The Most Extreme/YMMV
- Nightmare Fuel: The episode "Horrors", epsecially the winner (parasitic worms)- some can penetrate through your skin, and then live inside you!
- In "Odd Couples", the Greenland and Pacific sleeper sharks are sluggish in cold water, so a small bioluminescent bloodsucking copepod attaches itself to the eye and acts like a fishing lure (which also blinds the shark). Yep, having a parasite for an eye!
- The snapper and the tongue biter louse definitely qualify.
- "Body Snatchers":Toxoplasma, hands down. No wonder it won in this category.
