Tentacle
Exhibiting characteristics of both the plant and animal kingdoms, it is speculated that the immense specimens reported for this highly sensitive xenosuctorian are a function of the Terran atmosphere. Lacking eyes, ears or other animalian sensory organs, h. sensitiva is nevertheless capable of detecting and targeting emitters of motion and sound in its immediate vicinity, by some process which is incompletely understood. The Tentacle, like some orchids and bromeliads, is most likely an epiphyte, deriving nutrients from the air and detritus; which theory is supported by the observation that h. sensitiva does not appear to eat what it kills, but conceals its prey beneath its root mass and absorbs the byproducts of decay. Stay quite in the presence of tentacles, and/or distract them if you want to stay alive.
