In March 2026, Ecuador proposed moving the scalloped hammerhead shark to Appendix I of the Convention on Migratory Species at a meeting where Pelayo Salinas de León of the Charles Darwin Foundation presented satellite‑tagging data showing that 8 out of 10 tagged sharks migrated from the Galápagos Islands to Panama to give birth. The species is critically endangered, yet locally abundant at Darwin and Wolf islands, with densities reaching 150 sharks per hectare at peak.
