Frog of the Week

Common Coquí (Eleutherodactylus coqui)

Common_Coquí
leastconcern

Common Name: Common Coquí, Puerto Rican Coquí
Scientific Name: (Eleutherodactylus coqui)
Family: Eleutherodactylidae
Native Location:Puerto Rico
Introduced Location: Costa Rica, Dominican Republic, Virgin Islands, Hawaii, and Florida
Size: Male are 1.1 inches to 1.4 inches (30 to 37 mm)  while females grow from 1.4 to 2 inches (36 to 52 mm)

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.

This is a Wood Frog (Lithobates sylvaticus). They are have a wide range from the Northeast to Alaska.

Here are two America Bullfrogs (Lithobates catesbeianus) I caught. The one on the left is a female while the one on the right is male. Males have yellow coloring on their throat.

Do Toads and Frogs Cause Warts?

IMG_0262

 

My mom always warned me that holding frogs and toads so spread warts on my hands and I’m sure you heard it before too.  Good news, its not true. You can pick up other diseases from holding frogs and toads but not warts. Remember to always wash your hands after handling animals. Now what does cause warts? A type of Human papillomavirus (HPV) causes warts. So go hold all the frogs you want.

Female Frogs Wooing Males with Songs for the First Time

Limnonectes_palavanensis

For most of the frogs and toads in the world, during breeding season, the male frog calls out to the female frogs to attract them. For some species, the female frog sometimes call back. For the first time, researchers have found a species of frog where the female calls out to attract the male frogs. Johana Goyes Vallejos, a Ph.D. candidate from UConn, and colleagues found that the female Smooth Guardian Frogs (Limnonectes palavanensis) often group around a male frog and sing to it.  The male frogs occasionally call back to let them know that they are single and ready to mingle. Besides just calling, the female frogs also abandon their eggs after breeding and let the males take care of them. The sex roles of this species of frogs are reversed from the normal roles. Some may say these frogs are progressive.

New Species

Four New Burrowing Frogs Discovered in the Western Ghats

Kadar Burrowing Frog

Sonali Garg, a PhD student in Delhi University, and her supervisor Professor SD Biju discovered four new species of burrowing frogs. The species were found to be part of the genus Fejervarya in the family Dicroglossidae. There was only one known species of frog in the genus that could burrow – Rufescent Burrowing Frog Fejervarya rufescens that lived all over the Western Ghats. A study from the researchers above showed that the Rufescent Burrowing Frog only lives in a small area of the Western Ghat while other different species of burrowing frogs live in other areas. This was discovered through DNA tests and other lab work.

The frogs are CEPF Burrowing Frog (Fejervarya cepfi), Kadar Burrowing Frog (Fejervarya kadar), Manoharan’s Burrowing Frog (Fejervarya manoharani), and Neil Cox’s Burrowing Frog (Fejervarya neilcoxi)

Numerous other new species of frogs have been found in the Western Ghats recently which makes it a biodiversity hot spot but sadly, many of the frogs are facing threats of extinction there.
