A worm-hunting cone snail species feeds on fireworms, and is unaffected by the prey's sharp bristles.
A species of fish-hunting cone snail quickly immobilizes its prey and swallows it.
A snail-hunting species of cone snail stings its prey repeatedly, inducing the prey to thrash about.
Unlike a hook-and-line type fish-hunter, a net-hunting cone snail lures its prey into its wide mouth.
