The entire body of a sea urchin is what researchers are now calling an “all-body brain,” with neurons that function as a brain throughout its anatomy. (www.popularmechanics.com)

These guys always made me feel uncomfortable. I would collect and eat them, and the remains would run away afterward.

Er...I...um...what‽

It’s true! I would collect them in a pail from the tidal pools as a child. I would crack them open with whatever I had available and eat them, and the halves would still be running around on the ground after I discarded the rest.

The parts of urchin, the remains, they would skitter around and bunch up in one corner of the yard trying to get away like they didn’t realize they’d been eaten yet even though there was nothing left inside.
