Dendrobates Leucomelas

Yellow Banded Poison Dart Frog

Dendrobates Leucomelas is both dangerous and alluring, and simply touching this charming frog is enough to disrupt nervous impulses, which can eventually lead to heart failure.

But do not fear, as this yellow-banded poison dart frog, as it is commonly called, loses much of its toxicity in captivity where it is kept from its toxin-compound laden food diet. As a pet, it is one of the easiest poison frogs for budding herpetologists to maintain. Here are some features and interesting information about this yellow hopping creature.

Habitat and Adaptation

Dendrobates Leucomelas are aggressive, territorial, solitary amphibians that love humid conditions, and exist naturally in the tropical rain forests of Venezuela, Guyana, and Colombia, in South America. They live in the leaf litter on land, flat rocks or at times on trees, wherever they can find a damp place. In comparison to other poisonous frogs, the yellow-headed ones are bold and adaptable, with the ability to withstand considerable variations in humidity and temperature. They can even adapt to living in dry forest environments and at high altitudes.

The largest among species of Dendrobates frogs, Dendrobates Leucomelas extend up to 5 cm in length, and weigh around 3g, with the females being slightly larger than the males. The yellow skin is marked by broad black strips, which in combination with the poisonous skin, serves as a warning signal for predators who attempt to make this frog their meal. The frogs themselves are insectivorous and also feed on non-insect arthropods. They catch their prey with their short and sticky tongues, firming their grip with the help of glandular adhesive pads on the toes. With age, the black bands on its skin break and transform into spots.

Reproduction and Care

The sex of Dendrobates Leucomelas can be distinguished by the calling behavior, as the male makes peculiar sounds from his hiding position, seeking a female partner. The male frog finds a suitable mating site for the female to lay the eggs, and then protects and provides moisture to the eggs. He later transports the hatched tadpoles to a water source or water-holding plant, like bromeliads. After a period of about three months, the tadpoles metamorphose into froglets, which eventually mature at about two years of age.

A single Yellow-banded adult poison frog would require at least a 35-liter vivarium, but it is best to keep them in pairs or groups not exceeding five in a larger vivarium. Temperatures should be maintained between 20 degrees Celsius and 26 degrees Celsius with a minimum humidity of 90%.

Dendrobates Leucomelas, whose lifespan is up to 7 years in the wild, can survive to about 15 years in captivity. They are a delight to see and help in conservation of their eco-system.
