How to read this map

The map plots a sample of 3,000 of the 30,315 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 29 of the 35 countries or areas with records; the areas absent from the sample hold 36 records in total (Venezuela (Bolivarian Republic of), Barbados, Saint Barthélemy, Haiti, Bermuda, United States Minor Outlying Islands).

16 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.
