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.

Step 1. Go to Google Step 2. Search this keyword: 123moviesdaily Step 3. Enjoy! 4 Parasites Too Creepy to Exist It is a curious thing, the death of a loved one. We all know that our time in this world is limited, and that eventually all of us will end up underneath some sheet, never to wake up. And yet it is always a surprise when it happens to someone we know. It is like walking up the stairs to your bedroom in the dark, and thinking there is one more stair than there is. Your foot falls down, through the air, and there is a sickly moment of dark surprise as you try and readjust the way you thought of things.

By definition a parasitic relationship occurs between to different species. So no.The more detailed definition of a parasite also reduces the host's "fitness". What is meant with fitness here is not how sporty a person or animal is; rather biological fitness describes how likely a population or individual is to pass on their genes. Since having children is detrimental to passing on one's genes - quite the opposite I'd dare say - a fetus doesn't fit that criteria for being a parasite either. There are a couple more things, but the short answer is: no, a fetus wouldn't be considered a parasite.

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

I find it fascinating how, in... recent-ish times, we've gone from thinking that horizontal gene transfer only happened in archaea and bacteria, to discovering plants and even some animals that do it or have done it, too!
