Distribution of the long-spine porcupinefish

The long-spine porcupinefish (Diodon holocanthus), also known as the freckled porcupinefish, porcupine puffer, and porcupine pufferfish, is a species of marine fish in the family Diodontidae.

Description

Conventional and X-ray images of Diodon holocanthus

The long-spine porcupinefish is pale in color with large black blotches and smaller black spots; these spots becoming fewer in number with age. It has many long, two-rooted depressible spines particularly on its head. The teeth of the two jaws are fused into a parrot-like "beak". Adults may reach 50 cm (20 in) in length. The only other fish with which it might be confused is the black-blotched porcupinefish (Diodon liturosus), but it has much longer spines than that species.

Diet

The long-spine porcupine fish is an omnivore that feeds on mollusks, sea urchins, hermit crabs, snails, and crabs during its active phase at night. They use their beak combined with plates on the roof of their mouths to crush their prey such as mollusks and sea urchins that would otherwise be indigestible.

Distribution

The long-spine porcupinefish has a circumtropical distribution, being found in the tropical zones of major seas and oceans:
