The Eastern Narrowed Mouth Toad is found naturally in the southeastern United States but have been introduced to some Caribbean Islands. They are a fossorial species, often hiding in burrows of other species or under logs and leaf litter. The toads come out during the night to hunt for food items such as ants, termites, or small beetles.

Males can be distinguished from females because their throats are dark and highly pigmented while the female’s throat doesn’t have this coloring. Breeding happens between March and October, depending on location. The male frogs start calling starts after a heavy rain fall event.

Interesting fact, the tadpoles of the toad are filter feeders of plankton.
