"Oh Deer, You're Grizzly": When Great Tits Are Deadly (Even Sadistic) & Hairy Balls a Mystery (Even Mystical)… Man, "our world is downright weird."

I was watching the B.B.C. documentary series Weird Wonders of the World and Nature's Weirdest Events on Netflix when I was told about some pretty gruesome tits that hack into into the skulls of still-writhing, still-living bats in agony and eat their brains.

Don't be fooled: These birds are (per the Scientific American®) — Don't be fooled: These birds are (per the *Scientific American*®) "*murderous, rapacious, flesh-rending predators!*"

Apparently, "herbivorous" deer also have been documented to eat meat! The episode showed deer eating a live chick (and I found an article with YouTube™ video footage used), though the National Geographic article I found also shows them eating human corpses, too. Grizzly!

Apparently, these are balls of Aegagropila linnaei algae, also known by its Japanese name 毬藻 ("マリモ"; "marimo" ⇐ 毬 "マリ"/"mari" 「ball」+ 藻 "mo"「algae」).

Have you seen any good informative programs recently that just made you think "Wait, wait, wait… WHAT‽ What the heck‽ That can't be right!" Or have you learned something today (or "recently") that made your head and double-check just to be sure?
