👉 The fish weapon, also known as the dorsal fin or tail fin, is a specialized structure used by some fish for defense and predation. It's typically a sharp, elongated fin located on the back or tail that can be used to deter predators by making the fish appear larger or more threatening. In some species, the fin can also be used to stab or pin opponents, as seen in the case of the anglerfish, which has a modified dorsal fin that acts like a lure and can also function as a weapon to capture prey or defend against threats.
