Tag: Black-Spotted Porcupinefish (Diodon Hystrix)

The Black-Spotted Porcupinefish (Diodon Hystrix) is a reasonably common species in local waters, although due to its nocturnal feeding habits, it can be rather reclusive during daylight hours, which it spends resting under rocks/corals or inside rocky crevices.

Reaching a maximumlength of around 90cm, the Black-Spotted Porcupinefish is one of the larger members of the Tetraodontidae family. Its diet consists mainly of crustaceans, molluscs and sea urchins, all of which it crushes with its fused, plate-like jaws.

This species is simlar in appearance to the Black-Blotched Porcupinefish (Diodon Liturosus) which is also found locally, however it lacks the large dark blotches and has shorter protective spines.

It is distinguished by the numerous small black spots over its light brown body and fins, with the exception of the underside which is white.
