I don't like snakes.  They are elongated, legless, carnivorous reptiles of the suborder serpentes.
They are scary especially the poisonous one.
Yes, and some retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca
Are there any countries that don't have snakes.
I think almost all do.  They are considered squamates.
I thought iceland, Hawaii, greenland and hawaiian islands, don't have snakes ?
Evolution of reptiles
Reptiles arose about 310–320 million years ago during the Carboniferous period. Reptiles, in the traditional sense of the term, are defined as animals that have scales or scutes, lay land-based hard-shelled eggs, and possess ectothermic metabolisms. So defined, the group is paraphyletic, excluding endothermic animals like birds and mammals that are descended from early reptiles. A definition in accordance with phylogenetic nomenclature, which rejects paraphyletic groups, includes birds while excluding mammals and their synapsid ancestors. So defined, Reptilia is
retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. Legless lizards resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamidae, and Pygopodidae).
Living snakes are found on every continent except Antarctica, and on most smaller
