While hiking through Costa Rica’s rainforests, you might spot a small frog with bright red skin and black polka dots: the strawberry poison dart frog. Its bold appearance and tiny size make it stand out, but there’s more to this creature than its looks. In this guide, we’ll cover everything you need to know about the strawberry poison dart frog, from its toxic skin to where you can find it in Costa Rica.
What Is a Strawberry Poison Dart Frog?
The strawberry poison dart frog, known scientifically as Oophaga pumilio, is a member of the poison dart frog family. Its red skin, often marked with black spots, signals its toxicity to predators. These frogs live in Costa Rica’s lowland forests and can also be seen in private reserves or zoos worldwide.
Their small size and striking colors have made them a favorite among wildlife enthusiasts, but their toxic nature adds a layer of intrigue. Studying these frogs helps scientists understand how animals adapt to their environments through chemical defenses.
Appearance: A Range of Colors
The typical strawberry poison dart frog has a red body with black spots, but its look varies. One common variant, the “blue jeans morph,” pairs a red body with blue or purple legs. Other frogs in this species may show yellow, green, orange, white, or black hues. Measuring 0.75 to 1.5 inches, their small bodies have four un-webbed toes on each foot, suited for moving through the forest.
These color variations, or morphs, often depend on their specific location, with Costa Rican populations showing some of the most diverse patterns. Observing these differences in the wild can feel like uncovering a hidden palette of nature’s creativity.
Where to See Them in Costa Rica
Costa Rica’s warm, humid forests provide the perfect home for strawberry poison dart frogs, and several regions offer prime viewing opportunities. Knowing where to look can turn a casual hike into a memorable wildlife encounter. These frogs are found in lowland forests, particularly in:
- Puerto Viejo de Talamanca: A key spot on the Caribbean coast for wildlife viewing.
- Puerto Viejo de Sarapiquí: A forested area where these frogs are often seen.
- Tortuguero National Park: A biodiversity-rich park where guides can help locate them.
For the best chance to spot them, join a guided tour, as their small size and camouflage make them hard to find without assistance. Many tour operators in these areas offer early morning or late afternoon excursions, when the frogs are most active, increasing your odds of a sighting.

These facts highlight why the strawberry poison dart frog is a fascinating subject for both casual visitors and researchers studying amphibian ecology.
Why the Name “Poison Dart Frog”?
The “strawberry” in its name comes from its red coloring, while “poison dart frog” refers to how indigenous groups used its toxic skin secretions to tip blow darts for hunting. Though toxic to predators, the frog’s secretions are unlikely to harm humans beyond mild skin irritation if handled. It’s best to observe them without touching. This historical use of their toxins connects the frog to cultural practices in Central America, where communities relied on natural resources for survival. Today, the name sparks curiosity among travelers eager to learn about Costa Rica’s wildlife and its human history.
Daily Life: Behavior and Feeding
Unlike many frogs, which are active at night, strawberry poison dart frogs move around during the day, making them easier to spot on guided hikes. Their sharp vision helps them find small prey like ants, mites, flies, and insect eggs. They especially rely on formicine ants, which provide the chemicals for their toxic skin. In the wild, they may eat up to 14 times an hour, while in captivity, they consume 50–75 fruit flies daily.
These frogs are territorial. Males use calls and a toe-tapping motion to communicate, signaling to mates, defending their space, or showing stress. This behavior peaks during the rainy season (May–November), when breeding occurs. Their active daytime habits and frequent feeding make them a dynamic part of the forest ecosystem, constantly interacting with their surroundings.
Reproduction: A Careful Process
Strawberry poison dart frogs reproduce differently from other frogs. Females lay 2–12 eggs on leaves or near water, far fewer than the hundreds laid by other species. After hatching, the female carries each tadpole to a small water pool, often in plants like bromeliads, and feeds them unfertilized eggs until they mature.
This hands-on parenting is unusual for frogs and adds to their uniqueness. The breeding season, tied to Costa Rica’s rainy months, ensures water sources are available for tadpole development. This careful reproductive strategy reflects the frog’s adaptation to its environment, where resources can be scarce, and survival depends on precision.
Are They a Threat?
Their toxic skin deters most predators, with the fire-bellied snake (Leimadophis epinephelus) being their only known natural enemy, resistant to the toxins. For humans, the frogs aren’t dangerous but can cause irritation if touched.
The greater threat to them is habitat loss from deforestation and climate shifts. This balance of being both predator-proof and vulnerable highlights their complex role in the ecosystem. Travelers should appreciate their resilience while recognizing the importance of preserving their forest homes.
Conservation: Stable but at Risk
The strawberry poison dart frog is listed as “Least Concern” by the IUCN due to its stable population. However, deforestation and habitat changes in Costa Rica pose challenges. Protected areas like Tortuguero National Park and private reserves help safeguard their future.
Conservation efforts also involve local communities and ecotourism, which raise awareness and funds for habitat preservation. By visiting responsibly, travelers can support these initiatives and ensure future generations can enjoy these frogs in the wild.
