Poisonous lizards are exceptionally rare. Basically the Gila monster is the only lizard with true venom. Komodo dragons are often considered poisonous but its not quite true.

Vividly colored critters are often poisonous but are just as often using vivid color to mimic poisonous ones.

The Komodo dragons bite is so rife with infectious bacteria that you might wish it was something as trivial as a venom!

Limbs bitten by a Komodo dragon often must be amputated, even if modern medical treatment is initiated immediately.
