Barnacle (Mouth Animation)

Fake Xen Science made by me:

The Xenian Barnacle is a stationary barnacle like organism that lives in Xen and can be found on rocks. The Barnacle spreads with small spore-like eggs that soar on the air of Xen and the eggs fertilize when in contact with a surface, but the eggs are few, making the barnacles not as common as you think. Barnacles will exhibit a behavior called “fog eating” where they will open their mouths and suck in nutrients from the aerial microbes around it with its tentacles. These tentacles are also used to release their spore eggs.
