Common Name: Lowland Burrowing Tree Frog, Northern Casquehead Frog,
Scientific Name: Smilisca fodiens
Family: Hylidae – Tree Frog family
Locations: Mexico and the United States
US Location: Arizona
Size: 2.5 inches

The Lowland Burrowing Tree Frog is not your typical tree frog, it doesn’t live in the trees, it lives in burrows. It lives in the desert so the they need to keep moist. The burrows they live in are very moist. If the moisture leaves during periods of drought, the Lowland Burrowing Tree Frog can create a cocoon out of their outer skin to help keep them moist. After the rains come and the frog doesn’t need the cocoon anymore, the frog will break out and then eat the cocoon.

vulnerable
Common Name: Granular Poison Frog
Scientific Name: Oophaga granulifera
Family: Dendrobatidae – Poison Dart Frog family
Locations: Costa Rica and Panama
Size: .7 – .8 inches (18-22 mm)

The Granular Poison Frog is a diurnal (active during the day) species of frog. The males of the species are highly territorial in regards to their calling and breeding sites, even attacking other males. After breeding, the males will brood the eggs and keep them moist. After the eggs hatch, the females transport the tadpoles on their back to a water-filled plant. The females will lay unfertilized eggs for the tadpoles to feed on. The Granular Poison Frog is listed as Vulnerable by the IUCN due to habitat destruction and habitat fragmentation. Logging, agriculture, and expanding urbanization are causing this.

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.

Smoky Jungle Frog (Leptodactylus pentadactylus)

leastconcern

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.
