The Spotted Poison Frog is an arboreal poison dart frog, primarily living at least 6 feet (2 meters) off the ground. Juvenile frogs on the species can be found in the leaf litter.

The frogs mate in tree holes that are partially filled with water. If more than one egg is laid, male waits for the eggs to hatch and then carries each tadpole to its own tree cavity. Then, the male guides the female to each cavity where she lays unfertilized eggs for the tadpole to each.

The International Union for the Conservation of Nature (IUCN) Red List assesses the Spotted Poison Frog as Least Concern for Extinction. The frog has a wide range and a presumed large population.

The species is named after Paulo Vanzolini, a Brazilian herpetologist and music composer, specially sambas.
