Description

Hardenberg's burrfish is a porcupinefish (Diodontidae) from shallow coastal and reef water of the Indo-West Pacific. The species grows to about 25 cm and has a stocky, yellow-brown body set with short, fixed spines; when threatened it inflates with water into a spiny ball. With a strong, beak-like jaw it crushes shellfish, crabs and sea urchins. Its skin and organs contain toxic tetrodotoxin; the fish must not be eaten.
