter estuaries (Ref. 4833). Considered as the giant among puffers reaching a total length well in excess of a meter.
