Spike Trap

Concept art

Early ingame rendering

The Spike Trap is a life form most likely belonging to the fauna of Subnautica. This is because of it's shell like base from which long tentacles extend which attack the player if he moves into range.

It was seen first on the Trello development tracker. ^[1]
