Xerocrassa simulata is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae.

Like other land snails, it undergoes a life cycle that includes egg laying, hatching of juveniles, shell development, and reproductive maturity as adults.

These snails play a crucial role in their ecosystem by recycling nutrients and serving as prey for various predators, highlighting their ecological significance in their native habitat.

[4] Xerocrassa simulata (XS) exhibits a dietary preference for plant litter, distinguishing it from other desert snail species that primarily consume biological soil crust (biocrusts).

Despite its dietary preference, XS mucus significantly affects biocrust activity through its deposition.
