Sola Cube: Sea Urchin (Salmacis)


A Whole New Uni-verse

You may have seen uni on the menu of a sushi restaurant. But in the wild, these prickly sea urchins are covered in spines to protect themselves from enemies. And hidden beneath those spines is an unseen universe of breathtaking bone structure.

These vibrant, naturally colorful sea urchins have been enclosed inside acrylic resin in order to preserve the fragile bones. Artisans then carefully smooth them into an oval shape, providing a unique perspective from which to observe the bone structure.
