Endangered
Goodeidae
Allotoca dugesii
Goodeidae is a family of teleost fish endemic to Mexico and some areas of the United States.
Appearance
The family is named after ichthyologist George Brown Goode (1851–1896).
Range and habitat
The Goodeinae are endemic to shallow freshwater habitats in Mexico, particularly along the Mesa Central area (especially the Lerma River basin, smaller rivers directly south of it and inland to around the Valley of Mexico region), with some species found in brackish fringes at the Pacific coast, and north to central Durango, central Sinaloa and north San Luis Potosí. The Empetrichthyinae are found in the southwestern Great Basin in Nevada, the United States, and contains 4 species in 2 genera. Goodeidae is a family of teleost fish endemic to Mexico and some areas of the United States.
GBIF currently lists 168 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Small desert or forest fishes in this order live in water that can vanish. The egg bank, if there is one, is the only reserve.
In crisis
In recent years, there has been a significant reduction in the range and size of Goodeid populations in this region, mainly due to anthropogenic disturbances, such as pollution, eutrophication, habitat modification and desiccation. Recent estimates put habitat loss at 80% compared to historic ranges. Several species are threatened or extinct according to the IUCN and the U.S. Fish and Wildlife Service Vulnerable – bold characodon, darkedged splitfin, Goodea gracilis, Goodeidae Endangered – bluetail splitfin, rainbow characodon, relict splitfin, Allotoca diazi, Manse Spring killifish Critically endangered – blackspot allotoca, Chapultepec splitfin, highland splitfin, Balsas splitfin, Tequila splitfin, butterfly splitfin.
