Caption

Nautilus shell layers. Coloured scanning electron micrograph (SEM) of layers in a nautilus shell. Here, the shell in a young nautilus (stepped surface) has been covered by a thicker layer as the animal grew. The interior shell layer in a nautilus consists of a composite material called nacre (also known as mother-of-pearl). This material is mostly a form of aragonite, a calcium carbonate mineral. Nacre has a very high tensile strength due to a combination of soft organic layers and hard inorganic platelets of aragonite. The nautilus is a marine mollusc related to the octopus and squid (all are examples of cephalopods). It has a spiral shell divided into many chambers, of which the animal inhabits only the outermost. Magnification: x133 when printed at 10 centimetres across.
