Appearance
The scrawled cowfish has a thick, oblong body, which is largely enclosed in a thickened carapace with enlarged, plate-like hexagonal scales that are jointed with each other, the mouth, eyes, gills, fins, and the caudal peduncle. The bases of the dorsal and anal fins are completely encircled by the carapace. A pair of large spines projects over and beyond the eyes from each orbit. Another pair of spines occurs at each lower, rear corner of the carapace, and the isolated plate-like scales on the upper and lower caudal peduncle are also expanded into short spines. The small mouth has fleshy lips, and each jaw is equipped with fifteen moderately-sized conical teeth. The dorsal and anal fins both have ten soft rays.
