Salmacis sp.

Sea urchins are covered in spines in order to protect themselves from enemies. 

But did you ever imagine that hidden beneath those spines is the most beautiful bone structure you’ve ever seen? 

These unpainted, naturally colorful sea urchins have been enclosed inside acrylic resin in order to preserve the fragile bones. 

Then our artisans carefully smooth them into an oval shape, providing a unique perspective from which to observe the bone structure.
