Strange Marine Creature
This strange creature was filmed underwater by drillers in the deep ocean. It is called Deepstaria enigmatica. It looks like an underwater dementor.
They modeled the animation for the dementors by making marionette versions and putting them in fish tanks. This made their movements more fluid and tons more terrifying.
