With a name like the Gila monster, this is one lizard you would expect to be fearsome, and in some respects you would be right. For one, the Gila monster is the largest land lizard in the United States and can reach lengths of up to two feet. It’s also one of only a handful of venomous lizards in the world.
Their fearsome size and venomous reputation has led to many Gila monsters being unnecessarily killed. This, combined with loss of habitat due to urban sprawl has led to the Gila monster becoming a species on the cusp of being endangered.
