Finally got around to covering parasites. Damn, you're slow. Just from the first parasite you listed, I'm already confident I've heard of every one on the list. I'm hardcore on science. Meanwhile, I'm also sure you left off the worst. Humanity.

Couldn't male genitalia be classified as parasitic? I mean think about it 1: They demand a constant supply of nutrients 2: They take over your brain and make you do things 3: They tend to make it very easy to "take care" of them

What about the Emerald Cockroach Wasp aka the Zombie Wasp? It’s a wasp parasite species that find cockroaches, stings it to paralyze, and manipulates it’s mind to letting the wasp lay it’s larvae inside the cockroaches stomach. Over time, the larvae feed on the cockroaches nutrition and eat everything till their all grown up. I don’t know what the male does, but the female does all of this and continues to do so.
