Mexipyrgus carranzae

Mexipyrgus carranzae is a species of very small freshwater snail, an aquatic gastropod mollusk in the family Cochliopidae.
Distribution.
This species is endemic to Cuatro Ciénegas valley, in Chihuahuan Desert, Mexico.
Ecology.
"Mexipyrgus carranzae" is generally found only in soft sediment.
Water lily "Nymphaea ampla" is the most common aquatic macrophyte in abundance in its habitats. According to the isotope analysis by Chaves-Campos et al. (2012) it is probable that "Mexipyrgus churinceanus" feed on water lily "Nymphaea ampla" organic matter metabolized by sediment bacteria.
Predators of "Mexithauma quadripaludium" include the specialized snail-eating (molluscivorous) cichlid fish "Herichthys minckleyi".
