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]

Distribution and habitat

This frog has been found in Peru, Colombia, French Guiana, Brazil, and Guyana. Scientists may infer that it also lives in Surname. 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]

Conservation status and threats

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]

Description

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 and northern Pará (Brazil). Its indigenous Tirio 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.

Ranitomeya imitator, is a species of poison dart frog found in the north-central region of eastern Peru.

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.

Peruphasma schultei, known as the black beauty stick insect and the golden-eyed stick insect, is a species of phasmid found in the Cordillera del Condor region of northern Peru. In the wild the insect feeds on Schinus plants, but will feed on privet, Aucuba japonica and honeysuckle in captivity. In Peru they are only known to exist in a region of less than 5 hectares, usually on volcanoes or mountains, but since their discovery they have become increasingly popular as pets worldwide due to their unusual colouration and they are now bred regularly in captivity.

<i>Andinobates</i> Genus of amphibians

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.
