Where Margined coralfish has been recorded
GBIF occurrence records for Chelmon marginalis, mapped and tabulated by country.
1,726 georeferenced occurrence records with coordinates are published for Chelmon marginalis through GBIF, from 4 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 1,726 of the 1,726 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 4 of the 4 countries or areas with records; the areas absent from the sample hold 0 records in total.
9 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 georeferenced records of Margined coralfish are published on GBIF?
There are 1,726 georeferenced occurrence records with coordinates available for Chelmon marginalis through the GBIF database. All 1,726 of these records were sampled and included in the distribution map.
In how many countries or marine areas has Margined coralfish been recorded?
Occurrence data places Chelmon marginalis across 4 countries or marine areas. These records are tabulated and mapped by country on the distribution page.
How many distinct mapped locations show Margined coralfish sightings?
The distribution map displays 125 individual mapped locations where the species has been observed. A small number of inland records (9) were excluded from the mapping since the fish is marine.
Why might the recorded distribution of Margined coralfish look uneven?
The pattern of records partly reflects sampling effort rather than true range, meaning heavily surveyed coastlines appear more populated than less-studied ones. So the map shows where people have looked as much as where the fish actually lives.
