GBIF occurrence records for Inachus phalangium, mapped and tabulated by country.
Distribution map plotted from GBIF.org occurrence records; basemap Natural Earth 110m · GBIF records CC0 / CC BY; Natural Earth public domain
3,894 georeferenced occurrence records with coordinates are published for Inachus phalangium through GBIF, from 23 countries or marine areas. This page maps those records and lists where they come from. Occurrence records reflect where people have looked as well as where the species lives, so well-surveyed coastlines are over-represented.

How to read this map
The map plots a sample of 3,000 of the 3,894 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 17 of the 23 countries or areas with records; the areas absent from the sample hold 13 records in total (Denmark, Cabo Verde, Germany, Egypt, Svalbard and Jan Mayen, Senegal).
101 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.
