Description

The black-blotched porcupinefish is a porcupinefish of the family Diodontidae reaching about 65 cm. The brown body is covered with long, normally flat-lying spines and bears large, dark-edged blotches, plus a black band across the eyes. When threatened the fish pumps itself up with water into a ball, raising the spines erect and becoming too large and prickly for most predators. With its jaws fused into a strong beak it crushes shellfish, sea urchins, snails and crabs. The species lives near reefs and rocky bottoms of shallow coastal water in tropical seas worldwide. Like many puffers and porcupinefishes its skin and organs may contain the poison tetrodotoxin; it should not be eaten.
