Rhamdia zongolicensis (common name: Zongolica catfish) is a species of three-barbeled catfish endemic to Mexico.[2][3][4] Its specific name refers to Zongolica, the area in Veracruz state where it occurs. It is a cave fish similar to Rhamdia laticauda and Rhamdia reddelli,[4] and at times considered a junior synonym of the former.[3][4]
Habitat
Rhamdia zongolicensis is only known to occur in a single cave, Cueva del Túnel (Cueva del Ostoc), where it lives in stagnant pools.[5]
Description
Rhamdia zongolicensis grows to at least about 15 cm (5.9 in) standard length. It is related to the surface-dwelling Rhamdia laticauda, considered to be its sister species. Because the surface species is nocturnal, and thereby adapted to darkness, the cave species shows only few new adaptations: elongated barbels and extreme ability to withstand starvation (at least seven months under experimental conditions). It also shows reduced pigmentation and smaller eyes.[5]
Rhamdia zongolicensis is morphologically indistinguishable from Rhamdia reddelli. This is interpreted as resulting from convergent evolution.[5]
