Triangle Treefrog - Dendropsophus triangulum 

This amazing frog with something like paws marks on its dorsum is scientifically named Dendropsophus triangulum (Hylidae), an uncommon species found in the Amazon Basin in Colombia, Ecuador, Peru, northwestern Bolivia, and Brazil.

It is small frog less than 40 mm with several color patterns or morphs, so many that It was described as a new species four times subsequent to its first description in 1869, because different colour morphs were thought to be new species.

In general, Dendropsophus triangulum bears two large pectoral patches that are in contact or nearly so (weak, distinctly apart), a light dorsum with or without a varying number of dark blotches or spots and red venter (lemon-yellow). However, this morph is quite different than the more standard form, more akin to the “giraffe phase” of the sister species Dendropsophus leucophyllatus.

Emei Moustache Toad (Vibrissaphora boringii)

…a species of megophryid frog endemic to parts of  China. It is usually found in moist temperate forests/grasslands, rivers, gardens, and other suitable areas. Like most amphibians the Emei moustache toad feeds mostly on insects, worms, and other small invertebrates. Currently the Emei mustache toad is listed as endangered this is due in part to urban development,habitat loss, and over collection for the pet trade.

Daddy Mimic Poison Frog carrying his tadpole

Ranitomeya imitator (Dendrobatidae), commonly known as Mimic Poison Frog, is a species of frog endemic to north-central Amazonian Peru. The species, which has several color morphs, exhibits some peculiar features. 

They have a monogamous mating system. In fact, the species is the only known monogamous amphibian, with monogamy in the wild confirmed by paternity analysis in studies. They also are strict phytotelm specialists (they only breed in water-holding plants of the genus Heliconia, Dieffenbachia, and Xanthosoma), and as if that were not enough, they have biparental care.

Eggs are normally laid in pairs among the bracts of the host plant. Upon hatching, tadpole transport is carried out by the male, who will later help the female locate tadpoles so she can provide the developing tadpoles with unfertilized food eggs. Males are highly territorial and will defend breeding resources vigorously.

The photo shows a Varadero morph, which was first discovered in 2004 and was heavily smuggled from 2006 to present. This morph appears to be a mimic of the “orange-and-blue” fantastica morph.

Hemiphractus fasciatus

…is a species of hemiphractid frog that occurs in Colombia, Ecuador, Panama and possible Costa Rica. H. fasciatus typically inhabits humid lowland, montane and cloud forests. Individuals are active at night and will prey on other frogs and obsessionally small invertebrates.

Currently Hemiphractus fasciatus is listed as near threatened and faces threats from deforestation and pollution.

Meet the Blue #Glassfrog (Cochranella mache), endemic to the Chocoan #rainforest of #Ecuador and #Colombia.

Until recently it was known only from a small region on the northwestern lowlands of Ecuador, but recently it was reported to occur also across western #Colombia on a paper published in the journal Herpetology Notes (http://www.biotaxa.org/hn).

Truncate-snouted Burrowing Frog - Glyphoglossus molossus 

This bizarre frog is known by several common names, such as Balloon Frog, Blunt-headed Burrowing Frog, Truncate-snouted Burrowing Frog, and Broad-lipped Frog. Its scientific name is Glyphoglossus molossus and belongs to the Microhylidae Family. 

These frogs spend the majority of their time underground but emerge with seasonal rains to breed. The species occurs in north-central Myanmar through most of mainland Thailand through Laos to southern Vietnam.

Glass frog

An unidentified Glass frog (Centrolenidae) from an unknown locality. I suppose it could be a Reticulated Glass Frog, Hyalinobatrachium valerioi, but perhaps you, expert zoologists and herpetologists in Tumblr, could help with the ID of this frog.

Pumpkin Toadlet (Brachycephalus ephippium)

Also known as Spix’s Saddleback Toad, the pumpkin toadlet is a species of “saddleback toad” (Brachycephalidae) that is endemic to montane regions of southeastern Brazil, including parts of the states of Rio de Janerio, Sao Paulo, and Minas Gerias. Pumpkin toadlets typically inhabit subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests, where they will feed on small insects and other small invertebrates. Although B. ephippium is currently listed as least concern it faces some threats due to habitat loss.
