Slightly larger than Mud creepers, T. sulcata has a distinctive shell opening known as a peristome.

This smooth, slightly flared opening can be applied onto the substrate by the animal, enabling it to resist evaporation and predators.
This species does not have a pallial (mantle) eye, although there is a shallow, possibly light-sensitive pit on the underside of the inhalant siphon.
