Biological Curiosities:

- Rattlesnakes rattle is formed by the accumulation of the outer part of the epidermis, which accumulates in the final part of the tail. By the amount of buttons present in the rattle of the animal it is possible to know how many changes of skin he has passed.

- The gecko and some species of lizards and iguanas have an important resource to escape their predators. These scaly animals, at the predator's attack, release the tail part (which is moving for some time), thus attracting the predator's attention. Meanwhile, the prey manages to escape. Over time, the lost tail part regenerates.

"The only lacertile reptile belonging to the order Squamata, venomous (possessor of poison) is the gila monster."

About three meters long, the Komodo dragon is the largest scaled reptile.
