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 elusive, typically found during or after rainfall in semi-arid and dry habitats. 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.
