These are just incredible.

As far back as the ancient Greeks, the shell of the chambered nautilus has been a symbol of perfection. This shell can be described mathematically as a logarithmic spiral. The nautilus is a slow moving Cephalopod and considered primitive when compared to its faster moving relatives such as the squid. They have an external shell, but do not have lenses in their eyes. Nautiluses have been on the planet for 500 million years. Nautiloids and ammonoids were once one of the dominant groups in the oceans, both in terms of number of species and biomass. The remaining seven species are considered living fossils. The external shell of these animals provides both protection and rigid open spaces that can be filled with gas for buoyancy.
