Physical Description
Adults are 2 3/5 - 3 inches, (64.5 - 75.0 mm) in length (Wright 1949). They have a toad-shaped body with a large head and small truncated toe pads. They are greenish to tan, smooth skinned, with scattered dark spots. They also have dorsolateral skin folds on the back and one fold across the back of the head. They possess a disk-shaped fold on their belly (Behler 1979). The young are often greenish with a fawn-colored band across the middle of their back (Conant 1998).
Reproduction
Breeding is from February to May, during rainy periods.They lay their eggs under rocks and logs in moist soils.The tadpole stages occur within the eggs and they hatch as fully developed miniature frogs (Behler 1979).
Behavior
Their call at a distance sounds like a dog's bark, but close up sounds more like a throaty whurr (Wright 1949). They are nocturnal. They walk with their body high off the ground. They can inflate to several times their normal body size when threatened (Behler 1979).
