保育: Cyprinodon alvarezi 由国际自然保护联盟(IUCN)在濒危物种红色名录中为自然保育而进行了评估 evaluated (EW) 野外灭绝(Extinct in the wild) (2018). Reported extinct in 1994 by Burkhead (2012). I nevertheless was able to see what apparently were the last specimens in March 1996, when the sprigs had been reduced to a few isolated small poodles.
