How to read this map
The map plots a sample of 3,000 of the 4,901 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 68 of the 87 countries or areas with records; the areas absent from the sample hold 71 records in total (Kiribati, Tonga, Chinese Taipei, Mozambique, Aruba, Saint Barthélemy, Réunion, Mayotte).
91 records plotting inland were omitted: for a marine species those are almost always the holding institution's coordinates rather than a collection site.
Records show where the species has been observed and reported, not a modelled range.
