The Sumaco Horned Treefrog is a nocturnal and arboreal frog species. They live their lives in the trees above the forest.  After mating, the females of the species carries their eggs on their back until they hatch into froglets, skipping the tadpole phase.  They can carry up to 26 eggs on their back at one time! They carry the eggs to help protect them from predators. The Sumaco Horned Treefrog has large fangs on their bottom jaw that is used to grab onto prey like lizards and other frogs. For protection, they can open their mouth to reveal their bright yellow tongue, which can scare off predators.
