There's also another parasite that attatches to a spider and hijacks its brain so it spins a web fit for a wasp nest while the parasites steals the nutrients from the spider and when it's done spinning the web the parasite kills it and releases wasps to continue the cycle Edit: its called the "ZATYPOTA PERCONTATORIA"

[@DrJ-hx7wv]

And evolution cannot explain any of them

[@QuesoCookies]

@@DrJ-hx7wv Of course it can. Parasites that happened to invade the nervous systems of certain organisms caused those organisms to behave in unusual ways. Whichever ways happened to be beneficial to the parasites naturally caused them to survive to reproduce and have young that invaded in similar ways. And what was random induced behavior gets less and less random with each generation of survivors until the induced behavior no longer appears random. Simple.

Parasites do actually give back to the host sometimes, like with some orchids that take nutrients from nearby fungi, then give them back later.

[@user-uj6tc4pj1x]

That sounds neat. "Parasite" is a kind of symbiotic relationship. The other types are mutualist (help each other), and commensal (one benefits without hurting the other). Assuming the orchids hurt more than they help, maybe they're still parasites. But what you describe sounds a lot like mycorrhiza, which are usually described as trade relationships that many plants and fungi use, but may not be fair (likely varying with each sugar-for-nutrient trade).

[@occultninja4]

Allow me to gross you all out. Close your eyes and imagine. You're a guy wandering through the woods, hunting a fox to make a hat out of it's fur, but little did you know, a most insidious creature has latched onto your clothes and crawled into your pants. Much like a tick or a mosquito, the stealthy creature works it's way over your skin, maneuvering it's way towards it's desired target area. A most... Unsavory of target areas... You can use your imagination to inform you of where our opportunistic creature is heading. With the careful precision of a brain surgeon, it latches itself onto the base of his reproductive organ, delivering a painless bite he had no way of detecting, and initiating a horrifying process that will leave him forever changed. Days pass and our man has not experienced any side effects as of yet, aside from a strange... Euphoric feeling, and occasional mood swings. However, inside of his body, very disturbing things are happening. The insect that bit him is not interested in simply siphoning see blood and leaving. No, it is there for a much longer haul than that... Tendrils from inside of it's mouth penetrate into him, invading and infiltrating him, connecting it's nerves with his own, and delivering him with an inexplicable sexual euphoria that grows stronger as the days pass. The strange persistent and addicting good feeling he's doused in leaves him complacent, forcing his guard down. It works much like the irrisitible and numbeing power of opium, slowly but surely addicting him, coaxing him onto complacency, making Jim withdraw from his world, no longer caring about even his daily obligations and instead choosing to spend his time blissfully frolicking in the euphoric ecstacy of his own solitude. Thus, it's no surprise that, by the time he discovered the creature latched onto him, his capacity to care had been withered away. Deep down he knew it was abnormal and he should do something about it, but the crippling drugging the creature was giving him was keeping him from taking action. 'Ill handle it later', 'it can wait', 'jist a little longer', 'I'll handle it tomorrow...' Those were the thoughts that came over him, a constant neverendong cycle of procrastination that kept him powerless to do anything about the creature latched onto him, which allowed it to move along to it's next phase... Day by day, his testicles shriveled and dried, hardening and drying out, as if being sucked dry and devoured inside out. All sensation from them was all but gone. The only thing he felt from the area was that constant euphoric bliss that seemed to continuously radiate from it. There was not even any notice when the dried husk of his male reproductive factory broke off and fell away from him, leaving him permanently sterile, as the creature continued it's horrible sins against humanity's genetic lineage. Every night, he was plagued by strange.. Dreams.. nightmares, of a female demoness, pleasuring him, making love to him, seducing him, and sucking the very life out of him. A vampire, draining the life out of him slowly but surely. Each night she brought with her a new world of pleasure, and each morning, she took.woth her a bit of his soul, leaving him less and less and less human as the days progressed, and his situation got worse and worse... A week has gone by, and signs of he affliction are now visible... His muscles mass has began to decrease, perhaps a symptom of his infection, or perhaps something else. His more masculine features were replaced with more frail and... Weak ones. The trait left of his prominent male features was a growing protruding beer gut that's become more pronounced as of late, something he cherishes and takes much pride in, in a manner that seemed much too... Intimate than to be simply pride over a masculine attribute... However, nature is a horrible mistress, and what was happening to him was not simply a Misplaced obsession with his belly. No... The creature that had latched itself onto him was... Well... Impregnating him. Thousands, possibly hundreds of thousands of wriggling undulating worms resided within his belly, feasting on the partially digested food traveling through his tract, growing, maturing, and eventually, being 'born' onto this world through his feces, to start their heinous disgusting life cycle all over again. Our Hunter never quite recovered from his... Affliction. It was too much to hope for. Humans are cripplingly vulnerable to dopamine and chemicals that can replicate it's effects, something this hellish creature took full sadistic advantage of. There it remained until the day it's host died, it's tail burrowed inside the fleshy hole left from when his dried dead testicles fell away, injecting it's vile brood inside the orifice to impregnate it's new 'wife', flooding his mind with otherworldly ecstacy all the while to trap him in a hell too cruel for even those who commit the sin of lust... -I may have gotten a bit too into that. Bear with me I'm getting into writing horror and had to give it a try xD-

[@rusticpath2244]

Wanna know a fun fact? Every single human being on earth has had a parasitic infection at least once in their life. Even you. The most interesting one for me comes from pigs. They lay their eggs in the skin of the host and when eaten it will then infect their next host and lay even more eggs in their new hosts skin. So if you're having pork, be sure to cook it thoroughly.

this is very late but perhaps because it is not a true parasite but instead a parasitoid- a parasite that deliberately kills its host, while many true parasites try to keep their hosts alive.

I would grab the worms with the tweezer one at a time and the minnow would turn it's head really fast but wasn't swimming away. I did this till all 3 were out. sadly the minnow died a few days later.

I saw number 2 on an episode of The Most Xtreme on animal planet way back in the day. For my elementary school state writing test, I decided I wanted to write about it. Only one big problem- I forgot what the darn thing was called. So I made up an entirely incorrect but believable enough name so I could finish it. All of my facts and information were spot on and accurate! If only I remembered the name. Still scored well on it. This was back in the day where computers and internet access were incredibly limited for me and the show was cancelled and stopped airing at some point so there was no hope of ever seeing it again. But in the episode it placed number 1 as the most extreme parasite I think? Sorry for the word vomit comment I just was really excited to have this fever dream of a parasite actually be real and learn its actual name isn't burroclaudia lmao

[@jamesdiponio9242]

Also something to note: parasitic behavior is a natural thing, just like someone else here mentioned an growing baby in the womb takes nutrients from the mother until ready to be punched out. By that description every single mammal does have some type of natural paracidic actions in the start of their lifetime.

[@josephburchanowski4636]

I really get tired of people comparing offspring to parasites. If you have a population of creatures, and you remove all the parasites from them, the population of creatures doesn't suffer. If you remove all the offspring from a population of creatures; that population will die out. Heck the crabs in the video help highlight that the two aren't the same. Both the eggs and the barnacle require parental care, but there is a reason one is considered a parasite and not the other. The eggs are the next generation, carrying the genes of the host crab and continuing the species. The barnacles completely removes the hosts ability to procreate, and creates a new generation that will disable more crabs. If the barnacles were to infect all the crabs; they would cause the extinction of them both.
