Critically Endangered (IUCN 3.1)

Common name

Atlantic Robber Frog



Species description based on Savage (2002). A moderate to large-sized frog. The head is rather narrow, with a long, pointed snout. Females grow much larger than males (males to 55 mm, females to 80 mm).


Dorsal surface dark brown; sometimes a thin, light middorsal stripe is present.


The ventral surface has dark mottling on a white background. Some yellow or reddish coloration may be present near the rear end, as well as on the undersides of the thighs. A light stripe is always present on the throat.

Concealed surfaces

The groin and posterior surface of the thighs have bright yellow spots or lines on a brown background.


Iris coppery gold with a dark brown line separating the upper and lower halves.


Feet have moderate webbing.

Life history

Breeding season

In Costa Rica, breeding takes place during the initial heavy rains of the wet season (Savage 2002). Males call near the banks of streams (Savage 2002).


Eggs are deposited terrestrially and undergo direct development (Savage 2002).

Ecology behavior and evolution


A deep glug, repeated several times (Savage 2002).


2N = 22 (DeWeese 1976)
