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.
It is found mostly in the tropics of the western Atlantic Ocean from the West Indies to Florida, and is found along the Atlantic coast of North America, sometimes as far north as Cape Cod, and regularly during the late summer and fall in the vicinity of New York. One has been reported caught on dead shrimp as far as Oyster Lake, near Matagorda Bay, Tx.
It has no commercial value but is occasionally taken by fishermen and stuffed as curio. Some end up in the aquarium pet trade. It occasionally is killed in gill nets and then tossed back by the fishermen. It is often washed ashore along the beach and is a treacherous object if stepped on by mistake with bare feet. Other species of burr and porcupinefish are found in the tropics.
