Their skin color is mostly light brown with some darker spots on the back,[3] so they can easily avoid predators. The head of the Pipa Pipa has a very flat appearance and is triangular. It also has very small black eyes, that are located on the top of their head. These are not the only different characteristics, the toads have very long fingers that end in four star-shaped lobes. The Surinam toad has no teeth and no tongue.
