The Northern Moon Snail hunts by encasing its prey in a mucus sheet before pulling it beneath the sediments of the ocean floor. Then, it drills a hole through the prey's hard shell by secreting acidic enzymes and using a modified radula. When the hole is drilled it can "sucks out" the soft inner body of the prey.
