Introduction
Strawberry Poison Dart Frogs (Oophaga pumilio) are a small, brightly colored species of amphibians native to Central America. These frogs are famous for their striking red, blue, and black coloration and their toxic skin secretions, which they use as a defense against predators. In this post, we will discuss the breeding behavior and parental care of this fascinating species, including their unique strategy of carrying tadpoles to bromeliads.
From the family Dendrobatidae, this Strawberry Poison Dart Frog (Oophaga pumilio) is also known as the blue jeans frog.
Reproduction and Parental Care
Strawberry Poison Dart Frogs are known for their exceptional parental care. Males are responsible for finding a suitable breeding site and they call females to lay their eggs. The female lays three to five eggs on a leaf or bromeliad axil. The males ensure the eggs are kept hydrated. After about 10 days, the eggs hatch and the female transports the tadpoles on her back to some water-filled location.
Once the eggs hatch, the male frog carries the tadpoles on his back to a nearby bromeliad plant. Bromeliad axils are frequently used tadpole deposition sites, but anything suitable can be used, such as knots in trees, small puddles, or human trash such as aluminum cans. The bromeliad’s leaves collect water, which serves as a perfect breeding site for the tadpoles.
After about a month, the tadpole will metamorphose into a small froglet. Generally, the metamorph stays near its water source for a few days for protection, as it absorbs the rest of its tail.

Tadpole Diet
Strawberry Poison Dart Frog tadpoles are known to have a unique diet. Instead of feeding on algae and other aquatic plants like most tadpoles, they feed on unfertilized eggs laid by the female frog. This adaptation is a result of the limited food resources available in their rainforest habitat. They are considered obligate egg feeders, as they are unable to accept any other form of nutrition.
Geographical Distribution and Conservation Status
Strawberry Poison Dart Frogs are found in Central America, from eastern central Nicaragua through Costa Rica and northwestern Panama. The species is listed as Least Concern by the International Union for Conservation of Nature (IUCN) but there are some threats, such as habitat loss and fragmentation caused by deforestation, agriculture, and urbanization. Additionally, the pet trade is also contributing to the decline of wild populations. Never purchase wild-caught amphibians!
Conclusion
Strawberry Poison Dart Frogs are a unique and fascinating species known for their striking colors and exceptional parental care. Their ability to carry tadpoles to bromeliads and feed them unfertilized eggs is a remarkable adaptation to their habitat. However, their threats are a cause for concern, so it is essential to protect their rainforest habitat and prevent harvesting of their wild populations, in order to ensure the survival of this species.
