For ten points, name these aquatic animals, examples of which include piranhas and sharks.
One of these animals named after Alfred Leeds was one of the largest teleosts and may have been preyed upon by Liopleurodon. A primitive one of these animals that lived in the Carboniferous period was Stethacanthus, and that period saw the extinction of armored ones called placoderms, such as Dunkleosteus. Some of these animals possess electroreceptors called Ampullae of Lorenzini or a (*) lateral line to sense movement.
