What is a "pufferfish"?

A pufferfish, also known as a blowfish or fugu, is a unique and fascinating fish found in tropical and subtropical waters. It is characterized by its ability to inflate its body into a ball-like shape when threatened, increasing its size and deterring potential predators. Pufferfish have a distinctive appearance, with a round body, beak-like mouth, and spiky skin. Some species of pufferfish are known for their vibrant colors and intricate patterns. While they may seem cute and harmless, pufferfish actually possess a potent defense mechanism in the form of a toxic substance called tetrodotoxin, which is present in their organs, particularly the liver and ovaries. This toxin is highly poisonous and can be deadly to predators and even humans if consumed. Despite their toxicity, pufferfish are considered a delicacy in certain cuisines, but their preparation requires great skill and expertise to remove the toxic parts.
