Identification. The Common Opossum is identified by its shaggy gray guard hairs and its pale underfur. Its cheeks are a dirty yellow color and its whiskers are black. The tail is black and white, the white portion often being longer than the black. The Virginia Opossum ( Didelphis virginiana (Kerr, 1792) looks very similar to D. marsupialis but is not present in the southern portion of Costa Rica ( Wainwright and Arias 2007).
