The long-spine porcupinefish is pale in colour 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.
