Name: Nautilus pompilus
Selected shell from approved sources for crafts and interior decoration. This “Triple A” specimen quality nautilus shell has been cut through its axis to reveal its internally divided chambers, whilst retaining the characteristic striped markings on the external half. Even with highly experienced operators the internal septa of the nautilus can be damaged during cutting and onward transport.
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. Converseley, 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.

Concern has been expressed over suspected dwindling numbers of Nautilus.
As the cephalopods generally live at depths of between 100m and 500m it is difficult for scientists to absolutely quantify numbers in the wild. However, anecdotal evidence form fishermen and comparison of number counts and size of specimens from fished areas and protected marine environments suggest that in some localities of the world overfishing is becoming a problem.
Whilst the lifecycle of Nautilus is not fully understood, it is known that the creature can take up to ten years to reach sexual maturity and even then the species does not produce a free swimming larval stage, making it difficult for it to re-colonise areas should numbers become depleted.
We will continue to monitor the situation, and at all times work within agreed International Conventions and the Law of exporting countries.ACTUAL AS SEEN: The image shows the EXACT unique specimen you will receive. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device.
