The bandtail puffer (Sphoeroides spengleri) is a species of pufferfish found in the western Atlantic Ocean, including the coastal waters of the Caribbean, Gulf of Mexico, and southeastern United States. Like other pufferfish, it has the ability to inflate its body as a defense mechanism and contains toxic compounds that make it dangerous to predators and humans if consumed.
