bought a new zoo rock and there were about 7 or 8 of these, that i could see. looked like some of them were hiding inside of the closed zoos. i picked them off just in case. i didnt think to put them in water just in case they were good, so they are all dead by now. just curious though, just in case i missed some.

I really have no idea at all! giving you a bump though.

were they moving at all? It almost looks like some kind of weird, tiny urchin.

it is hard like an urchin. but its spines are around the outside rim of the circular disc area, like a starfish....come on guys!

ok, some more ideas... maybe a tiny sponge or some kind of colonial organism, maybe a very strange egg casing?

fwiw, i have lots of zoas and don't recognise this as being anything that would be associated with a zoa predator, but there are alot of weird little things out there. you might want to post this in the zoa forum in case anyone recognises it as a 'baddie'. the thing that worries me is alot of times predators with specific prey requirements will be found in large concentrations on or near the food source. finding a bunch of these on a particular coral may be a bad sign. i don't want to alarm you though, chances are it's harmless.- but you nevah know-

still looks most like a tiny little urchin to me. i really don't know.

My guess is an immature urchin. If you flip it over is there a beak or a hole directly in the center?

i cant see any holes of any kind no beaks, very strange. it does some what resemble an urchin, but i cant see how it would eat...

Can you flip it over and take another picture? Are the spines moveable?

looks exactly the same on both sides. spines do not move.

Similar things have been posted before. It's a foraminiferan and harmless. These are basically amoebaes that form a hard shell around themselves.
