These little frogs are easily recognized by their blue color, which is generally darker on the limbs and belly and overlaid with black spots or patches, especially on the head and back.
As their name implies, poison dart frogs can release toxins from the skin that are distasteful and potentially lethal to would-be predators.
Blue poison dart frogs are active during the day and can be found hiding among boulders and debris near streams and among leaf litter on the forest floor; however, they lack toe webbing and are poor swimmers, so they are not found in the water.
The blue poison dart frog lays small clutches of five to six eggs. After the eggs hatch, the parents transfer tadpoles to individual pools of water, where they finish development. At the Aquarium, we replicate this by raising tadpoles in small individual containers of water.
Blue frogs are some of the most fascinating amphibians on our planet. Though not commonly seen in nature, these vividly colored creatures have captured the imagination of scientists and frog enthusiasts alike. In this article, we’ll explore the biology, behavior, habitat, and conservation status of these eye-catching amphibians.
What Makes Blue Frogs Unique?
Most frogs come in shades of green, brown, or grey – effective camouflage in their natural environments. Blue frogs, however, sport brightly colored blue, purple, or turquoise skin. This is unusual in the frog world and makes them really stand out.
So what causes this vibrant blue hue? Blue frogs get their color from unique proteins in their skin that reflect blue light. Some species, like the Strawberry Poison Dart Frog, have blue legs but are red or green on top. The bold colors of blue frogs are thought to warn predators that they are toxic.
Blue frogs span several genera and families, with species found in North, Central, and South America, as well as Australia and Europe. Some of the most vibrantly blue species include
- Blue Poison Dart Frog
- White’s Tree Frog
- Strawberry Poison Dart Frog
- Green and Black Poison Dart Frog
Many blue frogs secrete toxins to deter predators The two dendrobatid (poison dart frog) species have some of the most potent toxins While beautiful, it’s best to look but not touch these spectacular amphibians!
Habitats and Behaviors
Blue frogs occupy a variety of habitats across their global range. Many inhabit humid tropical forests, where they blend in nicely against colorful flowers, fruits, and leaves. A few temperate species, like the Moor Frog, live in marshes, ponds, and lakes.
Species like the White’s Tree Frog and Northern Pacific Treefrog perch in low branches and trees bordering water Most dart frogs and their relatives live on the ground among the leaf litter
Blue frogs often have unique reproductive strategies. Male Strawberry Poison Dart frogs court females by making bird-like whistling sounds. Competition is fierce – males wrestle each other for the attention of females. Once mated, the pair finds a quiet, damp place to spawn.
Parental care is common in dart frogs. Males of many species transport freshly laid eggs on their backs to a safe location. After hatching, adult frogs even carry tadpoles to small pools of water trapped in tree holes or leaves.
Conservation Status and Threats
Due to their small ranges and fragile habitats, a number of blue frog species are threatened or endangered. The IUCN lists the Blue Poison Dart Frog as Least Concern, though its status in the wild is not well understood. Other species like the Blue-Legged Mantella and Harlequin Frog are endangered.
Major threats to blue frogs include:
- Habitat loss from deforestation
- Stream sedimentation
- Pollution
- Disease, such as chytridiomycosis
- Collection for the pet trade
Protecting remaining patches of tropical forest and controlling the wildlife trade are crucial for conserving these amazing amphibians. Maintaining Captive breeding programs and crafting species reintroduction plans should also help bring blue frog populations back from the brink.
For all their small size, blue frogs have an outsized presence in the ecosystems they inhabit. Their jewel tones liven up leaf litter and forest floors across the Americas. And while super toxic species should only be admired from a distance, milder species can make fascinating pets for responsible owners.
The rarity and beauty of blue frogs gives them appeal the world over. But it also makes protecting their fragile habitats and populations all the more important. With care and persistence, these glittering amphibians can continue to dazzle us long into the future.

A Note From the Caretaker
Learn more about the blue poison dart frog! Did you know that this colorful frog was not discovered by scientists until 1968?
These frogs are found in a few isolated “rain forest islands” in the Sipaliwini savanna of southern Suriname.
This area was probably covered by rain forest habitat in the distant past—until the last ice age. The rain forests have since given way to dry grassland in all but a few areas where surface groundwater was sufficient to sustain the original vegetation. The blue poison dart frog lives in a few isolated patches of relic rain forest habitat.
A constant forager, this frog is always searching for mites, termites, tiny beetles and any other small insect it may find among leaf litter.
An adult frog has a body about 2 inches long and weighs about 0.3 ounce.
The habitat is remote and difficult to reach, so accurate population monitoring is a challenge. Regardless of numbers, this species is highly vulnerable to both human activities and natural factors, such as drought, due to its extremely small range and isolated populations.
Adult dart frogs have few predators, but the tadpoles, which contain no toxins, often fall prey to other amphibians, reptiles and predatory invertebrates.
The Poisonous Dart Frog – Blue Frog
FAQ
How rare are blue frogs?
Expert says blue frogs represent about 0.003 per cent of commonly found green frogs.
Where are blue frogs found?
In the Wild: The blue poison dart frog is found in a few isolated “rainforest islands” in the Sipaliwini savanna of southern Suriname. These old forests are relatively cool (71.6-80.6 degrees F, cooler at night), and humid with running rocky streams.
How long do blue tree frogs live?
Proper moisture is critical – 10 to 20 gallon enclosures work for most species. Frogs are generally sturdy under proper conditions & long lived (between 4 to 15 years depending on species). In general, frogs are not for handling. We breed several species/color morphs.
What do blue frogs eat?
In the wild, their diet consists of ants, beetles, caterpillars, flies, maggots, mites, spiders and termites. They lose their toxic qualities in captivity because they are raised on fruit flies and crickets. Senses: Blue poison dart frogs have excellent senses of sight and smell.
What is a blue poison dart frog?
The blue poison dart frog is a medium-sized poison dart frog that weighs about 8 g (0.28 oz) and grows to 3.0–4.5 cm (1.2–1.8 in) in snout–vent length. Females are larger and on average about half a centimetre longer than males, but males have larger toes.
What is a blue poison arrow frog?
The blue poison dart frog or blue poison arrow frog (Dendrobates tinctorius “azureus”) is a poison dart frog found in the “forest islands” surrounded by the Sipaliwini Savanna in southern Suriname. Its indigenous Tiriyo name is okopipi. The name “azureus” comes from its azure blue color.
Are blue frogs poisonous?
Blue frogs, often bred in captivity, are known to be highly poisonous. Denver Zoo names Blue Dart Frogs as one of the most poisonous frogs and even one of the most poisonous amphibians in the world.
What is the lifespan of a blue poison dart frog?
A blue poison dart frog typically lives for around 10 to 15 years. These frogs are active mainly during the day and can be found close to water sources. They are also known for being aggressive and territorial.
Are frogs naturally blue?
Blue is one of the rarest colors in nature, but in the world of frogs, blue is actually a fairly common color. Few animal species are naturally blue, and few plants have blue flowers.
What is the scientific name of the blue dart frog?
The blue dart frog’s scientific name is Dendrobates tinctorius “azureus”. Though considered a valid species initially, at present it has been considered a variant of another poison dart frog, i.e. the dyeing dart frog.
