Poison dart frog
Poison dart frogs are a group of small, brightly coloured frogs in the family Dendrobatidae, native to tropical forests of Central and South America.
Poison dart frogs are a group of small, brightly coloured frogs in the family Dendrobatidae, native to tropical forests of Central and South America. They are known for toxic skin secretions, daytime activity, and warning coloration that deters predators. The toxins of some species have been used by Indigenous peoples to tip hunting darts and arrows.
Classification and appearance
Poison dart frogs are amphibians in the family Dendrobatidae. They are typically small and are often noted for vivid colour patterns that function as warning signals to predators.
Habitat and range
These frogs are native to warm, wet tropical forests of Central and South America. They are usually found on the forest floor, though some species live in trees.
Toxicity and diet
Their skin contains toxins that can deter or harm predators. Sources indicate that their toxicity is related to their natural diet in the wild, especially small invertebrates such as ants and termites.
Behaviour and life cycle
Poison dart frogs are generally diurnal and terrestrial, though some are arboreal. Reported wild lifespans range from about 3 to 15 years.
Human use and conservation
Some Indigenous peoples historically used toxins from certain species to coat blowgun darts or arrow tips. Several sources note that many species are threatened or endangered, reflecting habitat loss and other pressures.
Key facts
- Poison dart frogs are members of the frog family Dendrobatidae.
- They live mainly in tropical rainforests across Central and South America.
- Their bright colours warn predators that they are toxic.
- Many species are active during the day, unlike many other frogs.
- Their toxicity is linked to diet in the wild, especially small arthropods such as ants and termites.
Poison dart frogs are commonly featured in Canadian zoo, aquarium, and educational programming, making them familiar to Canadian readers as an example of aposematic coloration, amphibian biodiversity, and rainforest conservation.
