There are many examples of the Golden Section or Divine Proportion in
nature.
Below are just a few:
The eye, fins and tail all fall at golden sections of the length of a dolphin's body.
The
dimensions of the dorsal fin are golden sections (yellow and green). The thickness of the dolphin's tail section corresponds to
same golden section of the line from head to tail.
The eye-like markings of this moth fall at golden
sections of the lines that mark its width and length.
The spiral growth of sea shells provide a simple,
but beautiful, example . . .
