Description
The pig frog is green or grey-green in color, with brown or black blotching. It has fully webbed feet, a sharply pointed nose, and large tympana (eardrums). The Pig frog is sexually dimorphic in size and coloration, the males also have a larger tympanum than the females. It is easily mistaken for various other species of the genus Lithobates, with which it shares its geographic range, including the American bullfrog (Lithobates catesbeiana). Pig frogs grow to a snout to vent length (SVL) of 85 to 140 millimetres (3+1⁄4 to 5+1⁄2 inches). They are known for their loud, deep grunting or snorting sound, reminiscent to the oinking sound of a pig.
What it does
Almost entirely aquatic, they are found predominantly on the edges of lakes, or in cypress swamps and marshes that are heavy with vegetation. They are nocturnal. Their pig-like grunts can be heard during the warm months of the year.
Predation. Pig frogs are prey for water snakes, cottonmouths, herons, ibises, ospreys, American alligators, and humans.
