How to read this map
The map plots a sample of 3,000 of the 29,739 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 18 of the 35 countries or areas with records; the areas absent from the sample hold 87 records in total (Belgium, Algeria, Greece, Dominican Republic, Sri Lanka, Malta, Venezuela (Bolivarian Republic of), Brazil).
147 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.
