Starfish

thanks martha

hahaha thanks--i thought it is a giant egg from a starfish cause it has a star on it.

Thank you so much for the info Marta. I thought all starfishes had 5 arms. Guess, I was totally mistaken.

All pics except the last one correspond to a type of starfish called cushion starfish (Culcita sp.). The three middle photos are the same but the part below in the starfish.
The last pic is of a sea urchin skeleton, sand dollar, I think.

I think, there are almost three species of urchins in there. It would be great if you could split it into three different spottings. That way it will be easier to identify.

Looks more like a sea urchin, than a starfish.
