Xiphophorus meyeri Schartl & Schröder, 1988

Marbled swordtail

 

 

Taxonomy & Nomenclature

 

 

Conservation Status

Extinct in the wild

Last wild record: 1997

IUCN RedList status: Extinct in the Wild

 

"The Marbled Swordtail is historically endemic and restricted to the springs of La Cascada and El Socavon, as well as the small creeks which connect these freshwater springs located in Melchor Muzquiz, Coahihula, Mexico. Due to complete loss of habitat through water abstraction for mining activities, the species is considered extinct in the wild. The last sighting of this species was in 1997 and it has since been extensively sampled. Its habitat has now been recovered and a major priority for conservation of this species is reintroduction of ex-situ individuals back into its natural habitat. Development of an ex-situ breeding program and expansion of ex-situ holding sites is necessary to secure the future of the species. This species is listed as Extinct in the Wild."
