In Germany a disease got into some South American bears. They lost their luxurious fur, which would make you think they'd be as funny as a hairless dog. That's not the case this time, as apparently bears are somehow more terrifying when bald.
The fluorescent blue rings are beautiful, that's undeniable. Thing is, they appear when the octopus feels threatened. And when they bite, well, that's game over. The tetrodotoxin it injects you with hits you with paralysis, weakened muscles and lack of breathing before you die in minutes. Oh, and there's no anti-venom.
Off the coasts of Chile and Peru are the weirdest fake rocks you'll ever see. Basically, if you crack it open you'll think you're looking at the insides of a rock monster. What you're looking at is Pyura chilensis, a marine invertebrate that wraps itself in hard surfaces until it makes this gravelly appearance.
Some caterpillars blossom into lovely butterflies. You touch this oddly-spiked one and you're blossoming into excessive blood clotting and internal bleeding. Brushing against one isn't a death sentence, but a lot of times they hang out in bunches, so watch out.
This little escargot is slow but somehow eats fish. That's because its harpoon-like tooth pumps out a venom made from a combination of hundreds of different toxins. Once a fish is stabbed, it's paralyzed and then nibbled on by the snail, which is a fun way to die. That little tooth is also sharp enough to cut through wetsuits.
From the "oh god, keep this in the deep" files, the goblin shark is found very far into the ocean depths. Which is great, because not only does it look like a monster-movie extra, it also has a lovely spring-loaded mouth to eat its prey.
This one is odd, not so much in the mature version of the frog, but when it's a tadpole. When it's time to get out of the eggs and into the pond, they need to eat something. So here begins one of the grossest mother-child feedings ever concocted: Mommy Dearest lays unfertiilzed eggs and the tadpoles' fangs — that's right, fangs — cut through and eats them.
Fisheries in lakes hate these eel-like creatures, and with good reason. They latch onto fish like trout with their rows of tiny, razor-sharp teeth and suck them dry or tear at them until they're just bones. Millions are spent a year to eradicate them, and it can be tough to catch them altogether.
