Beneath sea urchins’ exterior spines, rounded skeletons called tests are jewels of color, texture, and symmetry. There are hundreds of urchin species, and they’re found in every ocean on Earth, from the intertidal zone to more than four miles below the surface. In 2018, Anders Hallan, a research associate at the Australian Museum in Sydney, began photographing urchin skeletons that had washed up on beaches or been collected by divers and those on fishing or research vessels.
