About this map. Scroll or pinch to zoom, drag to pan, and click a dot to identify the species. The 688 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 — queried for both each fish’s current name and its older genus combination (bonytongue genera have shifted: the arowanas moved among Scleropages, Osteoglossum and old names like Delsmania, the arapaima has been split into several species, and many mormyrids travel under a former genus). Treat them as a guide to where a species lives, not exact spots: many records are georeferenced to a locality centroid (a nearby village or river mouth) rather than the precise catch site, some are historical or low-precision, and the occasional point may be a misidentification, an aquaculture or ornamental-farm record, or a feral occurrence well outside the native range — the farmed arowanas and arapaima are widely traded, so we keep only points that fall inside the native-range boxes. Many little-collected African mormyrids have no public records yet — an empty map is honest, not an error. No coordinates are invented.
