The truth about animals that you don't want to know (21 photos)

Have you ever wondered what really happens in the animal kingdom? Here are some of the craziest animal facts that may be hard to believe, but they're true.





1. There are lizards that can literally squirt blood from their eyeballs.



2. Female butterflies have teeth in their reproductive system.





3. Cordyceps mushroom grows inside the body of an insect, infects the brain and causes it to kill itself (in a broad sense). Luckily it only works on insects



4. Dolphins are smart enough to commit suicide



5. Male dolphins kill the babies of female dolphins to force them to breed again. Females have found the perfect way to counter this



They mate with every male they encounter until they give birth. So all these males could say, “Damn, maybe that's my baby,” and protect the female and her baby from danger.

6. You are more likely to be killed by a cow than by a shark (the chances of this happening are much higher)



7. A kangaroo will drown you to hell if given the chance.



8. Female ferrets die if they don't mate during heat.



9. Male giraffes slam the female's head against her bladder until she urinates, then taste the urine to determine if the female is ovulating.



10. Horses don't have a gag reflex.



11. The honeybees you see in your yard live the last 2-3 weeks of their lives.



12. Cat mating is essentially BDSM. The male's penis has backward-curved barbs that cause pain to the female when the penis is pulled out (the pain causes ovulation). In turn, the cat then beats the cat with its paws



13. When a lion takes over a pride, he kills the offspring in the pride to get rid of future rivals and send all the lionesses into heat



14. The lobster's brain is in its throat.



15. Hyenas give birth through their penises (yes, female spotted hyenas have penises) and most babies don't survive.



16. Pigs will eat the entire human body, including bones. Convenient to dispose of the body. Beware of pig farmers



17. Pelicans have a habit of passing through flocks of other birds, picking up chicks and eating them alive.



18. Sand tiger sharks eat each other in the womb. A mother shark has at least a hundred eggs, and once they "hatch" inside her, they will eat each other, and usually only one or two come out of the womb



19. Tasmanian devils live in burrows. The male breaks into the female's hole and attacks her. He will hold her hostage for days, biting and scratching her, not allowing her to leave, until she exhausts herself and allows him to mate with her.



20. Out of pure sexual frustration, male sea otters rape baby seals if there are no female otters nearby.
