  2. 02Handle frogs only with wet hands, free of sunscreen or bug spray — their skin absorbs chemicals.

Conservation status

IUCN Red List
Least ConcernLC

Least Concern and native to the East — but invasive in the western US and many countries, where it eats native frogs.

What Least Concern means

Assessed as widespread and abundant. This describes the global population, not fishing pressure or legal protection.

On your plate

Not Typically Eaten

Frog legs are eaten, and Pennsylvania allows a licensed harvest in season. TIDE doesn't show recipes for wild amphibians.

Conservation status and seafood sustainability are two different questions. A species can be Least Concern globally and still be overfished, protected or unsustainable where you are.

Native to eastern North America; introduced around the world
