Blue Poison Arrow Frogs (or blue poison dart frogs) are part of the Poison Arrow Frog family. Its scientific name is Dendrobates Azureas. This amphibian is commonly known as Blue Poison Arrow Frog. It is unique to the Sipaliwini District that is in the southern rainforest of Surinam. This frog usually stays on the forest floor where it is dark and moist. It may also hang about rocks that are close to bodies of water such as streams or ponds.
Their appearance is blue in colour with patches of black on their heads. The hue of it’s blue shade may vary from powder blue, sapphire blue or cobalt blue. The skin of this frog contains neurotoxins which are very deadly. This is one of the larger species of the Poison Arrow frogs. The size is of about 3 to about 4.5 cm in it’s length. The females are a bit bigger compared to the males. The male frogs have larger toe cups and also have vocal sacs in their necks. The males also make a rapid sound similar to drumming. They also have an obvious hunch back. Distinguishing their gender is easy and can be known even in the juvenile age. Blue dart frogs live to an approximate of four to six years when they are in their natural habitat.
The Blue Poison Arrow frogs have a diurnal circadian cycle which means that they are awake during the day. They are very aggressive and outgoing. These frogs have the tendency to be territorial, specially the females. Female frogs may brawl over best place to lay eggs or may fight over male frogs. They may engage in wrestling and even pinning. These frog fights may go to the extent of one frog sitting on another. However, mating pairs do not usually go into fights.
The diet of the Blue Arrow Frog includes fruit flies, ants, crickets and termites. These insects from the rainforests are the source of the alkaloid chemical. These in turn are synthesized into a form of poison. This poison is secreted through the skin. It is utilized as defensive and adaptive mechanisms.
In terms of mating, the female frog is the one to start. Courtship may involve wrestling and chasing. After this, the female lays eggs. Then the male would in turn fertilize them.
The tadpoles hatch from their eggs after 12 days. The young frogs have the tendency to eat their siblings. To avoid this, parent frogs would likely keep them separately. Female frogs would make visits to lay eggs that are unfertilized. This would serve as the tadpole food. The Blue Poison Arrow tadpole would metamorphose into an adult frog after about 12 weeks. The Blue Poison Arrow frogs can be kept as pets. They are non-poisonous when reared in captivity since their diet no longer has it’s original blend of poison inducing rainforest insects.
