Snakes have no limbs and reptiles with long, barrel-shaped bodies, layered skin, no lids on eyes, and a forked tongue. Most snakes are not harmful, some are somewhat noxious, and others create a deadly toxic substance. The term venom is usually used to depict the toxin formed by a snake. All snakes are carnivores (meat-eaters) and heartless, which means the earth dictates their body temperature instead of being inside controlled. Thus, snakes are discovered mainly in tropical and mild areas and are truant in frosty atmosphere zones.
