Sea urchins "see" the sea with their spines

Something to think about the next time you get poked by an urchin. It's one thing to get poked in the eye - how often you get poked by somebody's eye?

Super neat! I find the movement of sea urchin spines to be super creepy... and a little mesmerizing. I'll never look at them the same way again now that I know they're staring back.

Apparently... once every couple months.

Wow, that's really cool. I always supposed they just moved around by braille.
