Some reptiles have evolved tough, protective shells to defend themselves from predators. Tortoises have thick, bony shells that can withstand extreme force, while snapping turtles use their powerful jaws for defense. Armored reptiles like crocodiles and alligator snapping turtles rely on both shells and strength.
These reptiles have survived for millions of years, using their defenses to outlast predators and environmental changes. Their unique adaptations make them some of the most resilient creatures in the animal kingdom.
