The green-and-black poison dart frog (Dendrobates auratus), also known as the green-and-black poison arrow frog and green poison frog (among others), [1] [3] is a brightly-colored member of the order Anura native to southern Central America and Colombia. This species has also been introduced to Oahu, Hawaii in an effort to lower mosquito numbers. [1] [3] [4] It is one of the most variably colored species of poison dart frogs, after D. tinctorius , Adelphobates galactonotus and some Oophaga species. From a conservation standpoint, it is considered to be of least concern by the International Union for Conservation of Nature. Within the reptile and amphibian hobby, D. auratus remains one of the most commonly kept, and easiest-to-breed, dart frogs in captivity, as well as in zoos. [1]

Description

Although typically blackish with a variable pattern of green, other colors are also possible. Blue is seen in certain locations in Panama Dendrobates auratus (aka).jpg

The green-and-black poison dart frog has the typical appearance of the members of its family; males average 0.75 in (1.9 cm) in snout–vent length, while females are slightly larger, averaging 1 in (2.5 cm) or longer.

The green-and-black poison dart frog is one of the most variable of all poison frogs in color and pattern. This variation is to some extent individual, but also depend heavily on exact location. Despite the name green-and-black poison dart frog, some variants have no green or no black; a few, like the brown and cream-white Campana variant, may have neither green nor black. However, most often, green-and-black poison dart frogs have a highly variable, spotted or banded pattern in vivid mint-green coloration, but this can also be a darker green, forest-green, lime, emerald, turquoise, or even blue, whitish or pale yellow. Mixed with this are splotches of dark or dull coloring, most often blackish, but ranging from whitish-brown and bronzy brown to dark brown and pure black. The amount of dark or dull coloring varies greatly (certain variants are entirely black, or dark with only a few small green spots or streaks) and may appear as large or small spots or blotches, or as a dappled or "splashed" pattern. [5]

Distribution

The green-and-black poison dart frog is found in humid lowland and submontane forests at altitudes of 0–1,000 m (0–3,280 ft) in southeastern Nicaragua on the Atlantic slope, eastern Costa Rica on the Atlantic slope and in the southwest on the Pacific slope, widely in Panamá, and into far northwestern Colombia in the Chocó Department. [1] [3] [6] An introduced population exists on Oahu, in Hawaii; [1] [3] [4] [7] the species was intentionally introduced there, in 1932, for mosquito control. Later on, it seems to have also become established on Maui. [4]

Poison

The green-and-black poison dart frog, while not the most toxic poison dart frog, is still a highly toxic animal. The very small amount of poison the frog possesses is enough to make a human heart stop beating.[ citation needed ] The green-and-black poison dart frog, as with all poison dart frogs, loses its toxicity in captivity due to a change in diet. This has led some scientists to believe that the green-and-black poison frog actually takes its poison from the mites and other insects on which it feeds. [8]

Behavior

The green-and-black poison dart frog is semi-arboreal, hunting, courting, and sleeping in the trees. Like other dart frogs, they spend much time in the shallow pools of water created in the cup-like leaves of bromeliad plants. The same plants often serve as nurseries for tadpoles [9] . The small pools offer little access to nutrients so the tadpoles often engage in cannibalism. [10] As it is a tiny frog, it cannot obviously leap from branch to branch in the treetops, thus it returns to the ground when it wants to travel. Once on the ground, frogs may travel several miles in an effort to breed, find feeding grounds, or to take care of tadpoles. To assist in climbing, the frog has small, sucker-like discs on the ends of its toes, which create a slight suction as the frogs climb, making their grip mildly adhesive. [9]

Reproduction

Unlike other poison dart frogs, green-and-black poison dart frogs gather in large groups before mating. They squabble over territories; eventually, each individual male frog clears a small patch for himself. Females wander among the males, with the latter then attempting to impress the former with their bird-like mating calls. Captive female green-and-black poison dart frogs are known to fight amongst themselves in the presence of calling males. [11] Once a male has caught the attention of a female, he leads her to a site he has selected for egg deposition. The female lays her eggs, which he then fertilizes. In about 14 days, these hatch into tadpoles. [12] Their parents, typically the male, then carry the tadpoles into the canopy, with the tadpoles sticking to the mucus on their parents' backs. The parents then deposit their tadpoles into the small pools of water that accumulate in the center of bromeliads, and guard the tadpoles while they feed on algae and small invertebrates that inhabit the tiny pool.

Green-and-black poison dart frogs are popular exotic pets due to their small size, bright colors, and intriguing behavior. When they are in captive or zoo settings they are fed crickets, fruit flies. This causes the green-and-black poison dart frog to lose most, if not all, of its toxicity. [13]

<span class="mw-page-title-main">Poison dart frog</span> Family of amphibians

Poison dart frog is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity — a feature derived from their diet of ants, mites and termites— while species which eat a much larger variety of prey have cryptic coloration with minimal to no amount of observed toxicity. Many species of this family are threatened due to human infrastructure encroaching on their habitats.

<span class="mw-page-title-main">Blue poison dart frog</span> Species of amphibian

The blue poison dart frog or blue poison arrow frog is a poison dart frog found in the "forest islands" surrounded by the Sipaliwini Savanna in southern Suriname. Its indigenous Tirio name is okopipi. The name "azureus" comes from its azur blue color. While first described as a valid species and usually recognized as such in the past, recent authorities generally treat it as a morph of D. tinctorius, although a few treat it as a subspecies of D. tinctorius or continue to treat it as its own species. To what extent it differs from the blue D. tinctorius in southern Guyana, adjacent Pará (Brazil) and possibly far southwestern Suriname, also is a matter of dispute, and many herpetologists, as well as many people keeping poison dart frogs in captivity, often have not distinguished these, with all commonly being identified as "azureus".

The strawberry poison frog, strawberry poison-dart frog or blue jeans poison frog is a species of small poison dart frog found in Central America. It is common throughout its range, which extends from eastern central Nicaragua through Costa Rica and northwestern Panamá. The species is often found in humid lowlands and premontane forest, but large populations are also found in disturbed areas such as plantations. The strawberry poison frog is perhaps most famous for its widespread variation in coloration, comprising approximately 15–30 color morphs, most of which are presumed to be true-breeding. O. pumilio, while not the most poisonous of the dendrobatids, is the most toxic member of its genus.

<span class="mw-page-title-main">Frogs in captivity</span>

Frogs have recently become very popular exotic pets as they are generally undemanding, often visually appealing, and can be kept under fairly basic conditions. Many frogs, especially common ones, can be inexpensive, but some specimens can cost several hundreds of dollars. Their food is in most cases easily purchased. Commonly kept pet frogs include ranids, hylids, bufonids, leptodactylids, and dendrobatids.

<i>Anomaloglossus kaiei</i> Species of amphibian

Anomaloglossus kaiei is a species of frogs in the family Aromobatidae, commonly known as the Kaie rock frog. It was named in honor of Kaie, a great Chieftain of the Patamona tribe, who sacrificed himself to the Great Spirit Makonaima by canoeing over the Kaieteur falls in order to save his own people. It is endemic to Guyana where it is known from the Kaieteur National Park and the Pacaraima Mountains. However, as it is found along the Guyana–Brazil border, it is also possibly present in Brazil. This frog shows maternal care: female frogs can provide tadpoles with trophic eggs.

The Evolution of biparental care in tropical frogs is the evolution of the behaviour of a parental care system in frogs in which both the mother and father raise their offspring.
