Where Chain pipefish has been recorded
GBIF occurrence records for Syngnathus louisianae, mapped and tabulated by country.
9,446 georeferenced occurrence records with coordinates are published for Syngnathus louisianae through GBIF, from 7 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 9,446 records, deduplicated to a half-degree grid, so dense areas do not merge into one blob. The sample covers 2 of the 7 countries or areas with records; the areas absent from the sample hold 5 records in total (Bermuda, Canada, China, Spain, France).
52 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 Chain pipefish occurrence records are published on GBIF?
There are 9,446 georeferenced records with coordinates available for Syngnathus louisianae through the GBIF database. These records span 7 countries or marine areas and are drawn from a pool of 3,000 records sampled for the distribution map.
How many distinct locations does the Chain pipefish distribution map show?
The map plots 41 individual locations across the 7 countries or marine areas where records have been logged. A small set of 52 inland records was excluded from the mapping because they fall outside the species' expected marine or estuarine habitat.
Why does the Chain pipefish distribution look uneven across coastlines?
Occurrence data partly reflects sampling effort rather than true abundance, so heavily surveyed coastlines naturally show denser clusters of records. This means the map can over-represent well-studied regions while under-representing areas where fewer people have looked.
What GBIF taxon key should I use to pull Chain pipefish data?
The GBIF taxonKey for Syngnathus louisianae is 2332958. You can use that identifier in the GBIF API or website to retrieve all 9,446 georeferenced occurrence records in one query.
Does the Chain pipefish distribution page include every single record?
No. The map visualizes a sample of 3,000 records out of the full 9,446 published, and 52 inland records were deliberately omitted. The underlying tabulated list, however, still accounts for records from all 7 countries or marine areas represented in the dataset.
