Drooping Stingers

Hanging Stingers are a life form appearing in caves.

Looking like a hybrid between a sea anemone and a jellyfish they are attached to the rock ceiling, waiting for prey to be caught by their tentacles. Touching a Hanging Stingers causes poison damage.

They were officially announced on the Subnautica website. The concept art was done by Cory Strader

Behavior
Their behavior was fleshed out on this trello card.

A few key points are:
 * Damages anything live that touches it (Poison damage).
 * Target gets set as GameFlagState.Poisoned for 5 seconds (GameFlag.Set(obj, GameFlag.Poisoned, 5)
 * While poisoned, loop poison damage sound for creature, and take damage over time.
 * Smaller variants do less damage for less time (-50%), larger variants do more damage for a longer time (+50%).
 * When emissive lights on Stinger are glowing, that means the Stinger is active. After it stings a target, it becomes stops glowing for 5 to 10 seconds (random). Then it fades the glow back up over 1 second, after which time it is active again. Alternatively, the stingers could retract a bit instead of change their glow if that’s much easier.
