Dendrobates Mysteriosus
''Dendrobates'' is a genus of poison dart frogs native to Central and South America. It once contained numerous species, but most originally placed in this genus have been split off into other genera such as ''Adelphobates'', ''Ameerega'', ''Andinobates'', ''Epipedobates'', ''Excidobates'', ''Oophaga'', ''Phyllobates'' and ''Ranitomeya'' (essentially all the brightly marked poison dart frogs; i.e. excluding the duller genera in the family like ''Colostethus'' and ''Hyloxalus''), leaving only five large to medium-sized species in the genus ''Dendrobates''. All the other genera used to be grouped in with ''Dendrobates'' because it was previously thought that all brightly colored poison dart frogs came from the same ancestor but this has since been proven to be incorrect. ''Dendrobates'' and ''Phyllobates'' evolved conspicuous coloration from the same common ancestor but not the same as any of the other genera listed above. There is accumulating evidence that ''Dendrobates'' are di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrobates Tinctorius
The dyeing dart frog, dyeing poison dart frog, tinc (a nickname given by those in the hobby of keeping dart frogs), or dyeing poison frog (''Dendrobates tinctorius'') is a species of poison dart frog. It is among the largest species, reaching lengths of . This species is distributed throughout the eastern portion of the Guiana Shield and Venezuela, including parts of Guyana, Suriname, Brazil, and nearly all of French Guiana. Etymology The specific name, ''tinctorius'', comes, however not from the variety of colors, but from the legends of some indigenous tribes. It has been said that tribe members used the frog poisons to cause green parrot feathers to grow different colors. Poison Like most species of the genus ''Dendrobates'', ''D. tinctorius'' is highly toxic if consumed. It produces pumiliotoxins and allopumiliotoxins that the frog uses for self-defense. While pumiliotoxins are weaker than their derivative allopumiliotoxins and the batrachotoxins secreted by '' Phyllob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyloxalus
''Hyloxalus'' is a genus of poison dart frogs, family Dendrobatidae. The genus is distributed in Central and South America, from Panama south to Peru (along the Pacific coast), along with Venezuela, Colombia, and Ecuador. They also inhabit the eastern foothills of the Andes in Bolivia to Venezuela, east to the upper Amazon Basin. Description ''Hyloxalus'' are small to moderate-size frogs, ranging from about in snout–vent length. Most species have cryptic, brown, gray, or black dorsal coloration, but some have conspicuous, bright colors (e.g., '' Hyloxalus azureiventris''). A pale oblique lateral stripe is always present. Toe webbing is absent in most species but is present in some species and can even be extensive. Fingers bear narrow to moderately expanded discs. Reproduction Most species deposits their eggs in terrestrial nests and transport the tadpole A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of South America
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic de ...

Poison Dart Frogs
Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow 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, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this feature from their diet of ants, mites and termites. However, other species that exhibit cryptic coloration, and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species th ...

Dendrobates Nubeculosus
The Rockstone poison dart frog (''Dendrobates nubeculosus'') is a poorly known species of dendrobatid frogs endemic to Guyana. As it is known from only one specimen, very little information is currently available on ''D. nubeculosus''. It has been suggested to be one of the most poorly known species in the world. Description ''D. nubeculosus'' is a small to medium-sized poison dart frog; larger than many of its contemporary '' Ranitomeya'' species, but smaller than the other members of the genus ''Dendrobates''. The holotype specimen measures 2.5 centimetres in length, and the species' size range is unknown. It is reasonably certain that, like other members of the genus ''Dendrobates'', ''D. nubeculosus'' females are larger than males, but even this is open to speculation. The holotype is primarily black or dark brown, with irregularly shaped blue splotches on the dorsum, and it is mottled blue and black laterally, with a solid black ventral surface. It is unclear whether, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrobates Leucomelas
The yellow-banded poison dart frog (''Dendrobates leucomelas''), also known as yellow-headed poison dart frog or bumblebee poison frog, is a poison dart frog from the genus ''Dendrobates'' of the family Dendrobatidae. Distribution and habitat ''Dendrobates leucomelas'' is a common poison dart frog found in the northern part of continent of South America, most notably in Venezuela. It is also found in parts of Guyana, Brazil, and the extreme easternmost part of Colombia. This amphibian is normally found in very humid conditions in tropical rain forests, close to fresh water. It is often found on flat rocks, trees, plants (notably bromeliads), and the leaf litter of the forest floor. During the dry season, specimens are known to congregate in damper places, such as under rocks or fallen tree trunks. The ''D. leucomelas natural habitat is tropical, and not subject to great seasonal temperature variations. Typically, temperature variances are related to elevation and time of day, ...

Bumblebee Poison Frog Dendrobates Leucomelas
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queen ...

Dendrobates Auratus
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), is a brightly colored member of the order Anura native to Central America and northwestern parts of South America. This species has also been introduced to Hawaii. It is one of the most variable of all poison dart frogs next to '' Dendrobates tinctorius'' and some '' Oophaga'' spp. It is considered to be of least concern from a conservation standpoint by the International Union for Conservation of Nature. Description The green-and-black poison dart frog has the typical appearance of the members of its family. Males average , while females are slightly larger, averaging an inch or longer. The green-and-black poison frog typically has mint-green coloration; however, this pigment can also be forest, lime, emerald green, turquoise, or even cobalt blue or pale yellow. Mixed with this typically green are splotches of dark color, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
