Pickerel Frog

Description

This species can be found throughout central Mississippi, only really excluding some southeastern counties. These frogs are usually brown with 2 rows of square/rectangular spots on the back. Males have paired vocal sacs and all adults will have bright yellow or orange on the inner thighs. Calls sound like “soft snores” that last for a couple of seconds (Powell et al., 2016).
