Narrow-Mouthed Frogs of the United States
The North American specie slack teeth, and have a fold of skin across the back of the narrow, pointed head. The body is plump and the skin smooth and moist. The legs are short and the hind feet have enlarged tubercles used in digging. They are secretive creatures active only at night, they feed almost exclusively on ants.
males give a bleating call to attract females to the breeding ponds, In addition to being clasped firmly behind the forelegs by the male, the female narrow-mouthed's sticky skin secretion also holds the breeding pair otgether. Eggs are laid in a thin, floating film and hatch in a few days. Tadpoles metamorphose in about 30 days.
