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.
