The tender inner meat of the sea urchin can certainly be eaten, and is sometimes incorporated into sushi. The shell and spines are inedible.

BUT if you have a sea urchin do not have any crabs in there, because my sea urchin killed one, and almost killed another one by taking its claw off. :(
a blue tuxedo sea urchin
It urges the sea to adapt to IT! The litle urchin urger.
Spines of the sea urchin can cause injuries of the skin.
