Izit attached to the rock?? you got a better pic??

[zarkon]

Not attached to any rock. Move around alot. I can't find it now.

I'll try to take a better pic.

looks like a closed up anemone .But one that's not too healthy. Better look for it and take a clearer pic just to be sure.

not very clear pix but looks like one of those sml jelly fish that usually lies in inverted position on sand bed.... used to find them at the reef outside the lagoons of sentosa.... does it hv some greenish patterns on its back?

[zarkon]

Not that I can remember. I'll try to contain it somewhere... If I can find it.

doesn't look like an anemone, can't see any tentacles, look more like transparent sponge to me.
