threetooth puffer

The threetooth puffer, scientifically known as Triodon bursarius, is a unique species within the order Tetraodontiformes. This fish is characterized by its three fused teeth, forming a beaklike structure with a split in each jaw. While most puffers are found in warm seas, the threetooth puffer is a deep-water species inhabiting tropical Indo-Pacific oceans.12

Puffers, in general, are known for their ability to inflate themselves with air or water when threatened, becoming globular in shape. Many species of puffers, including some related to the threetooth puffer, contain a potent toxin called tetraodontoxin, particularly in their internal organs. Despite this toxicity, some puffers are prepared as food, notably in Japan, where they are known as fugu and require specialized preparation by trained chefs.21
