GBIF occurrence records for Heniochus monoceros, mapped and tabulated by country.
2,080 georeferenced occurrence records with coordinates are published for Heniochus monoceros through GBIF, from 50 countries or marine areas.

How to read this map
The map plots a sample of 2,080 of the 2,080 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 50 of the 50 countries or areas with records; the areas absent from the sample hold 0 records in total.
26 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.
