The carnivorous plant litters the bestiaries of fantasy and space opera gaming, likely due to its association with early 20th century adventure fiction, from which nearly all RPGs eventually draw their core inspiration from. The carnivorous plant typically shows up in jungles, where it signals that the jungle is so hostile and so predatory, that even the plants try to eat you. They also signal a truly alien landscape, because while carnivorous plants exist, they absolutely do not do so on a scale that could threaten a jungle hero.
Functionally, they typically behave like traps rather than monsters, though some will simply act like immobile monsters that lash out and grab people and try to drag them to its sap-dripping maw. Of course, some just haul themselves out of the ground and go rampaging after their prey, but that’s not what interests in this particular post, because what I’m looking for, a the end of the day, is a sessile predator, because, in part, I want to explore the idea of space monster as trap.
How realistic is a sessile predator? Well, of course, carnivorous plants exist, but they tend to rely on natural geometry and stickiness to trap something no more intelligent than a mayfly and slowly dissolve it. Heroes tend not to be that stupid, and so we need things like grabby tentacles and chomping mouths to actually make this work. Do those exist in biology? Sure! There are, for example, carnivorous sponges, but the best example are probably sea anemones. So all we need to do is extrapolate some sort of larger version of these. This means that what I’m talking about probably isn’t a “plant” at all, but “Land Anemone” doesn’t quite have the same ring to it.
