When most people think of an animal, they probably imagine something cute and fluffy. But whether you realize it or not, there are also a lot of scary and disgusting animals in the world. Of course, these animals are still living creatures that should be respected, but you might want to keep your distance from them, especially after hearing these disgusting animal facts. 

Every animal is unique, but there might be such a thing as too unique. The following disgusting facts about animals cover everything from vomit to feces to sex organs. These actions sure aren't pretty, but they're oddly fascinating. Of course, they might make your stomach churn just hearing about them, so this information is not for the faint of heart. So, which bizarre animals have habits that will make your skin crawl?

  • Flies aren't some obscure animal like many other disgusting creatures. No matter where you go, you're sure to see more than enough flies. Of course, they're annoying little insects that just won't leave your food alone, but they're even grosser than one might think.

    If you've heard the rumors about flies vomiting a lot, then yes, it's true. Flies are not made to eat solid human foods, so they need to liquefy the food to make it digestible. To do this, they use their mouthpiece to turn the food into a liquid, and then they regurgitate it so they can easily eat it up. 

    On top of that disgusting process, flies also poop a lot. Since flies vomit so much, they need to drink lots and lots of water to avoid dehydration. What goes in must always come out, so most of the time, flies poop and vomit whenever they land on things. 

    It's also important to note that flies taste with their feet. And they taste a lot of things, even objects that aren't food, including dog poop. So, when a fly lands on your food, you never know what kind of cringe-worthy germs they might be passing to you.

    Tongue-Eating Isopod Females Eat The Fish They Infest From The Inside Out

    Cymothoa exigua is a crustacean and parasite that lives in the ocean, but many refer to it as the "tongue-eating isopod" due to a disgusting habit that it has. As adults, these little critters can turn from male to female, which is part of how their tongue-eating behaviors occur.

    As juveniles, these isopods infest a fish by entering through the gills. At first, they are all males, but then one will turn into a female. The single female then attaches herself to the fish's tongue and sucks the blood from it. Eventually, she causes the tongue to shrivel up. 

    But fish can survive with no tongue, so as the fish lives on, it uses the parasite like a replacement tongue. The female continues to feed on the fish's blood and mucus while the males usually stay in the gills. The female might even mate and reproduce with one of the males while hanging out in the fish's mouth. 

    Thankfully, these disgusting creatures only infest fish, not humans. But you could find them in some of the fish you eat. So, if you ever catch a fish to cook, it might be a good idea to check out its mouth first.

    Movies and TV shows like to make silly scenes where kids get covered in leeches after wading through some water. Yet, those events can be very real and aren't at all amusing in real life. Leeches are soft, blood-sucking parasites that are exceptionally great at squeezing into small spaces. So, you don't want to mess with them.

    But one man has witnessed leeches larger than you could ever imagine. Mark Siddall of the American Museum of Natural History has closely researched leeches, and he doesn't seem to be afraid of putting them on his arm for photos.

    While the size of a leech can greatly vary, Siddall discovered that the great Amazonian leech can grow up to 18 inches long, which is about a foot and a half. For reference, that would be about the length of the average man's forearm! Leeches can survive even after losing 80% of their body's water, so these massive leeches are a force to be reckoned with.

    Suriname Toad Babies Erupt Out Of Their Mother’s Backs

    Most animals give birth by laying eggs or through a live birth like humans. But the Suriname toad prefers to be unique. This flat, leaf-like amphibian births her babies from her back rather than the usual reproductive organs. And yes, it's just as unsettling as it sounds.

    In South American rainforests, these toads mate when the male places dozens of fertilized eggs onto the female's back. Her skin begins to slowly grow around the eggs, and her back soon looks like inverted bubble wrap. Each indent is a small womb for a baby toad. 

    Once the babies have grown enough, instead of hatching normally, they erupt from their mother's back as tiny froglets. They remain in the water as they continue to grow. But unlike most frogs and toads, they skip the tadpole stage completely.
