Mi Príncipe

While on our first field trip to Caw Caw Interpretative Center we stumbled upon two pig frogs that had made their way into one of our traps. The pig frog, Rana grylio, is highly aquatic, thus us finding it in the marsh at Caw Caw. They are supposed to be tentative of humans and difficult to catch, but the ones we caught were happily held and examined (as long as we kept them moist of course).

The pig frog we caught was either a large juvenile or small adult, since it's length was approximately three inches. Based on the size of the tympanum being approximately the same size as it's eye, I would say that the frog is a female, since males tend to have a tympanum almost twice as large as it's eye. As stated earlier the frog's behavior was calm, except when it started to become dry it would try to hop away, but who doesn't get irritated when they are thirsty? The marsh where we found the pig frogs, was a freshwater marsh separated by a land barrier from a saltwater marsh. Below is a picture of part of the freshwater marsh.

I was shocked when the frogs were so calm while being held, because usually from my experience they always want to get away. So I definitely stole this opportunity to see if this frog was my prince...
