Identify this Star

[jdhoover]

Can anyone help me identify this star? I found it in my sump this morning. It is a little under 0.75" (19 mm) across, and has a 4 arm symmetry.

Asterina star.

There's lots of different opinions out there regarding these things, but I for one don't trust them at all. :thumbdown

Yeah, figured it might be, but I'm used to the little ones a quarter inch in size with differening arm lengths. This one was so much bigger, and the symmetry of four arms wasn't what I was used to seeing.

Thanks for the answer, I don't trust them either...
