    "Horrifying, but wait, it gets worse." - Parasites in a nutshell.
  • I had no idea the corpse flower was a parasite. I never knew entirely what it was, but I thought it was just some weird plant
  • @jimmutenken3989
    I always thought Rafflesia flowers had something interesting about them, but I never knew they’d have such a hardcore strategy for survival.
  • @redozmasoma
    The No. 1 isopods are so polite "Oh, someone is already at the tongue, ok let me just chill on the gills" lol
  • If scientists manage somehow to fuse a couple of these together in a lab, we would have a zombie apocalypse.
  • @HeavyMettaloid
    Now the "Oh, barnacles!" swear from Spongebob makes sense!
  • @cyirvine6300
    I had a lizard that had eyes that would bulge out and pulse like that. Now I freak out wondering if it was infected. Great video with content!
  • 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"
  • @NatureWitch
    Poor crabs everything and everyone wants to eat them or use them.
  • @Vannah272
    "It invades the eye stalks of snails, turning each eye into a pulsating brood sac that looks like a juicy caterpillar ready to be snapped up by the parasite's next host." My eardrums will never be clean again.
  • I always hope these animals (and even insects) don't suffer. I can't imagine how painful these things could be... or other forms of suffering, like not being able to breathe.
  • Those parasites in the snail's 'eyes' are def one of the most horrific creatures. I'm glad these small creatures cannot 'think' the way we do. Nature is so damn macabre sometimes!
  • @wolfonthezoon
    As a wise man has once said " Damn nature you scary"
  • @X-SPONGED
    2:53 "Instead, they seem to have trouble breathing" Wait, So these bugs give fish eternal asthma ? Oof, that's rough, buddy. I feel ya...
