Description: Some say that the golden spiral can be found all around in the nature which can be constructed as a Fibonaccy spiral Contrary I could hardly find any snail shell images with those proportions This image shows three other logarithmic spirals next to the well known golden spiral that I could find way better One of them has the proportion of the nautilus shell discussed herehttpswwwgoldennumbernetnautilusspiralgoldenratioThe other two also have systematic proportions However the bottom left one has quite a natural look its proportions were not constructed upon the golden ratioMathematical functions are included in the file if you want to plot them as parametric curvers
