Note on the data: conservationStatus 'vulnerable' is a judgment call — sources conflict between Vulnerable and Near Threatened depending on region/assessment vintage, and neither dive-travel source addresses conservation status directly. Worth confirming against the current IUCN assessment before publishing.
