12. Glass Frog’s Transparent Skin

Natives of Central and South America, glass frogs exhibit an extraordinary translucent skin that reveals their internal organs. This transparency makes it easier for them to avoid predators by blending into leafy environments.

The smallest known mammal by mass, the Etruscan shrew possesses a rapid metabolism to fuel its non-stop energy. Despite its minuscule size, its fierce nature and voracious appetite make it a tiny giant.
