| Description: 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 [Lithobates] clamitans) and Bullfrogs (Rana
[L.] 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. Range
and Habitat: 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. Habits: 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. Call: The call of the Pig Frog
is a low grunting sound, giving the frog its common name. Conservation
Status: Throughout parts of their geographic range, pig frogs are considered
species of concern. In Georgia, pig frogs are considered locally abundant and
are unprotected species. Pertinent Reference:
