Their hind legs are long with webbed hind feet. There are still gaps in our knowledge of golden mantellas' habits. The vivid color of these frogs strongly contrasts with the dull surroundings of the forest. It is believed that this color is a visual signal warning predators that the skin contains toxins that could make them ill. It is thought that golden mantellas fertilize their eggs internally, as well as externally.
Most frogs only fertilize their eggs outside of the body.
They will lay 25-50 relatively large eggs in moist areas, and only lay the eggs at night. The males will guard the egg mass until the tiny tadpoles hatch. The tadpoles then live in water until metamorphosis is complete. In the wild matellas eat insects. The zoo keepers feed our mantellas brown crickets and fruit flies.
