Poison dart frogs are a tiny species of frog that lives in Central and South America.

One of their main adaptations to keep them safe from predators is their brightly colored skin, which ranges from yellow to bright blue or red. This skin warns predators looking to add them to their diet that these tiny frogs are extremely toxic if ingested.

5 Incredible Poison Dart Frog Facts!

• A group of poison dart frogs is known as an “army.”
• One of this frog’s adaptations is its brightly colored body, from blue to red and black to golden yellow.
• Poison dart frogs are sometimes known as “poison arrow frogs.”
• The golden poison dart frog, the most toxic of all of the frog species, has enough toxin in its body to kill over 20,000 mice.
• Some varieties of these frog’s poison show promise in the medical field, including one being synthetically adapted to be a painkiller for humans.

Poison Dart Frog Scientific Name

These frogs belong to a wide array of genus and species, with many different scientific names. There are over 175 known species. However, all belong to the family Dendrobatidae. This scientific name is formed from the Greek word for tree, dendro, which is also used in the word dendrology, the study of trees. Batēs is the Greek word meaning “one that treads.” Therefore, the family name Dendrobatidae means “one that reads in trees,” or simply “tree climber.”

Poison Dart Frog Appearance

One of the adaptations these frogs are famous for is their brightly colored skin. This skin serves as a warning to predators about their extremely toxic secretions. The term for creatures that have bright coloration to warn predators that they are toxic is called “aposematic coloration.”

The different species come in a rainbow of colors, including blue, yellow, red, green, golden, and black. The strawberry poison dart frog is one of the species’ most poisonous members and has a bright red body with blue legs. The golden poison dart frog is also especially dangerous and has enough toxin to kill over 20,000 mice. It is also the largest of the poison dart frog species.

However, the facts are that not all members of the poison dart frog family are poisonous, or brightly colored. Some humble species come in shades of tan and brown, and these species are usually not toxic to most animals.

These frogs tend to be small, with the average length being around 1 inch. Like most frog species, their skin is smooth and damp, and they have webbed toes.

Poison Dart Frog Behavior

Some facts about these frogs’ behavior include that they like to live in the trees closest to the ground, or the leaf litter of the jungle floor. They prefer resting on leaves and tree branches.

These frogs croak and squeak like other frog species, using these calls to establish their habitats and attract mates. They are mostly diurnal creatures, which means they are active during the day.

These frogs make little attempt to hide from predators, as their skin is warning enough. If their toxins don’t kill a predator, they will at least make them very unappetizing. Predators will remember the unpleasant taste of this frog, and will likely not attempt to eat another one again.

Poison Dart Frog Habitat

These frogs are native to the damp rainforests of Central and South America. They can sometimes be confused with another small, brightly colored frog species called the Mantella, but Mantellas are only native to Madagascar.

These frogs have also been introduced to Hawaii. They used to be imported to the US in great numbers for the pet trade, but this has since slowed down. In Europe, some species of frogs are smuggled into the country.

Because of their sensitivity to the environment, these frogs do not do well in heavily polluted areas.

Poison Dart Frog Diet

These frogs use their long, sticky tongue to capture insects. This diet makes the frog a carnivore. Their diet consists of termites, flies, ants, and many other species of insects, which are plentiful in the habitat where poison dart frogs live.

Tadpoles can be omnivorous and sometimes eat algae. They are also sometimes fed unfertilized eggs from their parents. Some species of frogs are even cannibals and eat the tadpoles of other species.

It is thought that the diet of the poison dart frog is responsible for their toxicity. Scientists are unsure which of the insects the frogs eat to make them toxic. However, frogs raised in captivity and fed crickets and fruit flies do not release toxins from their skin.

Poison Dart Frog Predators and Threats

Because the toxins in their skin make them unpleasant or even toxic for most animals to eat, poison dart frogs do not have a wide array of natural predators. There is a species of snake, Leimadophis epinephelus that is immune to the venom of the poison dart frog.

Frog species, including the poison dart frog, sometimes fall victim to the chytrid fungus. This disease is a type of infective fungus that causes lethargy, weight loss, and eventually death. It is highly contagious and threatens over 100 different frog species.

Many species of poison dart frog are listed as endangered or critically endangered due to habitat loss and pollution. Large swathes of rainforest are often burned to make room for farmland as well as deforested for lumber. Some species are also captured and exported for the pet trade.

Poison Dart Frog Reproduction, Babies, and Lifespan

Poison dart frogs breed multiple times throughout the year, often in conjunction with periods of rainfall. Both males and females are combative during this time – males compete for ideal perches from which to call for mates, and females compete for nesting areas. Females are sometimes known to devour the eggs of other frogs.

The mating process occurs once the male has performed his mating call and located a female with which to breed. The male lures the female to a place he would like to mate using an elaborate courtship ceremony. This courtship consists of wrestling, stroking, and leading the female around. The ceremony can last many hours before the two decide to settle, and the female can lay her eggs.

Females will deposit their eggs in the moist leaf litter. The amount of eggs varies from 1 egg to 40 eggs, with the average being about ten eggs per clutch. The male will then fertilize the eggs once the female has lain. Both parents will guard the eggs, taking care to make sure they do not dry out.

Once the young tadpoles hatch, about 10 to 18 days after the eggs have been fertilized, the parents will carry the tadpoles on their backs. When the parent frog sits in the cluster of young tadpoles, they can squirm their way onto the parents’ back. The parents carry their young, either all at once or a few at a time, to small pools where they can grow and mature. Tadpoles will grow into adult frogs after many months. In this young form, they are exceptionally vulnerable to predators.

The lifespan of the poison dart frog is not well-researched. In the wild, some scientists say they live as few as three years. In captivity, it is reported that some species can live to be up to 25 years old.

Poison Dart Frog Population

Poison dart frogs, like many other species native to the rainforests of South America, are in population decline. Some species are endangered or critically endangered due to habitat loss, climate change, and fungal disease. Because of the number of species as well as their remote location, it is not possible to get accurate measurements of population data.

Poison Dart Frog In the Zoo

These frogs are a common attraction in zoos and aquariums everywhere. The San Diego Zoo and the Smithsonian both have captive poison dart frogs, as well as Reid Park Zoo and the Seneca Park Zoo.

In zoos, these frogs are fed insects that do not cause them to develop toxins in their skin. They are fed insects like these because they frequently need to be handled by zookeepers and vets while in captivity.
