Vintage Zebra Sea Urchin Shell with Spines – Large Marine Specimen, 9"

Rare. Striking. One of a kind.

Bold zebra-striped spines radiate outward from a perfectly formed shell — this is the Prionocidaris baculosa, one of the most visually dramatic sea urchins in the natural world. This vintage specimen is large, intact, and in remarkable condition, with the characteristic alternating dark and pale banding that gives the species its name.

A piece like this belongs on a shelf, a mantel, or inside a glass cloche — somewhere it can be seen, studied, and admired. It is equally at home in a naturalist’s cabinet, a coastal living room, or a curated collection of ocean curiosities.

Only one available.

Our Commitment to the Ocean

At SASTIMOS, we are proudly pro-conservation and committed to the preservation of our oceans and marine ecosystems. We do not source newly harvested coral or protected marine life.

The coral and ocean specimens in this collection are vintage pieces — acquired through legal channels before today’s stricter marine protections were widely established. Rather than see these rare pieces discarded or forgotten, we believe in giving them a purposeful second life, where their beauty can be appreciated and preserved for generations to come.

We believe in wasting nothing the natural world has already given us — and in protecting everything that remains.
