Star YouTube scientific illustrators AsapSCIENCE often take their cues for their videos from suggestions in the YouTube comments – so I’d like to personally thank whoever suggested this gem.

Parasites are just disgusting, and there’s a chance that you have one penetrating your bodily defenses right now. Somehow, even cute illustrations can’t lessen the creepiness of an anal worm.

Gross.
