Pig Frog

Rana grylio

Description:

Pig Frog (Rana grylio) in the rain in wetlands; likely a male due to its large tympanum. << Pig frogs are large frogs, ranging in size from 3.35 to 6.5 in (8.3-6.2 cm). Typically they are grayish-green or brown in coloration with black mottling on the dorsal surface. Pig frogs resemble Green Frogs (Rana clamitans) and Bullfrogs (Rana catesbeiana) but have no dorsolateral folds and the extensive webbing between the toes, reaching the ends of each toe. The belly is light in color and may have dark spots. There may also be a line or row of spots on the back legs. Male pig frogs have a tympanum that is much larger than the eye, while the females have an equivalently sized eye and tympanum. >>

Habitat:

Wetlands: Green Cay Wetlands, Boynton Beach, Florida.

Male pig frogs have a tympanum that is much larger than the eye, while the females have an equivalently sized eye and tympanum. Pig frogs are found throughout Florida and in the Coastal Plain of southern Georgia and southeastern South Carolina. They inhabit permanent bodies of water throughout their range. Open water areas of ponds and marshes are ideal pig frog habitat. Although generally highly aquatic, Pig Frogs may be found moving about on land at night or in wet weather. They breed from late Spring - August and exhibit external fertilization. Up to 10,000 eggs may constitute an egg mass. Eggs hatch in only a few days, but tadpoles may not metamorphose until a year of age. (credit: http://srelherp.uga.edu/anurans/rangry.h......)
