How did snakes develop venom as a way of killing when no other reptiles did (and so few animals have)? How did the variations in kinds of venoms come about? Did constricting snakes lose their venom?
In: Biology
There are a few types of venomous reptiles that are not snakes. Wiki includes: Gila monster and its kin the Mexican Bearded lizards and the Komodo Dragon and some of its kin. (They used to think that was all bacteria, but found that was incorrect.)
