Baby Starfish??

[Jammerwocky]

Could this be anything else besides a baby starfish???

I'm so excited, and really hope it is!

It looks like an Asterina starfish to me - it's probably full size or just about full size (it looks like it might have some growing room on some of its legs still, but that's about it).

Edit: They're a common hitchhiker, and they're know to reproduce like crazy (some people consider them pests because of their reproduction, others think they might eat corals - if they do, it might be a species specific thing or a "you have too many asterinas and should probably remove some" thing).

Second, it is a Asternia, most have partial or missing limbs, never had more than a few, my favorite hitcher, is a "Micro Brittle Star"...

They are considered a hitchhiker that some claim can eat zoas…they will multiple quickly and you will which you did not keep them,…I had a couple and within a week or so there were 50 where it got out of hand and could not keep up…they will eat coralline algae quickly…

L just found one of these on the glass. I tried and failed to capture it. I think that I see two more of them on my rocks.
How do I get rid of them ? Is there a fish or invertebrate that will eat them ?
