Lizard-fish, also known as lizardfishes, are a primitive species of ray-finned fish found in tropical and temperate waters all over the world. They are easily recognizable by their long and slender body, large eyes, and wide mouths. Lizardfishes have a unique combination of features that make them well-suited to their environment, including an elongated body with a laterally flattened head, a wide and powerful mouth, and sharp teeth. These features allow them to move quickly and easily through the water and to search for food in the sand and mud. They also have a number of specialized organs that allow them to detect prey, including electroreceptors and chemosensory organs. The coloration of lizard-fish varies, but they are usually brown or green and have a dark stripe running along the back.
