About this map. Scroll or pinch to zoom, drag to pan, and click a dot to identify the species. The 1,837 dots are real occurrence records pulled from GBIF, the Global Biodiversity Information Facility — an aggregator of museum specimens, scientific surveys and verified citizen-science sightings. Treat them as a guide to where a species lives, not exact spots: many records are georeferenced to a locality centroid (a nearby town or river mouth) rather than the precise catch site, some are historical or low-precision, and the occasional point may be a misidentification — several of these fish are hard to tell apart, and records filed under a species that has since been split may refer to any of its descendants. Some species have few public records — a sparse map is honest, not an error. No coordinates are invented.
