Friedhelm Fischer. It’s a macro time-lapse of a simple land snail yet as it is so close up it does somewhat resemble the nightmare alien of the title.
What was most fascinating for me was watching the tentacles curl out and retract. The upper set are called ommatophores (just call them eye stalks, it’s easier). The lower set help the snail smell itself along to its next meal. Absolutely fascinating footage!
