Often unpigmented or appear speckled white on the tail end. A thin line of color down the center of the body comes from the recent food they have eaten.

These small isopods range between three to 4 millimeters in length with a long, slender, colorless body.

The Texas troglobitic water slater is an eyeless, unpigmented groundwater crustacean living within the Edwards Balcones Fault Zone Aquifer where no light present. In this dark habitat, they walk along the interstitial karst limestone spaces and can get caught in conduits of flow up through artesian wells and springs where they can be captured by researchers. This species diet is comprised mostly of food produced by chemolithoautotropic bacteria using chemicals, -chemo, from the limestone rock, -litho, creating energy made internally, -auto, that serve as food resources, -troph.  A petition was issued to list this species and the Service published a 90-day finding in 2009 stating this water slater may be warranted for listing based on presented substantial scientific or commercial information.

This species of water slater feeds on organic matter that is created by chemolithoautotrophic bacteria and is produced underground, in the absence of light or nutrients created by photosynthesis, at the freshwater/saline-water zone on the southeastern border of the Edwards Balcones Fault Zone Aquifer. Simply put, these microbes use minerals as fuel. To produce organic matter, they use chemicals, or chemo, from the limestone rock, or litho, to create energy that they make internally, or auto, that serve as a food resource, or troph.
