Common Name: Bhupathy’s Purple Frog
Scientific Name: Nasikabatrachus bhupathi
Family: Nasikabatrachidae
Location: India
Size: 2 inches

There used to be just one species of Purple Frog until genetic tests showed there was another species: the Bhupathy’s Purple Frog. Some of the other differences between the two species are their calls and breeding seasons. Bhupathy’s Purple Frog breeds during the northeast monsoon while the Purple Frog breeds during the southwest monsoon.

The Bhupathy’s Purple Frog spends their life underground. They rarely come to the surface and its generally only to mate. The conservation status of the frog has not be accessed but the regular Purple Frog is listed as Endangered so its likely the Bhupathy’s Purple Frog isn’t doing well either. The frog is named after Dr. Bhupathy Subramaniam, a famous herpetologist who died accidentally from a fall.

Gopher Frog (Lithobates capito)

nearthreatened
Common Name: Gopher Frog
Scientific Name: Lithobates capito
Family: Ranidae
Location: USA – Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee (extremely rare)
Size: 2.5 – 3.75 inches

The Gopher Frog gets it name from the fact that they live in Gopher Tortoise’s (Gopherus polyphemus) burrows. Sadly, both the Gopher Frog and the Gopher Tortoise aren’t doing so hot. The habitat that these buddies used to live in was destroyed to make room for development. Fire suppression is another cause of the Gopher Tortoise and Frog decline. The tortoise enjoys wiregrass and herbaceous vegetative covers which gets decreased when invading hardwoods take over due to the fire suppression. It also changes the the quality of the temporary breeding pools that Gopher Frogs use.

The Gopher Frog has two subspecies – the Carolina Gopher Frog (Rana capito capito) and the Florida Gopher Frog (Rana capito aesopus).  The Florida Gopher Frog is darker in color, ranging from grey to brown while the Carolina Gopher Frog is lighter, varying from white, brown, and yellow.

The Fowler’s Toad is found mostly in the eastern United States and barely in southern Canada. They breed during summer, from June to August, and the farther south they are, the later they breed. They can lay between 2000 to 10000 eggs in a clutch.

Common Name: Cranwell’s Horned Frog, Chacoan Horned Frog
Scientific Name: Ceratophrys cranwelli
Family: Ceratophryidae

The Cranwell’s Horned Frog is a common frog in the pet trade. They have been bred to be a variety of colors but are naturally dark green and brown. They are often referred to as a Pacman Frog because of its resemblance to the video game character. They are sit and wait predators, where they will sit in one spot for hours until something moves in front of them and they snap up and eat it. They eat pretty much any animal that they can fit in their mouths.

In the northern part of their range where it snows, they survive by laying in the bottom of ponds, streams, and pools.

Common Name: Tiger-striped Leaf Frog
Scientific Name: Phyllomedusa tomopterna
Family: Hylidae
Location: Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela
Size: 2.3 inches or 60 mm

The Tiger-striped Leaf Frog is a beautiful frog found in the Amazon Rain Forest. These frogs are arboreal (living in trees) and nocturnal (active during the night). Since they live in trees, they also reproduce in the trees and lay their eggs on leaves hanging over pools of water. Once the eggs hatch, the tadpoles drop into the water where they stay until they fully complete their metamorphosis.

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)

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.
