Critically Endangered
Quintana atrizona
Quintana atrizona
Quintana atrizona is a poeciliid fish endemic to Cuba.
Appearance
In females, the dorsal fin sits roughly opposite the anal fin. In males it is slightly farther back. The dorsal fin is triangular and neatly marked, while the tail fin is gently rounded. Males carry a gonopodium, a specialized anal fin used for reproduction, while the female anal fin is simply pointed.
Females grow to about 5 cm, males to 3 cm.
Range and habitat
Quintana atrizona is endemic to Cuba, where it is found at elevations of 1 to 5 metres (3.3 to 16.4 ft) above sea level. It is native to small freshwater ponds in western Cuba and Isla de la Juventud and has also been found in a small freshwater lagoon at Guanahacabibes Peninsula and the Itabo river. Since the 1970s, dam construction has caused extensive habitat fragmentation and destruction.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Livebearers drop free-swimming young. Many species occupy springs, lakes, or ditches with little room to retreat.
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
Its preferred habitats, heavily vegetated still and slow-moving waters, have been destroyed or degraded, and the species is considered critically endangered.
