In the animal kingdom, nothing is more important than being alive, and all living things have their own unique survival skills. Dogs eat bones, wolves eat meat, and that's what it is. However, some evil creatures specialize in eating ready-made things in other people's bodies, and even eat people's brains. These bacteria and parasites are zombies in the real world. Cherish life and stay away from them!
1. Zombie ants

A fungus that lived 48 million years ago was able to change and control an ant's behavior by releasing chemicals, turning it into a puppet of its own until the ant eventually died. The fungus still lives on Earth and usually parasitizes wood ants. Before returning to the canopy nest, wood ants are usually infected with this parasitic fungus when they pass through the forest floor cover, and their behavior is controlled by the fungus from then on. The fungus is constantly growing inside the ant and releases chemicals that influence the ant's behavior, making it a "zombie ant." Some "zombie ants" have since left their colonies and wandered out alone, looking for fresh leaves. The fungus-controlled "zombie ants" no longer have their own behavior and life, and the final stages of their lives are also the most painful and terrifying. In the last few hours of life, the "zombie ant" will crawl to the bottom of the leaf where it is located, and bite the central vein of the leaf with its jaw, trapping itself on the leaf, while the parasitic fungus is also locked on the leaf. When the "zombie ant" dies, the parasitic fungus sprouts from its head, produces spores and "launches" onto the forest cover at night, infecting other ants.
2. Zombie bees
When infected with a parasitic fly, bees become abnormal and resemble zombies. Adult female parasitic flies lay eggs in the bee's stomach, and the eggs become maggots in the bees, and after eating the bees' internal organs, the pupaes form. When bees collect pollen in the flower bush, they are extremely susceptible to attachment to parasitic fly eggs. When the parasitic fly eggs hatch, they will parasitize on the bees, living on the body of the bees, and when the parasitic flies continue to grow, they will invade the head of the bees and control the bees, and the bees will suddenly lose consciousness and will fly around, which is the so-called "zombie bees". Once the bees are parasitized by parasites, they will behave like zombies, and at night they will start flying around frantically until they are exhausted and die. We all know that the habit of bees is to come out during the day and hide in the honeycomb at night to rest, but the parasitic bees will appear so anyway that they will start flying around at night until they die. The parasites that parasitize the bees will transform from pupaes into parasites within 3 to 4 weeks after the bees die and begin to reproduce wildly.
3. Carnivorous zombie birds
This bird is called a giant, and you might think that this cargo being called a zombie bird is just a joke. But if you really think so, you're reading it wrong. Although this product usually loves to eat nuts and plant seeds, it also loves to eat birds and bats that are smaller than it, crush their brains, and then eat them beautifully.
4. Zombie caterpillar
A parasitic wasp called Glyptapantele employs the same cruel tactic, except that it implants larvae into caterpillars instead of cockroaches. However, in this case, the wasp larvae make the caterpillar their bodyguard. The larvae emerge from the caterpillar and stick to nearby plants, while the caterpillar stands guard for it on one side, attacking any object that tries to get close to them. Scientists who study this peculiar phenomenon have found that one or two larvae hide behind caterpillars. Wasp larvae may secrete some chemical to control the brain of the poor caterpillar, which is at best a walking dead, and the larvae have eaten only half of the caterpillar.
5. Zombie crab infected by crab slave insects
The female crab worm begins as a small free-floating mollusk in the sea, moving slowly and aimlessly until it encounters a crab. When this fateful day came, the female crab slave worm looked for a gap in the crab shell (usually in the crab claw), and then stabbed a "hollow dagger" into the crab's body, and she herself along the "dagger" injected herself into the crab's body, peeling off a layer of shell. After entering the crab's body, this slimy crab slave worm began to occupy the throne. She grows "root whiskers", which stretch out to various parts of the crab's body, wrap around the crab's eye handle, and penetrate into the crab's claws and feet. The female crab slave insect continues to suck the body fluids of the crab to grow until it finally bursts out of the crab's body. And starting from this protruding bulge, it will command this unfortunate good crab ship to spend the rest of the coexistence. A crab occupied by parasites will abandon its needs to serve its owner. It no longer molts, does not grow reproductive organs, or no longer attempts to reproduce. He won't even grow new appendages like other healthy crabs. Crab hosts no longer waste nutrients on themselves, but instead stagger forward in search of food for feeding their foster owners.
6. Fish whose tongue is replaced by zombies
Scientists have found a terrible parasite similar to an "alien creature" in the Mediterranean Sea that swallows the tongue of a snapper and replaces it, then lurks in the mouth of the host for further propagation. It is reported that in some waters, almost half of the fish are infected with this parasite. The "Betty" parasite swims into the gills of the juvenile fish and gradually swallows the tip of the fish's tongue, thus replacing this position, and obtaining nutrients by sucking the blood of the fish, and then growing and reproducing.
7. Zombie ladybugs
A wasp lays eggs in the belly of a ladybird and uses it as a host and food until the larvae grow. @oioi: So we can understand ladybugs for this wasp as the human body is for aliens. In some cases, the ladybug is not dead, but is only partially paralyzed. However, it is still used as an egg-laying nest by the cruel wasp, becoming a walking dead until it is eaten by the larvae.
8. Zombie spiders
Usually, spiders are natural enemies of other insects, such as the golden spider. But spiders also have predators. A wasp preys on Zodarian spiders and lays eggs inside the spiders. After the eggs hatch, the wasp larvae will slowly eat the parasitic spider, and then "bee occupy the spider nest" and slowly grow into an adult wasp in the spider's home. One of the wasp larvae also develops a cocoon before reaching adulthood. The females of these two types of wasps attack spiders during the day, using their long ovipositors to pierce the spider's nest.
9. Zombie snails
Snails are parasitized by a double-disced fluke called Leucochloridium paradoxum, a parasite that can enter the snail's digestive system and grow into a long tube filled with hundreds of reproductively capable tail crickets. Next, long pipes invade the snail's antennae, creating a strange, swollen, throbbing appearance to attract the attention of the birds. When birds eat this snail, they become hosts for the second stage of parasite growth. After the eggs are excreted into plants through bird droppings, they parasitize other snails and continue to begin their cycle of life.
10. Zombie cockroaches
The golden wasp enslaves the cockroach by pricking the precise position of the cockroach's brain and injecting a venom that controls the mind. This parasitic bee will turn the zombified cockroach into a private nursery. It lays an egg on the body of a completely relaxed host, and the larvae swallow the cockroach's organs and finally burrow out of the cockroach's body. Golden Wasp has only one companion in her life. Once the female is fertilized, she carries enough eggs to parasitize inside the cockroach, and each egg represents an unfortunate cockroach. Female golden wasps track a cockroach through their sense of smell and vision, and will perform lightning attacks, stabbing the cockroach's soft abdomen with their own abdominal needles. Cockroaches don't sit still and struggle desperately to resist. The golden wasp cuts off the mantis's tentacles and drinks its hemolymph, an insect that is rich in sugar and protein in its blood, allowing the golden wasp to replenish the energy lost in battle. When it finishes drinking, it bites the root of the cockroach tentacles and drags the zombified cockroach back to the nest like a puppy. The cockroach will never fall, it will walk normally and fully cooperate with its owner. This suggests that golden wasps can effectively eliminate the free will of the host through brain surgery. After about two days, the eggs hatch and the larvae bite a hole in the cockroach's abdomen and feed on the outflow of hemolysis. The larvae feed on the organs of cockroaches, but are smart enough to keep the nervous system for the last time. Because once the nervous system disappears, the cockroaches die. The golden wasp larvae cocoon inside the cockroach and become adult bees a month later and burrow out.
11. Head-For-The-Light Zombie Shrimp
Hook shrimp are not actually real shrimps, just shrimp crustaceans, this poor shrimp is the target of worms (echinococcus). After a hook shrimp is infected by a group of echinococcus, the echinosprud manipulates the hook shrimp's behavior to increase the chances of transfer to the next host. The eggs of Echinococcus are discharged along with the excrement of the host, and are ingested by hook shrimp. Therefore, in the body of the hook shrimp, the echinococcus will penetrate its intestinal wall and enter the body cavity to form a cyst, causing (depending on the type of parasite) positive phototropism or switching to land, so that the hook shrimp swim towards the water surface. Infected hook shrimp can change their response to olfactory and mechanical stimuli and can bend themselves to extremes. When you see a fragment, you can also wrap it up. All of these changes increase the chances of being preyed upon by the parasite's new host.
Zombie Rat/Cat Poop Love Triangle
Of all the zombies, the Gangdi Hookworm is the most terrifying because it can be transmitted to humans! This product can be copied continuously in cat, and when the mouse eats the cat (the mouse really loves to eat cat shit), the bug burrows into the mouse's brain and destroys it. Toxoplasma can make the mouse forget its dislike of the cat, and even be attracted to the cat, and then the cat will easily eat the mouse. Scientists have also found that the toxoplasma can also be transmitted to humans, affecting the human mind, such as making it easier to think of cats and mice. Stay away from the cat's poop!
