Found a few of these in the rock. Any idea?

I've seen 3 of these in 2 different rocks. I don't have a clue what it is, in sure someone on here does. Kinda hard to see. It's dead center of the pic and looks like tiny thin legs sticking out. (Legs is all I've seen). Some kind of worm maybe? Hopefully it's harmless.

Hard to see on my phone but if you're referring to the thing in the center of the pic looks like arms of a brittle starfish.

kind of hard to see but looks like a small serpent star fish going by the markings good part of your CUC

Yes. Mini brittle starfish. They don't grow much larger than that and they are harmless.
