Maybe you got this before, but I think it got lost because I didn't get it my own self. (We've been having a bad-hair-day in Cincinnati, 10 inches of snow on the ground and five more predicted, and blowing and drifting, and doing all sorts of other mean things.) But what I wanted to ask was in regards to the discussion of colors on shells. The question is: Do mullusks themselves perceive color? If they don't, the idea of color being a sexual stimulant goes out the window---into the snow. Do things that prey on Mullusks perceive color? Can color (at depth) be perceived in any other way than by eyesight? Art
