Description

Green toads are typically bright to pale green in color, with black spotting. They are not large toads; adult males are about in snout–vent length and females .


Habitat and reproduction

Green toads are relatively widespread and at least locally common. They are secretive, however, only readily found during and immediately after periods of rainfall; their habitat is semi-arid and often very dry. Breeding occurs from late March to August, stimulated by summer rains. Males move from drier, terrestrial habitat to aquatic breeding sites where they form choruses. Females are attracted by chorusing males. Breeding aggregations do not usually last long, only a few days.
