The Lyrebird Mirror of Sound
A beautiful bird with an amazing singing voice, a voice so expressive that it can mimic many sounds, be they natural or artificial. Some recorded examples include chainsaws, camera shutters, and a car alarm. They can also mimic humans, though this is less common.
Members of this family of fish have electric eye muscles, attacking prey with quick shocks. Pair this with poisonous spines and the ability to hide in sand and this fish becomes pretty vicious.
The Healing Power of Sloths
Sloths aren't exactly known for their cleanliness, but the upside to this is that they house loads of bacteria that help the animal heal from wounds much faster than others. Some research suggests that sloth hair may even hold a secret to combating cancer.
Opossums eat venomous snakes without suffering ill side effects. That's because opossum blood contains a protein that specifically seeks out and neutralizes toxins. This includes toxins the animal wouldn't normally encounter in its usual habitat, like those found in snakes from other continents.
The Never-Ending Axolotl
This amphibian has regeneration abilities, but not the usual tail or limb regeneration. This little guy can recover any body apart or organ, including its brain, heart, or entire head. But that's not all: it's also able to adopt the discarded pieces of other axolotl, effectively stitching itself back together.
