T. coronata is a small, slender snake, greyish-brown or solid light brown in color.

[4][5] The largest populations of the species is found in areas with sandy or loose soils and plentiful organic litter.

[3] The snake is active during the day during the warmer months of the year, and can be found underneath rocks, logs and organic litter.

It is considered a skilled burrower in sandy soil, and appears to "swim" in the sand when attempting to escape capture.

[3] The snake feeds on several kinds of small prey, including termites, worms, centipedes, earth-dwelling insect larvae, and spiders.

The snake will attempt to burrow in the sand when threatened, or by crawling beneath organic litter and other debris.
