The sawfish uses its long, toothed rostrum not for killing, but for immobilizing. Also known as the carpenter shark, its nose is covered in electrosensitive pores that detect small movements in the water. When it detects food nearby, the shark slashes its nose through the water to stun prey long enough to gobble it up.

The rostrum is a lot more maneuverable than I thought. Look at it juggle that fish into its mouth.
