How to read this map

The map plots a sample of 1,172 of the 1,172 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 18 of the 18 countries or areas with records; the areas absent from the sample hold 0 records in total.

10 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.
