Do Starfish Have Feelings?

Dan took some photos of his saltwater tank for a contest. (No one ever wins contests, but I think he is desperate for someone to enjoy his tank as much as he does.) So I thought I would post them. Tank Update: We had a shark egg (called a mermaid's purse) and it actually hatched. We now have a little bamboo shark that lives under a cave-like rock. He only comes out at night but fortunatley the rock is in front of the tank so we can watch him sleep. So far he has not eaten any of his roommates. I wish I could say the same for a little crab we bought. We got him because we are getting a bunch of genetically mutated starfish on the sides of the tank and allegedly he eats them. Well... we had a pair of large sand starfish that were in love with one another and gave eachother piggy back rides constantly. Unfortunately, the crab ate one of them and now the other one is forlorn and we think a little cranky.
