: I always thought that the only poisonous lizards were the Gila Monster and Mexican Beaded Lizard both in the new world. The Komodo Dragon is also nasty but not poisonous. Im interested in learning more.
These lizards that you mention are not poisonous. They are venomous. There is a difference. A venomous creature can inject venom into its prey or an attacker. A poisonous lizard is dangerous if ingested.
