Great defenders

Many salamanders have built-in defense mechanisms, another factor contributing to their survival over the millenia. Their skin secretes a slimy coating, making them difficult to capture. Some toxic salamanders warn predators with bright coloring. Others, such as the Southern red salamander (pictured), simply benefit from looking like a more toxic species.
