Each crocodile jaw carries 24 sharp teeth meant to grasp and crush, not to chew. That’s why they swallow stones that grind the food inside their stomachs (the stomach stones also serve as ballast). The teeth are continuously replaced along the crocodile’s life. Crocodiles can exert enormous pressure when closing their jaws, but the force for opening them is so weak, that an adhesive band is enough to keep a large crocodiles’ jaw shut up. The powerful jaws can be extremely delicate, working like pencils, when removing offspring from the nest. Still, beware at the tail: it inflicts powerful blows.
