Mexipyrgus carranzae is a species of very small freshwater snail, ^[2] an aquatic gastropod mollusk in the family Cochliopidae. ^{[2] [3]}

Distribution

This species is endemic to Cuatro Ciénegas valley, in Chihuahuan Desert, Mexico. ^[2]

Ecology

Mexipyrgus carranzae is generally found only in soft sediment. ^[4]

Water lily Nymphaea ampla is the most common aquatic macrophyte in abundance in its habitats. ^[4] According to the isotope analysis by Chaves-Campos et al. (2012) ^[4] it is probable that Mexipyrgus churinceanus feed on water lily Nymphaea ampla organic matter metabolized by sediment bacteria. ^[4]

Predators of Mexithauma quadripaludium include the specialized snail-eating (molluscivorous) cichlid fish Herichthys minckleyi . ^[2]
