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.

A 3D model of some Hanging Stingers can be found here.

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.
