Hidden inside the stunning red lily from a Costa Rican rain forest is one of the smallest of all frogs, the diminutive small glass frog, Hylenidae. Small insects visiting the lily for its pollen are easy prey for this well–concealed frog.

The Colorado River toad, Bufo alvorius, is one of the largest species in the United States, and apart from its size, has no distinguishing markings, being mostly brownish gray above and paler on the underside. Its skin produces poisonous secretions that predators find distasteful, so it is normally avoided.
