11 Creepy Facts About Cute Animals That'll Make You Say "Why Did You Ruin This For Me?"

It's like a form of self-culling, it reduces competition and food shortages – individual larvae are more likely to survive when they have fewer siblings to compete with.

These "love darts" are pointy calcium structures that remain attached to the shooter and bind the two slimey lovers together. As you might expect, shooting pointy things as foreplay can be dangerous, and these love darts often pierce the internal organs of fornicating snails.

Male otters are known to mount baby seals. Because otter copulation involves the male holding the female's head under water, this act often also results in the drowning of the baby seal (and sometimes that of the female otter, too). Sometimes, the male otters are known to continue mounting the body of the dead seal for up to a week after its death.

They can also pass the infection onto humans through their urine.

Well, not poo exactly, but a slightly less digested waste – fecal pap. Right from her cloaca.

There have been multiple, gruesome stories involving pigs eating human flesh. They don't lust after human flesh or anything, they will just eat almost anything.

Deers have been known to eat all sorts of animals – including birds, rabbits, and even human remains, as pictured above. The reason they do this is likely because they're lacking in certain nutrients such as phosphorus and salt. They're not really the harmless herbivorous we perceive them to be, but opportunistic omnivores.

Few animals carry leprosy as it is a pathogen that can only survive at a very specific temperature – i.e. human body temperature. Armadillo body temperature is remarkably close to that, which is unfortunate for them, because that's how humans actually passed the disease onto them some 400 years ago. They're returning the favour.

They digest food so quickly that not all nutrients are absorbed, and some of their waste still contains nutrients. So rabbits start their mornings with a nice helping of soft and nutritious feces, directly consumed from the anus. Frankly, it's pretty clever – they're just recycling their food.
