Peltophryne guentheri, the southern crested toad or Gunther's Caribbean toad, is a species of toad in the family Bufonidae. It is endemic to Hispaniola and found in the lowlands of Haiti and the Dominican Republic.[2]
Males grow to 74 mm (2.9 in) and females to 101 mm (4.0 in) in snout–vent length.[3] The dorsum has a yellowish tan ground color and is heavily overlaid with a very dark brown to black reticulated pattern.[4]
Natural habitats of Peltophryne guentheri are dry lowland valleys in both mesic and xeric areas.[1] These frogs have been observed to sit on or near piles of cattle manure. They appear to use a sit-and-wait foraging strategy to catch insects on the manure.[3]
Breeding takes place in temporary pools,[1] including a rainwater-filled roadside ditch.[3] Breeding is triggered by heavy rains, and the breeding season corresponds to the Atlantic hurricane season.[3]
It is threatened by habitat loss caused by livestock grazing and selective logging, and by agricultural pollution.[1] All observations of these animals are from degraded habitats[1][3] where the populations are facing further habitat degradation caused by urban development. A further threat is competition with and predation from introduced cane toads (Rhinella marina) and American bullfrogs (Lithobates catesbeianus). Males have also been observed attempting to mate with a male Rhinella marina.[3]
