The habitat of snakes varies from species to species, with a wide variety of habitats, some living in caves and holes, some on the ground, some in trees, and some in water.

Snakes are thermophiles whose body temperature varies according to air temperature, because snakes themselves do not have a well-developed thermoregulatory mechanism to produce and maintain a constant body temperature. Snake belongs to the thermotropic animals, the degree of evolution is low, its distribution and survival by the climate has a greater impact on the stability of a more fragile biological groups.
