It is distinguished from the
porcupinefish by the shorter, less sharply pointed, and immovable
spines which cover the somewhat
spherical body. It can inflate its body by taking either air or water into a
ventral extension of the
stomach. Its color is olivaceous or brownish above and pale yellow below. The back and sides are irregularly striped with brownish, dusky, or black lines which are parallel to each other and which run obliquely downward. There are several large black spots on the sides, one just below the dorsal fin, and another behind the
pectoral fin. Its maximum size is about 10 inches. ==Distribution==
