Nature is amazing.
Here are some more photos from the CAS.The California Academy of Sciences includes a Natural History Museum, Morrison Planetarium and Steinhart Aquarium all in one location. The back of this turtle is exquisitely patterned. The black widow spider is near the top of the jar (just threw this in for the "ick" factor). Watching the penguins swim in the water with all the light and shadow explains much of their hi contrast patterning. Dappled spots and stripes mimicking the shadows of tall grasses and trees is so clever. I wonder if Buckminster Fuller ever stared at a turtle shell like this and imagined his geodesic dome?
