Fish[]

Several species of fish are only known from the Ameca River basin: the butterfly splitfin, Tequila splitfin, , , golden skiffia, Amatlan chub, Ameca chub and Ameca shiner. All these are highly threatened.[1][2] The Tequila splitfin, finescale splitfin and golden skiffia are likely extinct in the wild; all three survive in captivity.[3][4][5] The butterfly splitfin and banded allotoca were also thought to be extinct in the wild, but have since been rediscovered.[6][7] The Ameca shiner was once feared entirely extinct, but it too survives in captivity.[3][8] A reintroduction project for the shiner and Tequila splitfin was initiated in 2015.[3]
