A Field Study of the Kansas Ant-Eating Frog Gastrophryne olivacea

This scientific study by Henry S. Fitch focuses on the ecology behavior and life history of the Kansas ant-eating frog (Gastrophryne olivacea) also known as the Great Plains narrow-mouthed toad. This species is unique in its diet and habitat being a specialist in consuming ants which gives it an ecological niche within its environment. Fitch’s field study is based on extensive observations of Gastrophryne olivacea in its natural habitat particularly in Kansas. The study begins with a description of the frog’s physical characteristics including its small squat body and narrow mouth which is specialized for feeding on small prey primarily ants. The frog is also well adapted to its terrestrial lifestyle often found in areas with loose sandy soils where it can burrow or hide under rocks and logs.
