Melanobrynes montevidensis is a small toad about 2–3 centimeters long. Its back is dark or black, and its belly is bright red with black spots, warning predators of the poisonous substances in its skin.
This species is distinguished by its bright red belly, which serves as a warning about poison. The toad is important for nature because it eats many insects and indicates the health of South American wet meadows.
Immature form that undergoes metamorphosis before adulthood.
