Common Name: Green Poison Dart Frog, Green and Black Poison Dart Frog
Scientific Name: Dendrobates auratus
Family: Dendrobatidae
Native Locations:  Colombia, Costa Rica, Nicaragua, and Panama
Introduced Location: United States – Hawaii
Size:  females – 1.6 inches / 42 mm, males  – 1.5 inches / 39 mm

The Green and Black Poison Dart Frog is a very popular pet frog because of its bright colors and being diurnal (active during the day).  The frog is poisonous in its native habitat but in captivity, it is not since the poison comes from their diet. Not all Green and Black Poison Dart Frogs are green, they can also be blueish in color.  Poison Dart Frogs are one of the harder types of frogs to keep as a pet, so do not buy them unless you have experience.

Like other members of the genus Dendrobates, the Green Poison Dart Frog males provide parental care for their offspring. The males rotate the eggs and remove fungus on them until they hatch into tadpoles. Then the males transport the tadpoles on his back to new bodies of water.

Common Name: Northern Leopard Frog
Scientific Name: Lithobates / Rana pipiens
Family: Ranidae
Location: United States and Canada
Size: 4.3 inches

The Northern Leopard Frog used to be a incredibly common frog in the USA and Canada but human activities have decreased their numbers. Pesticides, pollution, habitat destruction, and the spread of diseases are some of the reasons why their numbers aren’t what they used to be.  The Northern Leopard Frog gets its name from the spots on its body. The frog can vary in color from bright green to a brown color.

Common Name: Túngara Frog
Scientific Name: Engystomops pustulosus
Family: Leptodactylidae
Location: Belize, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Trinidad and Tobago,  and Venezuela
Size: 1.4 inches or 35 mm

The Túngara Frog is found throughout all of Central America down to South America. The frog is often studied because of their complex mate selection. Females don’t always select the “best” mate choice. You can read more in this article.

Túngara Frogs breed year round in whatever body of water they can find. Males call to the females while floating in these bodies of water. Once the female selects a mate, they move close to shore and make a lay their eggs in a foam nest that they make. These foam nests help protect the eggs from drying out.

Common Name: Smoky Jungle Frog
Scientific Name: Leptodactylus pentadactylus
Family: Leptodactylidae
Location: Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, and Suriname
Size: 7.2 inches / 185 mm

The Smoky Jungle Frog is one of the largest frogs in the world, with females reaching over 7 inches long while males are slightly smaller. The frogs have a long life span that can reach over 15 years.

Mating takes place during the rainy months. Females form foam nests that the eggs are laid into to protect them from the environment. Not all eggs are fertilized, when the tadpoles emerge, they eat the unfertilized eggs.

The super power of the Smoky Jungle Frog is its anti predator defense system where its able to secrete vast amounts of mucus when attacked. Besides the mucus being gross,  it is also toxic so any predator won’t want to eat them.

Common Name: Ornate Horned Frog, Bell’s Horned Frog, and Argentina Horned Frog
Scientific Name: Ceratophrys ornata
Family: Ceratophryidae
Location: Argentina, Brazil, and Uruguay
Max Size: 6.5 inches for females, 4.5 for males

The Ornate Horned Frog is part of the Horned Frog family which are often called the Pacman Frogs. They resemble Pacman because their heads are most of their body and they love to eat.  The Ornate Horned Frog is pretty common in the pet trade and they are fairly easy to take care of.

The Ornate Horned Frog is a sit and wait predator. In the wild, they bury part of themselves and wait for prey to walk in front of them. They spend most of their life like this.

When fall and winter comes, the frog burrows down into the ground where it then creates a cocoon-like structure to keep in moisture and heat. It stays below the ground until spring. During the spring time, the frogs mate and lay their eggs in temporary pools of water.  Interestingly, the tadpoles of the Ornate Horned Frog can make distress calls in and out of water. It’s the first known vertebrate larval form that can make sounds.

The Ornate Horned Frog is listed as Near Threatened. Their habitat is destroyed to make ways for farms and villages. If their habitat isn’t destroyed for farms or villages, pollution from nearby villages and farms harm their habitat.

Common Name: Hula Painted Frog
Scientific Name: Latonia nigriventer
Family: Alytidae
Location: Israel
Size: 5 inches for females, 4.7 inches for males

The Hula Painted Frog was thought to be extinct before being re-discovered in 2011. Its only found in the marshes surrounding Lake Hula in Israel.  The lakes and marshes were drained way back in the 50s which lead researchers to believe that the frog was extinct. The lake area has now become a reserve for wildlife which has helped the species.

The Hula Painted Frog is the only living species in the genus Latonia. There are a few other species in the family but they are all extinct and only known from fossils.

Common Name: Emerald Glass Frog, Nicaragua Giant Glassfrog
Scientific Name: Espadarana prosoblepon
Family: Glass Frog Family – Centrolenidae
Location: Colombia, Costa Rica, Ecuador, Nicaragua, and Panama
Size: 1.2 inches or 31 mm for females, 1.1 inches or 28 mm for males

The Emerald Glass Frog is a beautiful frog from Central and South America. Like other glass frogs, the Emerald Glass Frogs skin is see through, hence the name and they live their lives in the trees. The Emerald Glass Frog even mates in the trees.

Male Emerald Glass Frogs claim territory over hanging trees during the mating season which is from May to November (during the rainy season).  If another male enters the territory, a fight may break out. These fights can take over 30 minutes long and last until one frog falls from the tree or gives up.

When the female enters the territory, the male jumps on her back and they start to reproduce. They lay their eggs on leaves or rocks overhanging streams and then they leave. The eggs hatch a week or so later and the tadpoles then fall into the stream.
