CR
Common Name: Golden Coquí, Coquí Dorado
Scientific Name: Eleutherodactylus jasperi
Family: Eleutherodactylidae
Location: Puerto Rico
Size: Under one inch long

The Golden Coqu is a small frog found only in Puerto Rico but it might even be extinct there. It hasn’t been seen since 1981. The frogs are only found in bunches of bromeliads of the genera Guzmania, Hohenbergia, and Vriesia.

The Golden Coquí is one of the only ovoviviparous frogs in the world. After mating, it becomes pregnant for under a month and then gives birth to small froglets.

Common Name: Couch’s Spadefoot Toad
Scientific Name: Scaphiopus couchii
Family: Scaphiopodidae
Location: Mexico and the United States of America.
US Location: Arizona, California, Colorado, New Mexico, Oklahoma, and Texas
Size: 3 inches or 8 centimeters

Like all Spadefoot Toads, the Couch’s Spadefoot Toad has a keratonized sheath on it’s back feet. They use this “spade” to help them dig. The Coach’s Spadefoot Toad has a more sickle-shaped spade which can help distinguish it from other Spadefoot toads. The toad is named after Darius N. Couch, who collected the first specimen observed by white people.

For most of the year, the Couch’s Spadefoot Toad is found burrowed down underneath the ground. When the rain starts in spring and summer, the frogs come out and breed in temporary ponds.

Green Mantella (Mantella viridis)

endangered

Common Name: Green Mantella, Lime Mantella, and Green Golden Frog
Scientific Name: Mantella viridis
Family: Mantellidae
Location: Madagascar
Max Size: Males around 1 inch or 25 mm and females around 1.2 inch (30 mm)

The Green Mantella is a diurnal (active during the day) species and feeds on insects and other invertebrates that cross it’s path. It’s one of the larger frogs from the genera Mantella. Like most of the common frogs, the Green Mantella lays eggs that eventually hatch into tadpoles. The female lays the eggs in between rocks and in trunks of dead trees and eventually the heavy rains wash them into a body of water.

The Green Mantella is facing extinction because of habitat destruction from forest fires, logging of forests where they live, and overgrazing by livestock. The species suffered heavily from over-harvesting of them for the pet trade but captive breeding has slowed down the harvesting.

Giant Barred Frog (Mixophyes iteratus)

endangered
Common Name: Giant Barred Frog, Giant Barred River-Frog
Scientific Name: Mixophyes iteratus
Family: Myobatrachidae
Location: Australia
Size: around 4.5 inches max (120 mm)

The Giant Barred Frog is one of the largest native frogs in Australia, though it’s just an above average sized frog. It’s found on the eastern coast of Australia from Sidney to Brisbane. The Giant Barred Frog can be distinguished from other Barred Frog species because of it’s nicely colored golden iris.

The Giant Barred frog is a semi aquatic frog and usually live along stream edges in riparian forests. They breed in late spring and summer. After breeding in the stream, the female kicks the fertilized eggs up on the banks of the stream out of the water. When the eggs hatch, the tadpoles either fall or they wiggle their way into the water.

The Giant Barred Frog and a lot of Australian frogs are in endanger of becoming extinct. Clearing of habitat for urban development and timber. Invasive species such as weeds and feral pigs have also degraded the habitat of the Giant Barred Frog.

Common Rain Frog (Breviceps adspersus)

Common Name: Common Rain Frog
Scientific Name: Breviceps adspersus
Family: Brevicipitidae – Rain Frog family
Location: Angola, Botswana, Mozambique, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe
Size: 2.25 inches long

The Common Rain Frog is one of the many rain frog species from Southern Africa. This cute, round frog lives most of it’s live in burrows underground. They are mostly seen after the rains when they leave their burrows to come to the surface to hunt for food and to mate. It’s the reason they are named the Rain Frogs.

Rutenberg’s Reed Frog (Heterixalus rutenbergi)

nearthreatened

Common Name: Rutenberg’s Reed Frog
Scientific Name: Heterixalus rutenbergi
Family: Hyperoliidae
Location: Madagascar
Size: about a inch or 25 mm

The Rutenberg’s Reed Frog is a medium sized frog that is found only in the moorlands in central Madagascar. They live high up in swamps at elevations above 1000 meters.

Not much is known about the frog. Tadpoles and eggs have not been recorded. Males call for females in January so breeding happens during that time and shortly after.

The frog is listed as Near Threatened because of habitat lose. The swamps and bogs that the Rutenberg’s Reed Frog are being turned into rice fields that the frogs don’t like.

Patagonia Frog (Atelognathus patagonicus)

endangered
Common Name: Patagonia Frog
Scientific Name: Atelognathus patagonicus
Family: Batrachylidae
Location: Argentina
Size: 2 inches or 50 mm

The Patagonia Frog has two different forms, an aquatic one and a land form. The aquatic form has  smooth and looser skin than the land form which has more rough, tight skin. The aquatic form also have a orange coloration to their stomach from their different diet from the land form. The aquatic form eats more amphipods from the waters that carotenoids which give the orange hue.

The Patagonia Frog is endangered because of numerous threats. Both Chytrid Fungus and Ranavirus have been problems for the frog. Introduced fish (perch, trouts, and salmons) have also been lame and been eating the frogs.

leastconcern
Common Name: Bumblebee Poison Dart Frog, Yellow-banded Poison Dart Frog, and Yellow-headed Poison Dart Frog
Scientific Name: Dendrobates leucomelas
Family: Dendrobatidae
Location: Brazil, Colombia, Guyana, and Venezuela
Introduced: United States – Hawaii
Size: 1.5 inches or 38 mm

The Bumblebee Poison Dart Frog is found in the tropical forests of South America. They are toxic as their name suggests but the toxin comes from their natural diet of ants. Captive Bumblebee Poison Dart Frogs are non-toxic.

The Bumblebee Poison Dart Frogs performs parental care for their offspring. Males rotate the eggs so the eggs get enough oxygen. Once the eggs hatch, the male carries the tadpoles one by one on his back to small bodies of water.

The Bumblebee Poison Dart Frog is common in the pet trade. It is easy to breed in captivity and fairly easy to take care of. The frogs in the wild make natural groups so housing a few together is fine until they start breeding. Bumblebee Poison Dart Frogs have been found in the wild in Hawaii, though they haven’t done too much damage to the environment. Don’t release pets into the wild.

Long Nosed Horned Frog (Megophrys nasuta)

leastconcern
Common Name: Long Nosed Horned Frog, Malayan horned frog, and Malayan leaf frog
Scientific Name: Megophrys nasuta
Family: Megophryidae
Location: Brunei Darussalam, Indonesia, Malaysia, Singapore, and Thailand
Size: 4.7 inches or 120 mm

The Long Nosed Horned Frog looks like a leaf because it hangs out in the leaf liter of the rain forests that it lives in. It disguises the frog from predators and from prey. If any prey, anything that it can fit in it’s mouth including other frogs, crosses the frogs path, it rockets out to eat it up.

They can be found in the pet trade but most of them are wild caught. Wild caught frogs are both bad for the environment and bad for the consumer. Wild caught animals are more easily stressed out and are shipped often terribly, so if you get a wild caught frog, it might die sooner.

Rocky Mountain Tailed Frog (Ascaphus montanus )

leastconcern

Common Name: Rocky Mountain Tailed Frog, Inland Tailed Frog, and Eastern Tailed Frog
Scientific Name: Ascaphus montanus
Family: Ascaphidae – Tailed Frogs
Location: Canada and the United States (Idaho, Montana, Oregon, and Washington)
Size: Around 2 inches or 50 mm

 

As the name suggests, the Rocky Mountain Tailed Frog is found near the Rocky Mountains and the males posses a tail that they use for reproduction. It is one of the only two species that normally posses a tail in adulthood. The other is the Coastal Tailed Frog. The Rocky Mountain Tailed Frog is a more primitive frog species as it has 9 presacral vertebrae while most have 8 or fewer. This resembles more of the earlier frogs.
