Hello and Feliz Navidad to everybody, I know, because somebody told it here, that the reason why Cipraeidae and other families looks so glossy is the continuous contact between the shell and the body of living animal, but could anybody explain why is this contact? I think is not a locomotive reason, but what then? Something phisiological like better breathness? Mimetic reasons? Just to astonish the observer? Thanks for your time. From a stormy (unbelieveable!)
