Coastal Plain toads are found from extreme southwestern Mississippi to the west Texas. There are a couple of isolated populations in southeastern Mississippi, northeastern Louisiana, southeastern Arkansas and the Big Bend region of west Texas.

This species has broad range of habitat from coastal plains, forests, shrub lands and grasslands. Coastal Plain toads are very common in urban areas such as Austin and Houston, Texas. Often found in city parks, lawns and other green areas.

Diets include arthropods and small vertebrates.

Like most toads, Breeding season starts at the first warm rains during spring but can last until early fall. Like most species of North American toads, Coastal Plain toads lay their eggs in long strings. Eggs are laid in ponds, slow moving creeks and drainage ditches. Young Coastal Plains toads look quite a bit different from adults.

It is quite common knowledge that toads absorb water through their skin. There is a "seat patch" that is specialized for absorbing water. The patch is located in the pelvic region.

In the last several years, this species have had its taxonomical name changed several times. It started as the common name Gulf Coast Toad (Bufo valliceps). The latin name was changed to Coastal Plain Toad (Bufo nebulifer) in 2000. This was because it was determined that B. valliceps was actually two species. B. nebuilifer is found from the northern Mexican coast to southern United States. In 2006, the genus was changed from Bufo to Cranopsis. This was because Bufo was determined to be only valid for eastern hemisphere toads. In 2006, it was changed to Ollotis nebulifer. Three years later Ollotis was replaced by Incilius. So it now sits as the Coastal Plains Toad (Incilius nebulifer).
