Cornetfish

Any of the roughly four species of extraordinarily long and slender gasterosteiform fishes that make up the genus Fistularia are cornetfish, often known as flutemouth. Beyond the forked tail fin at the posterior end of the body, a long filament projects forth from the end of the backbone. These holes in the filament, which is frequently as long as the fish's body, may help the fish identify prey. Together, the cornetfishes' bodies and filaments are measured; the biggest cornetfishes may reach lengths of 2 meters (6.6 feet).

In the Atlantic, Pacific, and Indian oceans' temperate and tropical nearshore marine environments, which are distinguished by soft bottoms like sand flats, coral reefs, and sea grasses, you can find them. The cornetfish is one of the lionfish's natural predators in these waters. By consuming the lionfish, they assist in reducing their number and hinder the growth of the poisonous fish. Cornetfish have large snouts and very lengthy bodies. They can detect the presence of prey because to the sensitivity of their long tail. They pursue their unwary prey before attacking them. Nearer to the ocean floor, where numerous lionfish frequently swim, cornetfish typically search for prey. Cornetfish also consume other tiny fish, crabs, and squid in addition to lionfish.
