They share a common characteristic - when in danger, both lizards and salamanders can shed their tails. This is where the similarities end.
Salamanders:
Because of their slowness and clumsiness, salamanders have evolved different defensive strategies than lizards. Their slippery flesh helps them escape the predator's grasp. They also use chemical defenses as they have glands that produce toxins. Most of the time, the attacked salamander positions itself with its back to the attacker, as most of the venom-producing glands are located in the tail area.
Lizards:
Lizards have evolved many different strategies that vary from species to species. For example, some can outrun an attacker, play dead, puff up their body to prevent the predator from swallowing, deliver a venomous bite, or even squirt blood from pouches located above their eyes to confuse their opponent.
