Scientific Name: Canthigaster bennetti
English Name: Bennett's sharpnose puffer
French Name: Bourse de sable
IUCN Red List Status: Least Concern (LC)
Dorsal spines: 0; Dorsal rays: 9-11; Anal spines: 0; Anal rays: 8-10.
A small sharpnose puffer with long conical snout and small terminal mouth. Body moderately compressed with short-based dorsal and anal fins.
Colour. Greenish to brownish upper body with whitish lower half. Large dark pale-edged spot around dorsal fin with electic blue line around base of fin giving ocellated
appearance to spot. The colouration of this species is variable depending upon the surrounding habitat. Often exhibits bluish greenish lines radiating from the eye and blue
lines on snout. Pale blue and orange spots on belly.
Maturity: Unknown. Max length : 10.0 cm TL.
Habitat and Ecology:
Inhabits inner reef flats and sheltered lagoons often on algal or silty reefs and associated sandy rubble areas (depth 1-15 m). Feeds mainly on filamentous green algae and to
a lesser extent on fleshy and coralline red algae and benthic invertebrates. Solitary or in groups. Oviparous. Forms monogamous pairs, although alternative mating systems have
been observed. Parental care is maternal and males and females maintain separate territories.
Single-species schools of over 10,000 individual C. bennetti have been observed off Sulawesi at depths of 7–30 m, accompanied by mass mortalities (Vail & Sinclair-Taylor 2011).
This species is not protected or subject to fishery regulations. It is not subject to fishery pressure.
