The eastern narrowmouth toad (Gastrophryne carolinensis) is native to the United States, from southern Maryland to southeastern Kansas, south to Florida Keys and eastern Texas. It has been introduced to the Little and Great Bahama banks, and on Grand Cayman Island, Cayman Islands, where it is very abundant. It is known to predate on small beetles, ants and termites.
Habitat Description
The eastern narrowmouth toad occupies a variety of shaded moist habitats. When inactive it burrows into soil or hides under debris. It has a tolerance of a degree of habitat modification and can persist in human modified habitats. Males call from beneath objects or buried in grass at water body edges. Eggs and larvae develop in both permanent and temporary water bodies like ponds, rain puddles, swamps ditches etc. (Hammerson & Hedges 2004)
