venomous snake

A venomous snake is a snake that uses modified saliva, venom, delivered through fangs in its mouth, to immobilize or kill its prey. (In contrast, most non-venomous species are constrictors which suffocate their prey.) Venomous snakes include several families of snakes and is not a formal classification group used in taxonomy.
