Frog of the Week

Panamanian Golden Frog (Atelopus zeteki)

Common Name: Panamanian Golden Frog, Zetek’s Golden Frog
Scientific Name: Atelopus zeteki
Family: Bufonidae
Location: Panama
Max Size: 2.4 inches (63 mm) for females, 1.8 inches (48 mm) for males

While the name for this cutie is the Panamanian Golden Frog, it is technically a toad since it’s from the family Bufonidae. This froggie is from Panama but possibly not anymore. It has not been seen in the wild since 2007. There are some Panamanian Golden Frogs in zoos and other conservation breeding programs so all hope isn’t lost yet. Chytrid Fungus, over harvesting, and habibat destruction all contribute to the status of the species. It is also referred to as the Zetek’s Golden Frog because the scientific name was named for Dr. James Zetek.

These frogs are diurnal, meaning they are active during the day and rest during the night like us. Another weird thing that they do is that they can climb up to around 10 feet high in trees. Additional weird thing, they wave to communicate.

Common Name: Wallace Flying Frog
Scientific Name: Rhacophorus nigropalmatus
Family: Rhacophoridae
Location: Indonesia, Malaysia, and Thailand
Size: 3.9 inches (100mm) max

The Wallace’s Flying frog is named after Alfred Russel Wallace, who also described the species. The Wallace’s Flying Frog doesn’t really fly (sorry!), it more glides through the air. It fans out it’s highly webbed hands and floats down from one tree to the next or the ground – even more than 50 feet at a time. They are sometimes called Parachute Frogs which more accurately describes what they do. There are other flying frog species, but the Wallace’s Flying Frog is one of the larger species.

For reproduction, the females form a foam nest to protect the fertilized eggs. The nest is made above a body of water in a tree or bush. When the eggs hatch, the tadpoles fall into the water.

Clown Frog (Atelopus varius)

by Brian Gratwicke

Common Name: Clown Frog, Costa Rican Variable Harlequin Toad
Scientific Name: Atelopus varius
Family: Bufonidae
Location: Colombia, Costa Rica, and Panama
Size: 1.6 inches (41 mm) for males, 2.3 inches (60 mm) for females

The Clown Frog or the Costa Rican Variable Harlequin Toad is a small toad from the family Bufonidae. It is from the genus Atelopus, known as the Harlequin Toads or Stubfoot Toad

The Clown Frog has bright colors, which is how they get their name, to warn predators that they are toxic. They have no predators besides a species of fly that lay eggs on the frogs that burrow into the frog and eat it from the inside out.

The Clown Frog and most other Harlequin Toads are endangered of becoming extinct. The two primary causes of the decline are climate change and the spread of Chytrid Fungus.

Frog of the Week

Rapid’s Frog (Limnomedusa macroglossa)

by Axel Kwet

Common Name: Rapid’s Frog
Scientific Name: Limnomedusa macroglossa
Family: Alsodidae
Location: Argentina, Brazil, and Uruguay
Size: 2.1 inches or 55mm

The Rapid’s Frog is the only member of it’s genus, Limnomedusa. They breed in the spring in Southern Hemisphere from late August to the start of February. The males call from under rocks to attract mates. The eggs are laid in isolated ponds in the forests.

While they are only listed as Least Concern, they are threatened by deforestation for agriculture and the creation of dams.

Common Name: Hochstetter’s Frog
Scientific Name: Leiopelma hochstetteri
Family: Leiopelmatidae
Location: New Zealand
Size: 1.5 inches (38 mm) for males, 1.8 inches (47 mm) for females

The Hochstetter’s Frog is a small frog from New Zealand. It was named after the German geologist Ferdinand von Hochstetter. The frog is an ancient frog that still has tail muscle but no eardrum or vocal cords. Interestingly, they can live 30 to 40 years.

The Hochstetter’s Frog is in trouble. Historically, they were located on both of the islands of New Zealand but now they are only found on the northern island. Invasive species introduced to the island have been predating on the frogs and damaging their environment. Pacific rats (Rattus exulans) and Stoat (Mustela erminea) introduced to the island have been eating the frogs. Goats and pigs that were introduced have been eating all the vegetation that the frog likes to hide in.

Common Name: Pichincha Giant Glass Frog, Bumpy Glassfrog
Scientific Name: Centrolene heloderma
Family: Centrolenidae – Glass Frogs
Location: Colombia and Ecuador
Size: 1.2 inches max

The Pichincha Giant Glass Frog lives in the Andes in the cloud forests in Colombia and Ecuador, though no one has recorded seeing one of the frogs in Colombia since 1996.  Even though it’s name says “giant”, its a small frog but its large compared to the other frogs in it’s genus. The Pichincha Giant Glass Frog is a rare frog and is listed as critically endangered. It’s nocturnal and see thru so it’s hard to find in the wild.

The Pichincha Giant Glass Frog is listed as critically endangered because of a few different things. Climate change has moved the clouds in the habitat farther up the mountain, which reduces humidity. Habitat destruction through deforestation for increasing agricultural area, lumbar, and cities is also a major cause of their decline. Last, chytrid fungus could be harming the frogs.



Frog of the Week

Red-Eyed Tree Frog (Agalychnis calidryas)

Common Name: Red-Eyed Tree Frog, Red-Eyed Leaf Frog
Scientific Name: Agalychnis callidryas
Family: Hylidae
Location: Belize, Colombia, Costa Rica, Guatemala, Honduras, Mexico, Nicaragua, and Panama
Size: 3 inches (77 mm) for females and 2.3 inches  (59 mm) for males

Red-Eyed Tree Frogs are a species of true tree frogs that are found from Mexico down to the top of South America. They are a nocturnal species, they sleep on the underside of leaves during the day and are active at during the night. The Red-Eyed Tree Frog tucks it’s legs under it’s body to try to hide the blue color so that the frog blends more into the leaves. If the frog is found by a predator, the frog stares at them with their bright red eyes. Sometimes, this can scare them off. They mainly eat insects such as moths, crickets, etc. For breeding, the females lay their around 40 eggs on leaves and cover them in a jelly-like substance. The eggs are kinda cool in that they can hatch when threatened by predators.

Common Name: Lake Titicaca Water Frog or Titicaca Scrotum Water Frog
Scientific Name: Telmatobius culeus
Family: Telmatobiidae
Location: Bolivia and Peru
Size: 5.4 inches or 137.95 mm

The Lake Titicaca Water Frog is only found in Lake Titicaca, the the largest lake in South America, which is on the border of Bolivia and Peru. The Lake Titicaca frog is an aquatic species of frog. It doesn’t need to come to the surface to breath because the water in the lake is oxygen rich and the skin folds on it’s body. It can come up for air if the water isn’t oxygen rich but the frog’s lungs have adapted to be smaller. Another adaption the frog has is that when it’s threatened, it can releases a secretion that’s gross.

The Lake Titicaca Water Frog is listed as critically endangered. The frog faces many different threats. Humans like to eat the frog because they believe it’s an aphrodisiac.  Pollution in the lake has lead to huge, think thousands, of die offs. Also humans introduced non-native trouts to lake for fishing, and these trouts like to eat the tadpoles.

Common Name: Barking Tree Frog
Scientific NameCraugastor augusti
Family: Craugastoridae
Country Location: United States and Mexico
State Location: Arizona, New Mexico, and Texas
Size: 1.9 – 3.7 inches or 47 – 94 mm

The Barking Tree Frog isn’t a regular tree frog that most people are used to. It doesn’t belong to the family Hylidae, it belongs to Craugastroidae. All the members of the family Craugastroidae are direct developing which means that when they hatch, they are already froglets.

The Barking Tree Frog has three subspecies: Common Barking Tree Frog (Craugastor augusti augusti), Western Barking Tree Frog (Craugastor augusti cactorum), and Eastern Barking Frog (Craugastor augusti latrans).

The frog is named after it’s call that sounds like a barking sound. The species epithet – augusti , is named after Auguste Duméril, a zoologist.

Marbled Snout-Burrower (Hemisus marmoratus)

Common Name: Marbled Snout-Burrower, Marbled Shovelnose Frog, and Mottled Shovelnose frog
Scientific Name: Hemisus marmoratus
Family: Hemisotidae
Location: Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Eritrea, Ethiopia, Gambia, Ghana, Guinea-Bissau, Kenya, Malawi, Mozambique, Namibia, Nigeria, Senegal, Somalia, South Africa, Swaziland, Tanzania, United Republic of Togo, Zambia, and Zimbabwe
Size: 1.9 inches or 49 mm for females, males are 1.3 inches or 34 mm

The Marbled Snout-Burrower pretty much just lives everywhere in Africa that is lower than the Sahara Desert. These frogs are adept at living underground in burrows. They even lay their eggs in burrows underground. They dig underground head first, which is rare since most dig with their hind legs.

Mating for the frogs starts when it starts to rain. The male calls out to the female frogs like most frog species. Males start the amplexus on the female frog while the female still has to dig a burrow for the eggs. The male does the usually stuff and leaves his mate after breeding. The females sit on their eggs to keep them moist. The rain continues to fall during the time the female sits on the eggs over days and eventually the tadpoles hatch and the water level raises enough for the tadpoles to move toward bigger bodies of water. The mother also helps them along the way.
