A visual exploration of Earth's Shell Forms which uses both x-ray and traditional reflective-light color photos, often compared or blended together. It focuses most on the classic Mollusc shapes, but also delves into the recent Anthropocene shellforms taking over the oceans. Discussion of shell parts, colors, textures, families, and taxonomy. Does not shy away from ecological, mythical, and philosophical implications, which are given from an outsider universalistic perspective.
