(I just wanted to say this is my take on the creatures, I do not own the drawings and they belong to a Manga called Tomahawk Angel and I dont know the story line so this is my own guess.)

Years had passed since the apocalypse happened, creatures spawning all over the plain. Humans tried to fight back but it only did so much...

Clittorith is a stalker like predator, it will lock its eye's on prey and hunt it for days, pretending now to notice it only to suddenly jump it whenever it can. There ravenous carnivores who will stop at nothing to kill its prey but often enough they get possessive of certain creatures like humans. If a human feeds it or shows affection the Clittorith will get possessive over that human. The stalking gets more intense and sometimes they like to spread there tentacles that guard there lips and latch onto your arm to suck on it, like asking for more affection.
