Rabb’s Fringe-limbed Treefrog (Ecnomiohyla rabborum)


Common Name: Rabb’s Fringe-Limbed Tree Frog
Scientific Name: Ecnomiohyla rabborum
Family: Hylidae
Location: Panama
Size: Males: 2.4 to 3.8 inches or 62 to 97 mm Females: 2.4 to 3.9 inches or 61 to 100 mm

The Rabb’s Fringe-limbed Tree frog was a relatively new species discovered, only being found in 2005. It was named in honor of George Rabb and Mary Rabb. After its discovery, the frog was listed as critically endangered because dwindling populations caused by chytrid fungus. Some frogs were collected to attempt the captive breed them. Sadly that failed. The Rabb’s Fringe-limbed Tree Frog went extinct when the last known frog – Toughie, died at the Atlanta Botanical Garden on September 26th, 2016.

Besides the sadness from the loss of a species, the Rabb’s Fringe-limbed Tree Frog was really neat. The male frogs would grow spines on their hands during the breeding season. Males and females would breed in water filled tree holes. Males would watch over the eggs in the tree. Males would also back into the holes at night and let the tadpoles eat some of its skin, similar to what caecillians do. The Rabb’s Fringe-limbed Frog was the one species to do this that we know of.

Common Name: Tusked Frog
Scientific Name: Adelotus brevis
Family: Myobatrachidae
Location: Australia
Size: 1.9 inches or 50 mm for males while 1.5 inches or 40 mm for females

The Tusked Frog is named after bony structures on its lower jaw that look like tusks. Both males and females have these tusks but males have larger ones.

Males fight over females, often locking jaws with each other using their tusks. Females try to select the largest males to breed with. After the female selects a male, males and females lay their eggs in a foam nest. They can lay over 600 eggs in a nest. The male then guards the eggs until they hatch. Females probably selected larger males for breeding because they are better at protecting their nest.

The Tusked Frog is listed as Near Threatened. Dead Tusked Frogs infected with Chytrid Fungus have been found. Hopefully, we can stop Chytrid Fungus before it kills them off.

The Dying Poison Dart Frogs are good parents just like most of the other Poison dart frogs. After mating and laying the eggs, the male and sometimes the female watches over the nest. Then after the eggs hatch, the tadpoles are transporeted on the backs of the parents to water inside bromeliads.

Common Coquí (Eleutherodactylus coqui)


Common Name: Common Coquí, Puerto Rican Coquí

Family: Eleutherodactylidae

Introduced Location: Costa Rica, Dominican Republic, Virgin Islands, Hawaii, and Florida

The Common Coquí is one of the loudest frogs in the world. The male call is as loud as a lawn mower or jack hammer. The name of the frog is also from their call because that’s the sound the male makes. Their call is used to attract females and to warn off males from coming into their territory. A male can approach and then they battle it out with song to see who gets the land.

The Coquí has been introduced to other areas where they are causing problems for native wildlife and people. Their sounds piss people off and to make matters worse, they breed year long.

After breeding, the males protect the eggs until they hatch into full grown froglets, skipping the tadpole stage. The eggs are laid on palm trees or other plants. They even use bird nests to lay their eggs.
