Cut Nautilus Shell Polished
This shell has been sliced in half to reveal its delicate inner chambers.
The wonderfully shaped nautilus shell is decorated with brown tiger like stripes in its natural state.
This specimen reveals an amazing array of glistening colours now the outer layers have been removed and polished to show the natural mother of pearl beneath.
Related to the octopus, squid and clam, the spiralled nautilus shell is divided into chambers with the animal occupying the outermost chamber.
A newly hatched nautilus begins life with about four chambers and develops an average of 30 chambers by adulthood. The inner chambers are filled with gas and help the nautilus to maintain neutral buoyancy. By adding liquid to the chambers it is then able to dive.
The nautilus is also considered to be a "living fossil" as they have undergone little change in over 400 million years.
They dominated the ancient seas before the rise of fishes and appeared about 265 million years before the first dinosaurs. In prehistoric times there were about 10,000 different species of the nautilus, but only five species have survived to the present day.
Common to the Western Pacific.
(The images were taken at Lyme Regis in Dorset on a stretch of exposed ammonite fossils).
Sold as one cut half of a nautilus shell.
Size: approx 16 cm across (6.25")
Please note: It is inevitable that some of the delicate inner chamber walls may have some small damage caused through the cutting process, however we will always endeavour to send our best examples.
This species is currently under threat, although not currently listed by CITES as being endangered, we have taken the decision to stop selling these beautiful shells.
On occasion we are able to obtain old stock, if you would like to be notified when available again, simply drop us an email.
