How to read this map

The map plots a sample of 3,000 of the 9,815 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 3 of the 6 countries or areas with records; the areas absent from the sample hold 4 records in total (Panama, Costa Rica, Peru).

51 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.
