Not surprisingly, eh?
I found things (rather large) that I am quite sure that I neither knowingly put in there, nor have seen in the past. I found a 1.5 inch “hairy” crab. Will identify him later today. I did try to research another occupant, but am up against the wall. It is an oval shaped, 1.5 inch solid purple (plum), flat organism. It appears to have a head end and the edges “undulate”, however, this is not the means of locomotion. It slides along like a snail. On it’s back is a closed, slit-like orifice similar to the mouth of an anemone. In fact, at first I thought it was an anemone, however, after prolonged exposure to the light, it beat feet into a hole.
