Centrostephanus rodgersii and Heliocidaris erythrogramma

A combined-species resource for projects that address long-spined and shortspined sea urchins through harvest, processing, and ecosystem restoration.

Red-spined sea urchin, Heliocidaris erythrogramma, representing one species in this combined profile

Combined management context

Some control and processing programs work across both species. This combined record demonstrates that a Convex resource can represent a practical cross-species topic without changing the Sanity project-page model.

Why a combined resource is useful

  • Shared harvest and processing infrastructure
  • Control programs paired with ecosystem restoration
  • Comparison of responses across invasive and overabundant native contexts
