1. Cat nest parasites

Cat nest parasite is often said toxoplasma gondii, this bug can control the human brain, make people more likely to think of mice and cats, serious can affect human feelings and behavior, and even lead to schizophrenia, and if infected with pregnant women, it will cause serious damage to the fetal brain, so pregnant women must stay away from cat beds, cat litter boxes and other things.
This parasite mainly infects cats and mice. Larval eggs will be excreted with cat feces, and mice like to eat cat feces (this is true), Toxoplasma gondii will enter the mouse body to develop, and so on to a certain extent, Toxoplasma gondii will control the parasitic mouse to attract the attention of the cat, making the mouse easily eaten by the cat, the cycle repeats, but researchers still do not know the mechanism by which this parasite changes human behavior.
2. Golden Wasp
The golden wasp is a parasite that specializes in infecting cockroaches, which lose all will when infected with golden wasps. The golden wasp will drive the cockroach into its underground nest and lay eggs on the cockroach abdomen, and the hatched young bees feed on the cockroach's body, and the terrible thing is that the cockroach is still alive at this time.
3. Carnivorous zombie birds
This beautiful bird looks very harmless, but this is a real zombie bird, it has a terrifying hobby, loves to eat brains. It will prey on birds and bats smaller than it, crushing their brains and eating them.
4. Zombie snails
The double-disced fluke, called Leucochloridium paradoxum, parasitizes snails, altering the snail's digestive ducts and forming long tubes filled with reproductive tail crickets. When the cymbal worm matures, it will invade the snail's antennae with long tubes, making the snail colorful and eye-catching, which will attract the attention of birds. The birds eat the snail, and the eggs are excreted into the plant through bird droppings, infecting the new snails.
5. Zombie Locust
Crickets and locusts are infected by a parasite called Spinochordodes tellinii, which forms larvae in water, and once the crickets and locusts grow, they control the locusts to drown in the water, and the golden nematode returns to the water to lay eggs and start a new cycle of life.
6. Zombie hook shrimp
Worms that live in water (echinococcus) attack hook shrimp and parasitize them. Echinococcus's manipulation of the hook shrimp manipulates the hook shrimp's behavior to increase the chances of transfer to the next host. In addition, hook shrimp may also ingest the eggs of echinococcus, which will penetrate the intestinal wall and enter the body cavity to form a cyst. They control the hook shrimp's body and change the hook shrimp's response to olfactory and mechanical stimuli.
7. Zombie bees
Bees are infected by a parasitic fly, which becomes like a zombie and prefers to lie out day and night. Parasitic flies lay eggs in the bees' bellies, and these larvae eat the offal of the dried bees and form pupaes inside the bees. Bees are susceptible to infection when collecting pollen.
8. Zombie caterpillar
A parasitic wasp called Glyptapantele implants larvae into the caterpillar's body, the larvae release hormones to make the caterpillar their bodyguard, the larvae leave the caterpillar to stick to nearby plants, and the caterpillar protects the larvae, of course, while protecting the caterpillar is also the best food for the larvae.
