Striped Burrfish

Fascinating facts about the Striped Burrfish

• The striped burrfish can inflate its body by taking air or water into a ventral extension of the stomach.
• Its back and sides are irregularly striped with brownish, dusky, or black lines that run obliquely downward, and it has several large black spots, one just below the dorsal fin and another behind the pectoral fin.
• It is found mostly in the tropics of the western Atlantic Ocean from Brazil to Florida, sometimes as far north as Cape Cod, and regularly during late summer and fall near New York.
• July turns New Jersey’s waters into a nursery when the striped burrfish releases its eggs, while juveniles drift into the Chesapeake Bay to grow during the summer months. These seasonal hotspots highlight the fish’s reliance on specific coastal habitats for each life stage.
• Despite having no commercial value, the fish sometimes lands on beaches as a treacherous surprise for barefoot walkers, and a few end up in home aquariums or as curios on shelves. Its accidental encounters remind us that even overlooked species can leave a lasting impression on people.

About the Striped Burrfish

The striped burrfish, Chilomycterus schoepfii, is a modestly sized member of the porcupinefish family Diodontidae, reaching about 10 inches in length. Its body is a near-spherical globe cloaked in short, immobile spines that are less sharply pointed than those of its porcupinefish cousins. A mottled olive-brown dorsal surface gives way to a pale yellow ventral side, while the back and flanks are etched with irregular, parallel brownish-black stripes that slope obliquely downward. Large black spots punctuate the sides, one just below the dorsal fin and another behind the pectoral fin, adding a striking contrast to its otherwise muted palette. When threatened, this fish can inflate its stomach ventrally, drawing in air or water to puff up like a living sea-urchin, a surprising defensive trick that deters predators and makes it a treacherous surprise for unsuspecting beachgoers stepping on the sand. Its range spans the tropical western Atlantic, from Brazil up the U.S. Atlantic coast to Florida, occasionally reaching as far north as Cape Cod and regularly appearing near New York in late summer and fall. Spawning occurs off New Jersey in July, and juveniles drift into the Chesapeake Bay during the warm months. The burrfish’s diet is a specialized buffet of hard-shelled invertebrates, oysters, barnacles, mussels, small crabs and hermit crabs, crushed by its powerful jaws. Though it holds no commercial fishery value, it is sometimes captured by anglers, stuffed as a curio, or briefly enters the aquarium trade before being discarded, illustrating its modest but curious place in human-marine interactions.
