YMMV: The Most Extreme

  • Critical Research Failure: In "Speed", the earthworm is stated to be "the fastest thing on no legs". That title actually belongs to the black mamba.
  • 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!
    • "Body Snatchers": Toxoplasma, hands down. No wonder it won in this category.
    • The fate of the female sea louse in "Mothers"; she gets dragged into a cavern by the male, who pretty much rapes her, gets pregnant with practically a thousand squirming babies who eat her alive from the inside out and then burst out of her, killing her in the process.
  • Squick:"Gross Outs".
  • Tear Jerker: In "Mothers", the fate of the mother octopus. She starves herself for months keeping her eggs safe and when they hatch she's so exhausted that she can't defend herself when a predatory fish arrives. And she only won number two.
