1. Gila Monster - Slow and Cunning

These lizards are famous for having a tail that looks a lot their heads, making it harder for predators to know which side to attack. It is also one of few lizard species that is poisonous. The Gila monster’s unique look allows them to walk about without a constant need to search for hiding places, leaving it with more time to spend eating and sleeping.
2. Koala - Eat Less, Sleep More

It may surprise you to learn that koalas are not part of the bear family, but rather they are marsupials that spend most of their time at the tops of trees. These animals can sleep for 18 hours a day thanks to their amazing ability to get all the water they need from the eucalyptus leaves they eat. The koalas’ drinking habits are said to be the source of their names, whereby in the local indigenous language, 'koala' meant “no drink”.
