Question: is the difference between a hedgehog and a groundhog?
Answer: A Hedgehog , subfamily Erinacinae, is covered in short spines. It resembles an echidna or a little porcupine, though these animals are not related. A Groundhog is a totally different species, family Sciuridae, related to marmots and ground squirrels. They look a little like beavers or fat tree squirrels.
