The Pacific Lowland Poison Frog lives in a variety of habitats in western Ecuador including the dry scrublands, deciduous forests, and the Choco rain forests. The female frog lays her eggs on land. After the female frog lays around 15 eggs, she leaves and the male takes care of the eggs. The male protects the eggs from predators and carries them on his back. Once the eggs hatch into tadpoles, the male carries them to a stream bank or pond where they will continue to grow and finish their metamorphosis.

The International Union for the Conservation of Nature (IUCN) Red List assesses the frog as Least Concern for Extinction. They have a wide range and believed to be large population. While listed as Least Concern, there are threats to the frogs from humans (we the worst).Areas of forests where the frog calls home are being logged and turned into farms.
