FAQ
Frequently Asked Questions
They are closely related. All burrfish are pufferfish (order Tetraodontiformes), but not all pufferfish are burrfish. Burrfish belong to the family Diodontidae and are characterized by long, fixed spines.
Like many pufferfish, burrfish often contain tetrodotoxin, a potent neurotoxin, in their internal organs. This makes them dangerous to eat.
They are typically found in tropical and subtropical coastal waters around the world, including the Atlantic Ocean and the Caribbean Sea.
It is possible but challenging. They require large, specialised aquariums, careful water management, and a specific diet. Their toxin also presents a handling risk.
