The Transvaal Short-headed Frog aka Blaasop or Rainfrog, Breviceps adspersus, is a common burrowing frog native to southern Africa. It has a round, globular body with a small head and short, robust limbs. When disturbed it inflates its body, assuming a balloon-like appearance, and excretes a sticky toxic substance from its skin. Because of the greater size or rather globular female, the male must glue himself to the female’s back during mating. The female then burrows into the ground with the male stuck to her…
Ameerega trivittata, formerly Epipedobates trivittatus, is a species of frog in the Dendrobatidae family, commonly known as the Three-striped poison frog. It is found in Bolivia, Brazil, Colombia, Guyana, Peru, Suriname, and Venezuela ; possibly Ecuador, and possibly French Guiana .
As with all of the dendrobatine poison dart frogs, the main toxin secreted by A. trivittata is pumiliotoxin. Wild A. trivittata also have the ability to convert their toxins into allopumiliotoxins. Direct contact with a wild three-striped poison dart frog can cause severe cramping, local paralysis, and seizures. The three-striped poison dart frog is believed to be the second-most toxic member of the Ameerega genus .
This species is commonly known in Spanish as Sapito Dardo Trilistado.
Forward-facing eyes are a trait shared by most centrolenids, including this Red-spotted Glass frog, Nymphargus grandisonae (Centrolenidae). These help the frogs calculate distances in their arboreal environment.
Odontobatrachidae • The First Endemic West African Vertebrate Family – A New anuran Family highlighting the uniqueness of the Upper Guinean Biodiversity Hotspot 
Higher-level systematics in amphibians is relatively stable. However, recent phylogenetic studies of African torrent-frogs have uncovered high divergence in these phenotypically and ecologically similar frogs, in particular between West African torrent-frogs versus Central (Petropedetes) and East African (Arthroleptides and Ericabatrachus) lineages.
Because of the considerable molecular divergence, and external morphology of the single West African torrent-frog species a new genus was erected (Odontobatrachus). In this study we aim to clarify the systematic position of West African torrent-frogs (Odontobatrachus). We determine the relationships of torrent-frogs using a multi-locus, nuclear and mitochondrial, dataset and include genera of all African and Asian ranoid families. Using micro-tomographic scanning we examine osteology and external morphological features of West African torrent-frogs to compare them with other ranoids…
This Toad Grows a Spiky Mustache and Stabs Rivals for the Ladies
by Matt Simon
This dapper little amphibian doesn’t just walk into the breeding season unarmed. For one chaotic month a year in China, males grow extremely sharp facial spikes, which they use to shank rivals for the choicest nesting sites.
Some 90 percent of all males end up injured. Victors win the right to mate. Losers shuffle away and seriously consider never growing a mustache again, because maybe it wasn’t a good idea in the first place and they were just curious how it would look, like that one time when I was in high school.
Their weapons are called, no joke, nuptial spines, and they’re made of keratin — the same stuff as your fingernails. The spines grow straight through the toad’s skin, and although they will at times pop off in combat, they’ll simply sprout once again, only to fall off at the end of the breeding season.
And if you think that mustache is handsome, wait until you hear about the toad’s other transformations. Its forearms will actually buff up considerably in the mating season, like a bro during a Jersey Shore summer. This, according to evolutionary biologist Cameron Hudson, likely aids both in combat and in amplexus: the amphibian sexy-time, in which strong forelimbs will help the male grasp the female…
Rediscovery of a “Lost” Andean Toad after 43 year disappearance
Scientists discover a relict population of bizarre toads in rapidly disappearing cloud forests of northwest Ecuador
A team of U.S. and Ecuadorian scientists working in the remote cloud forests of northwest Ecuador with the international non-profit The Biodiversity Group have rediscovered a population of the once thought extinct Tandayapa Andean Toad (Andinophryne olallai). The rediscovery, reported in an article published in the open-access journal Amphibian and Reptile Conservation, marks the first time the species has been seen in 43 years and sheds light on the species natural history and conservation status for the first time. The study is authored by scientists from The Biodiversity Group, Museo de Zoología of Catholic University of Ecuador and the local community organization Manduriacu Cooperative.
The toad genus Andinophryne is made up of three barely-studied and endangered species restricted to Andean cloud forests of western Ecuador and Colombia. Of the three species, the Tandayapa Andean Toad is the least known, with the only previous observation being the individual from the original species description from Tandayapa, Ecuador in 1970. Its scarcity earned the species a spot on the World’s “Lost Frogs” List by Conservation International…
Beelzebufo ampinga was a particularly large species of prehistoric frog first identified in 2007. Common names assigned by the popular media include “Devil Frog" and "The Frog From Hell”. Fossils of Beelzebufo have been recovered from strata of the Maevarano Formation in Madagascar, dating to the late Cretaceous Period, some 70 million years ago. The species may have grown to over 40 cm (16 in) and 4 kgs (9 lb), larger than any living frogs…
Sound expert Julian Treasure created an online competition to discover what the most ‘beautiful sound in the world’ was. Out of all the submissions, a sample recorded at dusk in Malaysian near a swamp was judged to be most beautiful.
"It was a sound of a swamp with a frogs singing. The most amazing, rich recording of just life — teeming life," Treasure said. "And listening to it you really get the sense of nature at its fullest, and most abundant and most exciting."
Welcome to Snapshots in Time, a long-term Citizen Science project aimed at mobilizing people to monitor the timing of Spotted Salamander (Ambystoma maculatum) and Wood Frog (Lithobates sylvaticus) breeding throughout the respective ranges of these species.
The purpose of this project is to use the data collected by on-the-ground citizens year-after-year to investigate possible effects of climate change on the timing of reproduction…
Frogs and Bats Use Water Ripples to Eavesdrop on Frog Calls
by Mary Bates
Communication requires a sender, a receiver, and a message. But communication doesn’t take place in a vacuum. Often, there are unintended receivers listening in and unintentional messages getting across.
Illustrating just how complicated sending a message can be is the example of the túngara frog (Physalaemus pustulosus). Male túngara frogs, native to Central and South America, gather at night in shallow ponds and call to attract females. They space themselves out carefully, each male defending a small calling site. Competition for females is serious business, and males will fight if one horns in on another’s chosen calling site.
A new study shows how the male túngara frog’s call inadvertently creates a multisensory message that can be exploited by both rivals and predators.
In addition to the acoustic component of the male’s call, the visual of his vocal sac inflating and deflating provides an extra cue in female attraction and male competition. But the pulsating sac also creates a third signal component — ripples on the surface of the water…
Voracious, exotic bullfrogs are destroying native wildlife across the western United States.
In California bullfrogs eat and out-compete animals like the endangered California tiger salamander and California red-legged frog. Bullfrogs are imported into California for food, pets or dissection, but many escape and wreak havoc on native ecosystems.
If you’re in California, take action and tell Governor Jerry Brown to ban the import and sale of bullfrogs in California…
Bryophryne hanssaueri is a tiny terrestrial-breeding frog endemic to the upper cloud forests of Manu National Park, in Peru. It inhabits moss mats covering the forest floor, which they use for retreat and reproduction…
