… is endemic to slow-moving streams and moist forests of sub-tropical and tropical Ecuador. This species was once considered extinct as a result of the widespread amphibian chytrid fungus that has decimated many amphibian populations. However, it was rediscovered in October 2010 during an expedition to Southwestern Ecuador sponsored by Conservation International, the IUCN Amphibian Specialist Group, and Global Wildlife Conservation (GWC).
The African Common Toad or Guttural Toad (Amietophrynus gutturalis) has not before been seen in the desert country of Quatar, located on the Arabian Peninsula.
Science teacher Henry Kavale likes to go for a spin on his bike at weekends, and while pedalling through the marshes at Al Khor recently he saw something hopping around in the waterlogged undergrowth. A toad.
On other rides he saw more of the creatures. So last weekend he sent some of his Year 10 students from Al Khor International School out to see if they could catch one for identification.
It didn’t take long; within a few minutes Henry’s son Eugene had triumphantly nabbed one of the amphibians and taken it home to be photographed…
Sierra Nevada Frog and Toad Proposed for Endangered Species Act Protection, With 2 Million Acres of Protected Habitat
CBD media release
SACRAMENTO, Calif.— In accordance with an agreement with the Center for Biological Diversity, the U.S. Fish and Wildlife Service today proposed federal Endangered Species Act protection for Sierra Nevada yellow-legged frogs and Yosemite toads, along with more than 2 million acres of proposed critical habitat across the Sierra Nevada mountains. The Service also proposed protection for a population of mountain yellow-legged frogs that lives in the southern Sierra Nevada.
These protections are the result of a 2011 agreement between the Center and the Service to speed up endangered species protection decisions for 757 imperiled animals and plants around the country. So far, 56 species have been fully protected and another 96 have been proposed for protection under the settlement agreement. The amphibian species proposed for listing today have been waiting more than a decade for protection.
“This is great news for the only native amphibians of the high Sierra Nevada, which have suffered massive declines in recent decades and disappeared from most of the places where they once lived,” said the Center’s Jeff Miller…
World’s Grooviest Endangered Frog Bred in Captivity for First Time
by Julia Whitty
Great news today that the endangered limosa harlequin frog (Atelopus limosus) has been bred in captivity for the first time. This unbelievably groovy-looking character is native to the tropical lowland forests of eastern Panama. Six partner organizations forming the Panama Amphibian Rescue and Conservation Project have been caring for 65 adult limosa harlequin frogs, including:
Figuring out how to arrange rocks in the breeding tank to create the submerged caves like those the frogs prefer in the wild
Getting the right highly oxygenated, gently flowing water between 22 and 24 degrees Celsius (71-75 degrees Fahrenheit)
Recreating the tadpoles’ natural food—algal film growing on submerged rocks—by painting petri dishes with a solution of powdered spirulina algae and allowing it to dry
In other words, awesome Mary Poppins babysitting duties.
The project has successfully bred other challenging endangered species, including crowned treefrogs (Anothecaspinosa), horned marsupial frogs (Gastrothecacornuta), and toad mountain harlequin frogs (A. certus)…
Smithsonian Conservation Biology Institute and Collaborators Successfully Breed Endangered Frog Species
Smithsonian press release
The limosa harlequin frog (Atelopus limosus), an endangered species native to Panama, now has a new lease on life. The Panama Amphibian Rescue and Conservation Project is successfully breeding the chevron-patterned form of the species in captivity for the first time. The rescue project is raising nine healthy frogs from one mating pair and hundreds of tadpoles from another pair.
“These frogs represent the last hope for their species,” said Brian Gratwicke, international coordinator for the project and a research biologist at the Smithsonian Conservation Biology Institute, one of six project partners. “This new generation is hugely inspiring to us as we work to conserve and care for this species and others.”…
Critically endangeredHouston Toads (Bufo houstonensis) have had a rough few years, with massive devastating wildfires and severe drought, but things are looking better than expected. They have been hanging out at breeding ponds this week, and dozens more of these endangered toads were found in Bastrop State Park, than last year.
Find out more about recovery efforts for this species:
The Puerto Rican Crested Toad (Bufo lemur) is a species of toad found only in Puerto Rico, and is the only species of toad native to Puerto Rico. The species formerly occurred in Virgin Gorda. It is listed as a threatened by the US Fish and Wildlife Service due to habitat loss and introduced species. The IUCN has the species listed as critically endangered, although this classification is in question as recent hurricanes that have produced several inches of precipitation have revealed large populations in suitable habitat.
Can someone help me identify this unknown froggie I photographed in the Bocas Del Toro archipelago in Panama?
He was indeed strange looking and the only one I saw. At first it looked like his back legs had “melted” onto the leaf. He does have beautiful green eyes. (Click to enlarge) Anyone?
I’m pretty sure that this is the Green Climbing Toad (Incilius coniferus), obviously they are not always completely green. It’s a species of small arboreal toad, found int he forests of central and northern South America.
Endangered Tadpoles on a Mission to Help Restore Their Species
by Live Science staff
Thousands of tadpoles are on a journey from Cleveland to Puerto Rico as part of an effort to save their critically endangered species.
The traveling tadpoles are Puerto Rican crested toads, and the Cleveland Metroparks Zoo is part of the Species Survival Plan that works to breed the toads and release them back to the wild. The plan is managed by the Association of Zoos & Aquariums.
“The Puerto Rican crested toad Species Survival Plan has been very successful,” said Lynn Koscielny, the associate curator of animals at the zoo. “Field researchers in Puerto Rico have observed toads with transponders that were released into the wild returning to the protected ponds to reproduce.”

Clear evidence of major declines of amphibians in the United States and around the world has been established. The estimated rate of worldwide amphibian extinction since 1980 is thought to be 105 times higher than the background rate (McCallum, 2007). These declines threaten the extinction of 30 percent of the world’s approximately 7,000 amphibian species. This constitutes the greatest extinction event since the “Pleistocene extinctions” 10,000 years ago.
The number of extinctions in the United States is not as extreme as in other parts of the world, but serious declines have been documented (for example, Mountain Yellow-legged Frog; Yosemite Toad; Boreal Toad; and Mississippi Gopher Frog). Every ranid frog species in the western United States is on a list of concern.
To date, the most comprehensive source of information on declines for amphibians in the United States is a species by species assessment summarized by Bradford (2005) that suggests about 42 percent of species are threatened or declining. A similar approach used by Stuart and others (2004) to classify the status of amphibians globally, suggests that 21 percent of species in the United States are declining…
Dec. 12, 2012 — It may be possible to stop the spread of can toads into new areas of Australia according to new research published December 12 in the Journal of Applied Ecology.
by Science Daily staff
One of the lead authors of the study, James Cook University’s Dr Ben Phillips, said that their work, which involved an international team of scientists, showed that artificial waterbodies installed by graziers acted as critical stepping-stones for the toad invasion.
“By removing these waterbodies in key locations it is possible to halt the spread of toads,” he said.
Cane toads are currently spreading into the vast Kimberley region of north-western Australia and will likely completely occupy this region within ten years.
Dr Phillips said that “by removing around 100 artificial waterbodies, toads can be prevented from occupying 268,000 square kilometres of their potential range in Western Australia, which is an area larger than Great Britain.”…

About 2,000 Kihansi spray toads have been reintroduced into the Kihansi Gorge in Tanzania after the animal was declared extinct in the wild. This is the first example of an amphibian species that had been declared extinct in the wild being repatriated to its native habitat, according to a release from the Wildlife Conservation Society (WCS), an environmental group which has led the effort to return the toads to their home.
The Kihansi spray toad is gold-colored, with pale white, almost translucent skin on its abdomen that makes its intestines visible. The toad belongs to a unique group of amphibians that give birth to live young in lieu laying eggs weighs. After delivering their young, the toads carry the babies on their backs.
In 1996, a population of the tiny toads was first found living near the bottom of a waterfall in the Kihansi Gorge, where spray from the pounding of water on rock created a unique micro-habitat in which the animals thrived…
