Although these critters are seldom seen, Pig Frogs (Lithobates grylio) are often heard! These large frogs earned their common name from the pig-like grunting sound they make. You will be able to hear their calls around the boardwalk during their breeding season in the spring and summer months. Pig Frogs are found throughout Florida and they are just one of the several species of frogs and toads at Corkscrew Swamp Sanctuary. -Amy, Education Intern #CorkscrewSwampSanctuary #AudubonFL #PigFrog | Au
