The pufferfish is a unique marine creature known for its ability to inflate its body when threatened. This inflation is achieved by swallowing water or air, making the fish appear larger and more intimidating to predators. Pufferfish are found in warm coastal waters around the world and are recognized for their distinct spiny skin. In addition to their unusual defense mechanism, pufferfish contain a potent toxin called tetrodotoxin. This toxin is found in various parts of the fish and can be deadly to humans and other animals if ingested. Despite this danger, some cultures consider pufferfish a delicacy, requiring skilled preparation to ensure safety.
