Where Bluestriped butterflyfish has been recorded
GBIF occurrence records for Chaetodon fremblii, mapped and tabulated by country.
2,876 georeferenced occurrence records with coordinates are published for Chaetodon fremblii through GBIF, from 3 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 2,876 of the 2,876 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 3 of the 3 countries or areas with records; the areas absent from the sample hold 0 records in total.
13 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 confirmed locations has the Bluestriped butterflyfish been recorded at?
The species has 2,876 georeferenced occurrence records mapped across 32 distinct locations, all published through the GBIF database. These points give fans a concrete picture of where the fish has actually been observed.
In how many countries or marine areas does the Bluestriped butterflyfish occur?
Records place Chaetodon fremblii in just 3 countries or marine areas, though the apparent spread depends heavily on where researchers have conducted surveys rather than the fish's true range.
Why do some coastlines show up more often in Bluestriped butterflyfish sighting data?
Occurrence records track where people have looked, not just where the fish actually lives, so heavily surveyed coastlines naturally appear over-represented in the dataset. A sparse count for a region doesn't necessarily mean the species is absent there.
How many records were actually used to build the distribution map?
All 2,876 georeferenced records were sampled for the map, though 13 inland records were excluded since they fall outside the species' marine habitat.
What identifier do I use to look up Bluestriped butterflyfish records on GBIF?
The taxon key 2385500 is the unique GBIF identifier for Chaetodon fremblii, letting you pull up every published occurrence record for the species in one query.
