Once contained numerous species, now includes only 5 large to medium-sized poison dart frogs

These diurnal frogs are often brilliantly colored solid red, yellow, or orange or patterned with bold stripes or crossbars. These bright patterns are believed to be warning colors to ward off predators. There are five species in this genus, and all of them are designated as Least Concern by the IUCN.

They breed throughout the year, as long as there is sufficient rainfall, and are known to engage in elaborate courtship rituals. Since poison dart frogs are toxic, they have few natural predators in the wild. The primary threat to their population is increasing human activity in the area of their habitats.
