Physical Description

Habitat

The Pig Frog is more aquatic than the Bullfrog and will spend most of its time in the water, floating or among the emergent vegetation . It prefers the permanent open waters of ponds , marshes, and old rice fields . Both the Pig Frog and Bullfrog are hunted for their legs .

Ecology: This species occurs in permanent lakes , ponds , swamps , marshes, and streams ; especially those with abundant emergent or floating herbaceous vegetation; old rice fields and rice field reservoirs. Occurs in mangroves in the Bahamas (Schwartz and Henderson 1991). Eggs and larvae develop in permanent bodies of water. In South Carolina, males moved from cypress-hardwood zone to grass-herb zone 40-50 m asl from shore during breeding period; females in grass-herb zone were ready to ovulate (Lamb 1984). When calling, males float in water. (Ref. 61107)

Biology

Diet

The Pig Frog is an opportunistic feeder and will eat insects, worms, small amphibians , and reptiles

Reproduction

Breeds from late spring through August. Fertilization is external. Eggs masses containing up to 10,000 eggs are laid in permanent water. The eggs hatch in several days. The tadpoles may take a year to transform into frogs .

Similar Species

The Pig Frog is often erroneously called a "bullfrog" in southern Georgia.The range of the true Bullfrog and the River Frog completely overlap the range of the Pig Frog. The Carpenter Frog is also found on the Atlantic Coastal Plain, but the adult Carpenter Frog is generally smaller than an adult Pig Frog. The fourth (longest) toe of the Bullfrog, River Frog, and Carpenter Frog does not have webbing extending to its tip. In contrast, the fourth toe of the Pig Frog is completely webbed. The Pig Frog's head is more pointed than the head of the Bullfrog. Other frogs that approach the Pig Frog in size have dorsolateral folds, which the Pig Frog lacks.
