Moved a rock and this was on the under side:
It seems to be some kind of sea slug or? It moves fairly quick. In the time it took to pull out the phone it crawled to this gap in the rock. It’s pretty big- about an inch wide and two inches long- kind of oval shaped. Anyone know what this is and if this is a good or bad creature?
