Adult males court females from a distance by producing advertisement calls. Additionally, they engage in throat display and toe tip jumping. As they vocalize, their skin color changes from pale brown to jet black. When a nearby female receives a male's call signal or notices its skin coloration, the

Adult males then guard and tend to the eggs until they hatch after about 21 days. When predation risk is high, males will transport their tadpoles on their backs for long distances between 3 and 4 days and selectively deposit them into predator free pools. Such tadpole transportation does not incur

Trinidad poison frogs engage in two types of territorial defense. The first involves nonreproductive regions where frogs will defend resource access to food, water, and shelter. The second involves large reproductive regions where frogs will defend against conspecific calling rivals during the

Concern" on IUCN, but there is a general lack of understanding of its distribution. The frog experiences habitat loss. Both sexes are territorial and provide parental care together.

Adult female
Trinidad poison frogs display territorial defense against other frogs through aggressive behaviors such as visual threat displays, wrestling, and chasing. During threat displays, females will reveal their bright yellow throats against intruders.

Adult
Trinidad poison frogs are a relatively small and diurnal species. Their dorsal surface is brown and dark and their flanks are mottled. The Trinidad poison frog is sexually dimorphic. Adult males have grey throats and average 25 mm in

Adult males, in contrast, defend their territories against both predators and other male intruders by producing advertisement calls at their calling sites. Such defense is intended to deter competitors and attract females as potential mates.
