'Captain Nemo dives again' -digital art George Roberts March 2024. |
The Nautilus both extant and extinct, are characterized by involute or more or less convolute shells that are generally smooth, with compressed or depressed whorl sections, straight to sinuous sutures, and a tubular, generally central siphuncle. Having survived relatively unchanged for hundreds of millions of years, nautiluses represent the only living members of the subclass Nautiloidea, and are often considered "living fossils" -Wikipedia
The shells follow the mathematics of a logarithmic curve. All but one of the above were generated as fractals created in the software INCENDIA.
