I have long wanted a half cut nautilus shell but have resisted the temptation until now, when I realised that many online shops have stopped selling them because of concerns about the species being under threat, though not yet listed as endangered. I did make sure that I bought from a supplier which states that it only buys from approved sources.
Having survived relatively unchanged for millions of years, nautilus are often considered to be "living fossils”, indeed ammonites are a related extinct species.
When seen from the top, the natural shell is darker in colour and marked with irregular stripes, which makes it blend into the darkness of the water below. Conversely, the underside is almost completely white, making it indistinguishable from brighter waters near the ocean’s surface. Whilst the shells frequent waters around 300m below the surface, the shell is capable of withstanding pressures down to 500m.
As the nautilus matures its body moves forward, sealing the chamber behind it. The last fully open chamber being used as the living chamber.
I'm not happy with the lighting in this shot - the shell is much more beautiful in reality.

This is a nautilus shell that I photographed this month at a photo club workshop in San Diego. One of the members brought this beauty in.
Lighting stuff: I placed the shell on a mirror, and then used side lighting because I wanted to create she shadows that reveal shapes and texture. Lit with a YN560 III in an 8.6 inch Lastolite soft box positioned at camera right. Fill light came from a mirror on the left. I used a black paintbrush in Photoshop to cover up any distracting elements in the background. The flash, in manual mode, was triggered by a Yongnuo RF-603N.
I find sea shells to be beautiful objects from nature, and have photographed quite a few of them over the years. Other shells that I have photographed are in my creatively named Shells album. www.flickr.com/photos/9422878@N08/sets/72157626043932290

Nautilus repertus
Nautilus macromphalus
Allonautilus scrobiculatus
Nautilidae. Sunshine City Aquarium, Ikebukuro, Tokyo, Japan. 池袋
Nautilus Cenoceras Inornatum, from Whitby, Yorkshire, England.
185 Million Years Old, Middle Jurassic
Measurements Approx.
Height - 12.1 cm
Width - 7.4 cm
Length - 11.4 cm
Nautiloids are primitive, marine cephalopods that possess a shell. Straight (like an Orthoceras), curing, or loosely or light coiled calcium-carbonate shells, divided into a chambered phragmocone and a living chamber. The chambers are connected by a tube (siphuncle)
Nautiloids had heads with well-developed eyes, and gasping tentacles. They swam by squirting water out of the body cavity.
Cenoceras is an extinct genus within the cephalopod mollusk family, Nautilidae, which in turn makes up part of the superfamily Nautilaceae.
