Green Frog (Rana clamitans)
I’m participating in a program called Maryland Amphibian and Reptile Atlas (MARA). MARA is a project run by the Natural History Society of Maryland (NHSM) and the Maryland Department of Natural Resources (MDNR); it is a five-year (January 2010 -2014) atlas of the amphibians and reptiles of Maryland. Amphibians and reptiles are collectively known as “herpetofauna” or “herps.”
I’ve been learning my local herps in the last few years and I’ll share some pictures of herps that I find on my property or in my neighborhood.
Green frogs are sometimes confused with bull frogs. You can’t go by color because their color varies. Look for the prominent dorsolateral ridges that go down the back but not all the way.
Note the large external eardrum called a tympanum (the circle behind the eye).
This picture illustrates relative size.
I love its eyes!
P.S. I believe this is a female because she lacks a yellow throat and her tympanum is not larger than her eye.
