The head has round dark-brown spots that are small anteriorly (about the same size as eye) and enlarged and bolder posteriorly (starting at insertion of gills). The head lacks a dark stripe from the nostril through the eye. The enlarged, bold, dark brown spots continue along the dorsum and sides of body to the tip of the tail. The ground colour of the venter is uniform tan, lacking the white punctations along the mid-venter but with such punctations gradually appearing ventrolaterally.

In dorsal aspect, the modal adult lacks snout spotting (73% of specimens), has large dorsal (66% of specimens) and lateral (74% of specimens) spotting, and lacks chin (61% of specimens) and ventral (45% of specimens) spotting. The Pearl lineage diverges from this modal pattern in having a high percentage of snout (63%), chin (54%) and ventral (56%) spotting, and the Mobile lineage diverges from the mode in having a high percentage of small dorsal (54%) spotting and no chin (93%) or ventral (84%) spotting. The modal value for costal grooves is 17 (n = 147), with 35% of specimens possessing 16 grooves, and 2% possessing 18.

. They examined the species in Gilley and Hill Creeks of Smith County, TX where minnow traps placed along stream banks were used to capture waterdogs. The lineage was detected more frequently during November through January; none was detected during May, June, July, and August. This pattern was associated with a negative relationship between captures and water temperature, with no captures occurring when water temperatures exceeded 18°C. Reduction of activity at this temperature is similar to that reported for

Males retained in aquaria showed behaviours consistent with defence of underwater refugia during January and February, the presumed breeding period for free-ranging individuals. Animals captured in the field were associated with sandy- or gravel-bottom regions, typically with logjams.
