The Mexican Beaded Lizard and it's relative, the Gila Monster are the only two venomous lizards.
The venom glands are in the lower jaw and the venom is channelled into grooves in the teeth. The bite although painful is rarely fatal to humans. Numbers are decreasing annually mainly due to agricultural activity i.e. burning and cutting of bushland.
