The back of a turtle is a combined pattern of pentagons and hexagons: a hex-pent matrix. As the turtle grows, each individual hex-pent pattern adds a new ridge in the outer edge. This is apparent when you closely examine the turtle’s back.
The process is analagous to how I have provided for the organic growth of geodesic hex-pent domes, which could be done just by inserting successive caulkings or layerings around each hex-pent module.
