Blue Poison Dart Frog

Taxonomically named Dendrobates azureus, it is a type of poison dart frog found in the forests surrounded by the Sipaliwini savannah, which is located in southern Suriname and northern to central Brazil. Dendrobates azureus is widely known as the Blue Poison Dart Frog or by its Tirio Indian name, Okopipi. It takes its species name from the fact that it is colored azure.
D. azureus is a medium-sized frog that weighs approximately 8 grams. It grows between 3 and 4.5 cm in length and has a typical lifespan of 4–6 years in the wild. Its bright blue skin serves as a warning to predators. Its colour is also usually darker around its limbs and stomach. The glands of poisonous alkaloids located in the skin serve as a defense mechanism to potential predators. These poisons paralyze and sometimes kill the predator. The black spots are unique to each frog, serving as an identification tool. Each foot contains four toes which each have a flattened tip with a suction cup pad which is used for gripping. This species of frog is also identifiable by a hunch-backed posture.
Dendrobates azureus is a mainland animal, but stays close to water sources. These frogs spend most of their awake time during the day, hopping around in short leaps. They are very territorial and aggressive both towards their own species and others. In order to ward off intruders, they use a series of calls, chases, and wrestling, which usually occurs within the same sex.
Although poison dart frogs are known for their skin toxin, used on the tips of arrows or darts of natives, in reality only the species of the Phyllobates genus are used in this manner, although all poison dart frogs have some level of toxicity. In captivity, the frog loses its toxicity as a result of an altered diet.
The Blue Poison Dart Frog breeds seasonally, usually during the months of February or March when it is rainy. In order to find a mate, the males sit on a rock and produce quiet calls, which the female follows and tracks down the male. The females then physically fight over the male. The male takes the female to a quiet place by water to mate, which becomes the site of the egg-laying.
Between five to ten offspring are produced, and eggs are laid in the male’s territory, which he defends. The male takes care of the eggs most of the time, but sometimes the female does as well. The eggs hatch between fourteen and eighteen days, and after anywhere from ten to twelve weeks, the tadpoles are fully mature. Both sexes reach sexual maturity at two years of age. The expected lifespan of an average D. azureus is between four and six years in the wild, and about ten years in captivity. |
