Echinoderm locomotion

At the beach we found some sea urchins.  They're good to eat but it takes a bit of doing.

We didn't eat them.  We just played with them for a while and exclaimed at how they wave their little spines around.

Then we set one down on the rocks and it made a break for it.  This is at 8X speed.

I love that last move the little spiny guy made: PLOP!

Thanks again for all the wonderful glimpses into your world!
