Emporer Nautilus aka Chambered Nautilus. "When seen from above, the shell is darker in color and marked with irregular stripes, which helps it blend into the dark water below. The underside (shown here) is almost completely white, making the nautilus indistinguishable from brighter waters near the surface. … The nautilus shell presents one of the finest natural examples of a logarithmic spiral.” Wikipedia. Paul Humann, et al, Reef Creature Identification (2010), page 405.

Nautilus

  • Emporer Nautilus aka Chambered Nautilus. We were told that each Nautilus diving day the Nautiluses are brought up slowly from 200 meters. After the dive, they are returned to that depth and released. Paul Humann, et al, Reef Creature Identification (2010), page 405.
  • Emporer Nautilus aka Chambered Nautilus. Divemaster Kostas reaches around an eel to grab a Nautilus raised from 200 meters below. The Nautiluses (and eel) were lured into the cage by a frozen chicken lowered and left in the cage overnight. We were told that this dive is environmentally sustainable and does not harm the Nautilus. Occasionally an eel hitches a ride along with the Nautiluses, as it did on our day of diving. See Paul Humann, et al, Reef Creature Identification (2010), page 405.
  • 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. Paul Humann, et al, Reef Creature Identification (2010), page 405.
