These little monsters are one of only two poisonous lizards in the world. They kill their prey with the venomous saliva they produce while chewing. They live in the Southwest of the US and in Mexico and are the only venomous lizards native to the U.S. They are heavy and slow-moving and may reach a length of 2 feet.
They live in brush areas, lush deserts, and oak woodland, and find shelter in locations where moisture is within reach. It used to be believed that the Gila monster had toxic breath and that its bite was deadly, however, it is known now that it isn’t fatal to healthy adults.
The duck-billed platypus has deadly venom, which makes it one of only a few mammals on earth of that kind.

While the venom isn’t deadly for humans, the agonizing pain paralyzes its victims. Despite posing a danger to humans and animals alike, it is an iconic symbol of Australia and has appeared as a mascot at several events, as well as been featured on the Australian twenty-cent coin.
