1. Lumholtz' tree kangaroo (Dendrolagus Lumoltzi)
Adorable though they may be, these marsupials have been known to add a dash of protein to their predominantly herbivorous diets by horking down the occasional bird brain. Unconcerned with waste management, tree kangaroos generally discard the rest of the corpse after consuming the gray matter.

2. Great tit (Parus Major)
The great tit's powerful beak is an excellent nut-smashing tool. It also doubles as a handy-dandy bat-skull-crusher. Seeds and insects are the favored cuisine...
MoreIf you like geology, you’re used to relying on an active imagination. Most geologic processes occur too slowly to see them play out for yourself. Many of the exceptions are dangerous enough that you might not want a front row seat or are rare enough that the odds of being there to witness them are disheartening. Sometimes, though, the Earth throws us a bone—or in this case, a gigantic slab of granite.
One interesting way that rocks weather and crumble apart is called “exfoliation.” Like the skin-scrubbing technique, this involves the outermost layers of exposed igneous or metamorphic bedrock sloughing off in a sheet. Over time, this tends to smooth and round the outcrop—Yosemite’s Half Dome providing a spectacular example.
We’re not entirely sure just what drives the peeling of an outcrop’s skin like this, but the classic explanation is that it’s the result of bringing rocks that formed at great pressure up to the surface. Once there, the outer layers can expand slightly, creating a physical mismatch with the layers below them.
