Nautilus, Palau, 2011

Emporer Nautilus aka Chambered Nautilus. We let our nautilus's float in front of us to try to coax them out of their shell. I am beginning that process in this photo. Note the shell's white bottom and irregularly striped top, as well as its "leathery hood formed from two specially folded tentacles." Wikipedia 2011.
