The Pig Frog is named after the male’s mating call that sounds like a pig grunt. Like most frogs in North America, the Pig Frog breeds from early spring to late summer. Generally, the frog breeds in permanent bodies of water such as ponds, lakes, and swamps but have been known to breed in ephemeral ponds, streams, and roadside ditches. Once the female frog chooses a mate, the male frog grasps her from behind in amplexus. Then, the female frog lays her eggs and the male frog fertilizes them. The female frogs can lay up to 15,000 eggs during a breeding season.
The Pig Frog is mostly aquatic, only coming to the edge of bodies of water. There are a few differences between the sexes. The male frogs develop a yellow throat when they reach sexual maturity. The female frogs grow larger than the male frogs which is pretty common in frogs.
The International Union for the Conservation of Nature (IUCN) Red List assesses the Pig Frog as Least Concern for Extinction. The frog has a good sized range and are common throughout it. There are no serious threats to the frog.
