Ranitomeya amazonica is a poison dart frog in the genus Ranitomeya . [3] It was first described by Rainer Schulte in 1999 as Dendrobates amazonicus when he separated it from Dendrobates ventrimaculatus , primarily on the basis of call characteristics. The validity of the species has been debated, but further studies, also including genetic data, support its validity. [4]
This frog has been found in Peru, Colombia, French Guiana, Brazil, and Guyana. Scientists may infer that it also lives in Suriname. It is diurnal and lives in primary forest and older secondary forest. Most of its habitats are pristine, but it has shown some tolerance to disturbance. It has been observed between 0 and 200 meters above sea level. [1]
It is listed as "Least Concern" on the IUCN Red List based on the assessment from 2023. What threat it faces comes from habitat loss associated with agriculture and cattle cultivation. [1]
An assessment of fifteen frogs in French Guiana showed that about 13 percent were infected with the fungus Batrachochytrium dendrobatidis , which causes chytridiomycosis. [1]
This frog has been seen on the international pet trade, but because it is also raised in captivity, it is difficult to tell whether any given frog was raised in captivity or captured in the wild. [1]
The frog occurs in at least two protected parks, Reserva Nacional Alpahuayo Mishana and Reserva Comunal Tamshiyacu-Tahuayo, and scientists infer it could live in many more. [1] [5]
Ranitomeya amazonica is 16–19 mm long with smooth, black skin. The torso is laterally striped orange or red while the legs and arms feature a mesh of blue, grey or green on black. There is no explicit sexual dimorphism in this frog, but females tend to be slightly bigger than males. [6]
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 Tiriyo name is okopipi. The name "azureus" comes from its azure 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, is also a matter of dispute, and many herpetologists, as well as many people keeping poison dart frogs in captivity, have not distinguished these, with all commonly being identified as "azureus".
The yellow-banded poison dart frog, 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.
Ranitomeya imitator, is a species of poison dart frog found in the north-central region of eastern Peru. Its common names include mimic poison frog and poison arrow frog, and it is one of the best known dart frogs. It was discovered in the late 1980s by Rainer Schulte who later split it up into more subspecies; describing each as a specific color morph, and sometimes having a separate behavioral pattern. The acoustics, morphs, and behavior of the species have been extensively researched.
The red-headed poison frog, fantastic poison frog, or crowned poison frog is a species of frog in the family Dendrobatidae. It is endemic to Peru and found in the northern San Martín and Loreto Regions.
Ranitomeya flavovittata is a species of frog in the family Dendrobatidae. It is endemic to Peru and known with certainty only from the Loreto Region where its type locality is.
The blue-bellied poison frog or bluebelly poison frog is a species of frog in the family Dendrobatidae.
Ranitomeya vanzolinii, also known as the Brazilian poison frog or spotted poison frog, is a species of frog in the Ranitomeya genus, from the poison dart frog family, Dendrobatidae. It is found in the Amazonian rainforests of Brazil and Perú, and possibly Bolivia.
Adelphobates is a small genus of poison dart frogs. They are found in the central and lower Amazon basin of Peru and Brazil, possibly Bolivia. It was originally erected as a sister group to the Dendrobates and Oophaga genera. The validity of the genus is still being discussed, with the alternative being "Dendrobates galactonotus group" within Dendrobates. One species originally placed in this genus as Adelphobates captivus has since been moved to the genus Excidobates erected in 2008.
Ranitomeya is a genus of dart poison frogs found in Panama and South America south to Peru and Brazil, possibly into Bolivia.
The Amazonian poison frog, known in French as dendrobate à ventre tacheté, is a species of poison dart frog. It is native to South America, where it can be found in Brazil, southeastern Colombia, Ecuador, French Guiana, and Peru.
Ranitomeya variabilis, formerly known as Dendrodates variabilis, is a species of small poison dart frog distributed in northern Peru, along the eastern slope of Andes in the upper Rio Huallaga drainage basin. Its common name, Zimmerman's poison frog, is named after Elke Zimmermann, a German zoologist who described the morph of this species and differentiated it from D. ventrimaculatus. The species was formerly considered to be synonymous with Ranitomeya ventrimaculata.
Ranitomeya sirensis or the Sira poison frog is a species of poison dart frog found in the Amazonian rainforests of northern Bolivia, westernmost Brazil (Acre), and eastern Peru.
The Rockstone poison dart frog 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.
Andinobates is a genus of poison dart frogs from Ecuador, Colombia and Panama. It contains species formerly classified in the genus Dendrobates and in 2006 transferred to the genus Ranitomeya. In 2011 Twomey, Brown, and their colleagues erected the genus Andinobates for a group of 12 species of Ranitomeya. Andinobates frogs can be distinguished from their sister taxon Ranitomeya anatomically in that their 2nd and 3rd vertebrae are fused. They show no limb reticulation, which is present in most species of Ranitomeya.
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.
Ranitomeya summersi, sometimes referred to as Summers' poison frog, is a species of poison dart frogs found in the central Huallaga River drainage and adjacent Cordillera Azul National Park in central Peru. Before 2008, the species was considered a subspecies of Ranitomeya fantastica. The IUCN considers it an endangered species because of limited habitat range, habitat loss, and collection for the pet trade.
Ranitomeya benedicta, sometimes called the blessed poison frog, is a species of poison dart frogs found in the lowland rainforest of the Pampas del Sacramento in southern Loreto and eastern San Martín Region, northeastern Peru. Before 2008, the species was considered a subspecies of Ranitomeya fantastica. The IUCN considers the species vulnerable because of limited habitat range, habitat loss, and collection for the pet trade.
Andinobates tolimensis, the Tolimense poison frog, is a species of amphibian in the family Dendrobatidae, endemic to Colombia in the outskirts of Falan and north of the department of Tolima. Previously it was included in the genus Ranitomeya, but was reclassified in Andinobates, along with 11 other species. It is threatened by habitat loss. It is toxic to humans and when captured will excrete a milky substance.
Ranitomeya uakarii, known as the red uakari poison frog, is a species of frog in the family Dendrobatidae. The species can be found in the Amazon basin, specifically in Brazil and Peru.
Ranitomeya toraro, the Apuriná poison frog, is a species of frog in the family Dendrobatidae. It is endemic to Colombia and Brazil and possibly nearby Peru.
