Today I came across this specimen found on the shores of Samos Island Greece. Whatever it is it was apparently eaten by a sea star! Does anyone know what species the skeleton belongs to?

I think this is the exosceleton of a crab type that lives in sand. I think they change shell as they grow like some insects. It was seriously brittle right?
If indeed freshwater crab that made its way to the spot it was found... genus potamindae? id imagine there are hundreds of species/subspecies but only a few in Samos maybe?

Whatever it is, cool find!
Thanks for the input! Turns out it’s the Heart Sea Urchin! And my story of the sea-star death was misinformation. It is simply the design it is born with.
