Where Black-axil chromis has been recorded
GBIF occurrence records for Chromis atripectoralis, mapped and tabulated by country.
5,491 georeferenced occurrence records with coordinates are published for Chromis atripectoralis through GBIF, from 44 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 5,491 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 38 of the 44 countries or areas with records; the areas absent from the sample hold 26 records in total (Micronesia (Federated States of), Réunion, Wallis and Futuna, American Samoa, China, Kiribati).
24 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.

Frequently Asked Questions
How many countries or marine areas has Black-axil chromis been recorded in according to the distribution page?
The page documents occurrences across 44 distinct countries or marine areas, drawing from 5,491 georeferenced records available through GBIF.
How many mapped locations does the Black-axil chromis distribution page actually display?
Although nearly 5,500 records exist in the database, the map visualizes 284 distinct locations using a sample of 3,000 records to keep the display readable.
Why do some coastlines show up more heavily in Black-axil chromis occurrence data?
The records reflect not only where the fish actually lives but also where researchers and divers have focused their surveys, so well-studied coastlines naturally accumulate more entries.
Why are 24 inland records omitted from the Black-axil chromis distribution map?
Those inland points are excluded because they are almost certainly data-entry errors or mislabeled coordinates, since this is a strictly marine reef species.
What is the GBIF taxon key for Black-axil chromis distribution records?
The species is catalogued under GBIF taxonKey 5212173, which links all 5,491 georeferenced occurrence records to the correct Chromis atripectoralis entry.
