DEEC has had a resident groundhog this summer. While groundhogs are fairly common, this one is worth noting because of its unique color: black.
Its black fur is due to excess amounts of melanin, a pigment that gives skin, hair, feathers and fur their dark color. This occurrence is known as melanism, while the opposite is albinism, which occurs because of a lack of melanin or other types of pigment.
