7 Adorable Animals That Spawn Terrifying Babies

This literal headdress assists the caterpillar with passive camouflage, but in a pinch it uses them defensively as well. Whenever the three-spot caterpillar feels threatened, it'll start violently thrashing around, causing the heads to rattle and bounce intimidatingly. It's even thought that the heads can be used to bludgeon an assailant into submission should it get close enough. You don't know PTSD until a living shit whips you with a flail made out of decapitated heads.

All shark eggs are pretty weird, but elephant sharks produce something that looks like the crap H.R. Giger would take after a heroin balloon popped in his intestines.

These fish (despite the name, they're actually not sharks) can be found just east of Australia, the world's most ridiculously evil continent. Come breeding season, the females lay their freakish egg capsules, which can take up to eight months to hatch, and leave them in waters just shallow enough for unsuspecting tourists (that's you!) to squish between their toes.

Everyone knows pandas are cute and cuddly -- they're like giant stuffed animals. Even if you objectively know that they're immensely powerful bears that could dismember you in a heartbeat, there's something about that patchy face that says he wouldn't mean it, or at least would feel bad afterward. What most people fail to realize is that delightful pandas don't start out that way. They're not the fluffy, black-and-white ball of adorableness you've seen in cute gifs and conservation posters. They're more like somebody spliced creepy little baby arms into those worms from Dune.

Those subterranean mole-wights are, of course, pandas fresh from the womb. The ones above have had some time to at least grow a little fur to distract you from those faces of eyeless soul-hunger. Go back even earlier, and they look like this:

What the hell? Do pandas not come with eyes? How do they get them? Do they ... oh God, do they steal them?

Just when you thought you'd seen everything, the Venom symbiote shows up in your garden and turns your tomato patch into something out of a Riddick film.

Incredibly, this monstrosity is the caterpillar version of the gentle owl moth, and while they might not be under the thrall of a murderous alien parasite, the origin story does have something of the supervillain to it: It was discovered on the edges of a volcanic crater on Italy's Mount Vulture.

Those corkscrewing terror-stalks popping out of its head, also called "modified tubercles," aren't just for show. When perturbed, owl moth caterpillars rear up and wave them around menacingly like Cthulhu's face-tentacles. That should be more than enough to put most birds, which already have an accelerated heart rate, into full cardiac arrest. And if not, well, it can always call in its cousin ...

We didn't have to go far to find that misshapen, malformed homunculus up there. That's a tadpole of the species Rana temporaria, or the common frog. During one stage of their development they sport external gills, which explains those strange, diseased-looking growths you see poking out from the sides.

Their mouths aren't fully formed yet, leaving them with a kind of pouty sucker on their face that looks like something between a perpetually staring Cyclops eye and an unwashed Fleshlight.

Check them out all in a row: It looks like your bag of potatoes gained sentience and started organizing against you.

It's like somebody turned a Pokemon inside out. You ever give a small chew toy to a big dog? This is what you pick up from the lawn the next morning.

Scientists love these little guys because, in addition to being genetically pliable and easy to care for, zebrafish have Wolverine-level regenerative abilities that allow them to regrow their fins, tails, hearts, and even brains. Yes, the zebrafish knows your first impulse upon seeing it is murder -- hot, steamy murder for the thing that should not be -- and it's cool with that. It's evolved to counter that response. Go ahead. Do your worst. It pretty much cannot die. Although it clearly wants to.

It is far too ugly for the reaper.

The kea is a fairly exotic mountain-dwelling parrot from New Zealand, best known for the bright coloring on its wings and its propensity for intelligence (the kea can even solve simple puzzles). And since it's so goddamn smart, the first question we'd like to ask it is: What's the deal with your terrible babies?

Jesus! It looks like it wants to puke just thinking about itself. Yes, the beautiful multicolored genius parrot started life as this abomination, which looks more like something your cat coughed up than a living thing. Much like Neville Longbottom, puberty is apparently very, very kind to the kea.

According to experts, the reason the kea is listed as a "vulnerable" species is "mainly due to mammals which are able to get into its nests to steal eggs and young." This implies that kea mothers are just as repulsed by these things as we are, leaving their nests unprotected while they head off to the local parrot bar to get plastered and forget about their ungodly spawn for an hour or two.
