Description
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
Their tadpoles have a long tail, about 6 mm, with a total length of around 10 mm. They lack legs and have gills instead of lungs.
Behavior
The blue poison dart frog is a terrestrial animal, but, as an amphibian, stays close to water sources. These frogs spend most of their active hours hopping around in short leaps, looking for insects.[citation needed] They are very territorial and aggressive, both towards their own species and others, much like other poison dart frogs. To ward-off intruders, they use a series of calls, chases, and wrestling.
Although poison dart frogs are known for their skin toxins used on the tips of hunting-arrows of natives, in reality, only the species of the genus Phyllobates are used in this manner. In nature, poison dart frogs consume specific insects, such as small beetles or ants, which contain formic acid (among other alkaloids), something the frogs are able to metabolize and retain as a defense mechanism. Thus, all captive and captive-bred dart frog specimens, including wild-collected individuals, lose their toxicity as a result of a change in diet.
Reproduction
The blue poison dart frog breeds seasonally, usually during February or March when the weather is rainy. To find mates, the males sit on a rock and produce quiet calls, which the females follow to track down the males. The females then physically fight over a male. The male takes the female to a quiet place by the water, which becomes the site of the egg-laying. Fertilization occurs externally; once the eggs are laid, the male covers them in his sperm.
Between five and ten offspring are produced at each mating. Eggs are laid in the male's territory, which he defends. The male takes care of the eggs, sometimes joined by the female. The eggs hatch after 14 to 18 days, and after 10 to 12 weeks the tadpoles are fully mature. Both sexes reach sexual maturity at two years of age. The expected lifespan of D. tinctorius "azureus" is between 4 and 6 years in the wild and about 10 years in captivity.
Feeding
The blue poison dart frog feeds on fire ants and insects which may have poisonous chemical which makes the blue poison dart frog poisonous. Other than that it also feeds on beetles, flies, mites, spiders, termites, maggots, and caterpillars.
Captive care
In captivity, like most captive dart frogs, they eat a staple diet of fruit flies, pinhead crickets, rice flour beetle larvae, isopods, and springtails.
