Shelled Cephalopod!

 

Cousin to the Octopus, Squid, and Cuttlefish, the Chambered Nautilus is the only cephalopod that has a shell that resembles their other mollusk cousins--the "sea shells".

These shy creatures usually live in very deep water in the Indo-Pacific area and occasionally their shells float to the top and wind up on the beaches or fishermen bring them up in traps or nets.

Sometimes, scuba divers in places such as the Rock Islands of Palau where there exists sharp drop-offs to deeper water (Ngemelis Cliff, for instance), can see chambered nautilus swimming closer to the surface such that they can swim up to them and get pictures of them swimming in the open.

The nautilus propel themselves in much the same manner as their cousins--by squirting jets of water through an opening among their tentacles.

Chambered Nautilus (Ancient Squid)

The Chambered Nautilus (Nautilus pompilius) is the best known species of nautilus. The shell, when cut away reveals a lining of lustrous nacre, and displays a nearly perfect equiangular spiral. It has primitive eyes compared to other cephalopods, mostly due to the fact that they have no lens. Their eyes are comparable to a pinhole camera. It has about 90 tentacles and no suckers which is also different from other cephalopods. This nocturnal animal has a pair of rhinophores, which detect chemicals and uses olfaction and chemotaxis to find its food. From Ocean World Siam Paragon Bangkok Thailand.

About EditorDave

Living on Guam is what now "defines" me.  It was such a dramatic difference in my life and outlook on things that there's no way I'd be the same if I had remained in New Mexico or any of the rest of the U.S. Mainland.   One of the classes I took at the University of Guam was "Scientific and Technical Writing and Editing"... I did not realize at the time that this class would be setting the foundation for the rest of my working life.  I found that I *love* words and fooling around with making them work as best as possible.  I also took classes in formal linguistics at the University of Guam--and took classes in Japanese, Russian, Mandarin Chinese. These classes helped me to become comfortable with working with translations of technical material into English from other languages.  I can help folks with making their words work for the particular audience they are writing for.
