      4. Mateusz Czerniawski

        @SciShow 2 questions: 8:40 how this is possible? How that even could evolve? Is the mitochondria a parasite? Could be some parasite story background in primiry cells and mitochondrias fusion?

      5. TheDerpyfredbear

        Baby's are basically a parasite Lives of a human Kick it out it will get hit by a car

    2. Boxed In Gaming

      i actually dind't know the corpse flower was a parasite. even though i live in indonesia

    3. WinterFrost_Productions

      "To feed on the fish's nutritious FlUiDs" Ew.

    4. The Clumsy Kitten

      I wish parasites did not exist

      I got rid of a "big parasite", still sucking anything and everything out of the life of my kids and I. That leech needs to get "treatment" , like years ago. I have no idea why that has not happened already. PERMANENTLY.

    7. ThatAspieCalledMyth

      a bit surprised and disappointed he didn't mention cordyceps, the zombie ant fungus

    8. Hobostarr180

      I remember NatGeo did a video over the snail eye worm things years ago. Horrified the crap out of me as a kid

    9. Line-Marie FORTIER

      Intresting, but BEUEUEURRRKKKK. I stopped before the snail!!!

    10. Kenneth Mcghee

      I think that crab barnacle got to sum these guys on the earth

    11. 必きり

      I can only hear the Crash Course Chemistry intro song when he speaks...

    12. Vicarious Gamer

      Humans being in at least the top 5 of all parasitic life. There ya go, a show topic for you. You're welcome :)

    13. Tash YzD

      The Question Is ; .Why Must PARASITES Exist

    14. Nathan L

      When I saw the snail, I wanted to take holy water eye drops

    15. Megan Barnett

      #1. Me :(

    16. Andre Bowman

      We are all paracites sucking down on the earth's recources and gives iy nothimg in return

    17. The sinner Jim Whitney

      There's a particular wetland near my home in West Virginia in which I've found what I feel is an inordinate amount of frogs and salamanders with additional or malformed legs, I always assumed it was due to pollution due to quite a few industrial facilities (powerhouses, steel mills, chemical plants, and natural gas compressor and metering stations) and the coal mining runoff in years past. I'm sure that has some effect, but I'd be very interested to learn whether there's a lot of that family of worms in the water. Interestingly, it's a natural wetland, but only sorta. It's along the Ohio river, and if left to nature would probably be under the river's surface almost all year, but since we built many locks and dams along the river to make it year-round navigable the river channel has become narrower and deeper, exposing the wetland to year-round air. Side note, how the hell does a creepy parasite video from smart folks like the SciShow crew not mention the mind-control cordyceps fungi?! Good vid just the same, I'd never heard of the frog mutating worms or the crab manipulating barnacles.

      The name of the Raflesia was actually the name the 2 people who found the flower, I forgot the last part of the name, but it was pretty old for me, so it would make sense

      We are the ultimate, worldwide parasite - granting billions of animals a horrible life just to take it from them and sustain ourselves longer to infect more areas. But this host of a planet will soon die Btw i eat meat and make sausages :p

      Thank you, so much for the vlog. A vlog on "parasitic zombification" would really delight your subscribers, I'm sure :-). If you've covered this already, apologies, I've just come across your site.

    39. Ethan Q

      The Giant Corpse Flower looks like the same parasitic flower on Venusaur’s back. Fascinating. I wonder if this is where Gamefreak got the idea from?

    40. Mr Monstah

      Nice. I better make 'em all work on humans

    41. Mike Adder

      "Where did you learn so much about corpse flowers"?? "I heard it through the grapevine"

    53. The normal Gamer

      What if a parasite barnacle manages to get into a human when they are swimming?

    54. Maria Surio

      '' on the squeamish side'' me:wot da HELL you think me scared of that

    55. V Ling

      That barnacle parasitic system is downright horrific.

    56. Chris Chapel

      Fun fact: humans are parasites. We milk maple trees for their tree sap (their blood) to make maple syrup.

    62. The AnotherMysteryoso

      Corpse flower to me represents a deceiving person. Corpse flower is beautiful looking but its inside stinks. Like a girl who is beautiful but evil.

    63. Phazelight

      Thats tragic can you imagine being a creature infected with something that occasionally has sex in your mouth
