Hey EmilyB I know the one you are thinking of and it's not the same one.
Someone has my copy of the Baesch atlas so I can't check that one.
If you have a Modern Coral Reef Aquarim Vol 4 you will see an almost exact picture of your starfish.
I also believe the one you are thinking of is a sub-temperate species.
Even if you disagree with me, It is still in that family. It has the small pores on it's body that are indictive of this family. If I had a scanner I'd send you what I have,but I don't. If you search on google images you'll see a picture of it. Unfortunately the website is no longer active.
I'll see if it can be ordered through any of the suppliers I know.
