Want a Hug?

Believe it or not most visitors to the touch pool at the Denver Aquarium  take me up on the offer and get a thrill out of their hug.  Why do these sea urchins gently squeeze our finger between their spines when we give them a chance?  I’d tell you, but I’m afraid that if I look it up I’ll find out that the “hug” is  an unfriendly reflex of some kind, and that would spoil everything.
