You could be right, but most creatures like the ramoras aren’t agressive. I mean those things attacked anything that moved…as a parasite would. You think of the type of creatures they resembled ticks, fleas, those types of creatures feed off of the host directly.
Even if you want to link them to spiders, the reason why spiders and most animals have venom ; is to catch and render helpless live food, food that can either fight or escape…yes it aids in disgestion, but I believe that’s a side effect of the venom.
If you look at say a fly, that does use it’s saliva as a digestive chemical; it does so on dead material; it wouldn’t work on prey that could get away.
Yet these creatures are fast, strong and hunt in packs…one of the guys mentioned that he felt they were trying to drag him away…ok assuming he was correct, where would they be able to drag prey living or dead unto a living creature…unless they managed to either find a natural occuring spot or borrow one on it’s body?
Which makes sense if they used their venom to weaken the creature’s skin…then the army’s weapons should have been able to penetrate it…
Sorry for the hijack and I realize we can discuss this to the cows come home and I’m hardly expert enough to defend my position beyond the basics of biology; but I found it inconsistent with how nature should work…even if it’s alien and it bugged me…it seemed they had great idea, but ignored the rules of nature to make it work…which would be ok; if they ignored all the rules or applied them consistently.
As noted, they aren’t the first to do this and this is hardly the most horrible; but it bugged me never-the-less.
YMMV…of course.

All good points - but what if these creatures simply feed on the ramoras and genuine parasites? They cling to Snookums, and go after other animals that also live on him. In other words, Snookie-pie has an entire food chain living on his skin. Implausible, sure - but it explains the presence of “parasites” that are too aggressive to make sense as simple ramoras, but too feeble to feed off Snookums directly.
