The Virginia opossum (Didelphis virginiana), commonly known as the North American opossum, is the only marsupial, and therefore the only opossum, found north of Mexico, but its range extends south into Central America. In the United States, the animal is typically referred to simply as a possum (‘possum) or an opossum. It is a solitary and nocturnal animal about the size of a domestic cat, and a successful opportunist.

Opossums are familiar to many North Americans as they frequently inhabit settled areas due to the associated proximity to food sources, notably trash cans, as well as pet food, compost piles, gardens, rodents, etc. Their slow and nocturnal nature, and their attraction to roadside carrion, puts them in danger of becoming roadkill.
The Virginia opossum is the original animal named “opossum”, a word which comes from Algonquian wapathemwa, meaning “white animal”. Colloquially, the Virginia opossum is frequently just called a “possum”.[5] The name opossum is applied more generally to any of the other marsupials of the families Didelphidae and Caenolestidae. The generic name (Didelphis) is derived from Ancient Greek: di, “two”, and delphus, “womb”.[6]

The possums of Australia, whose name is derived from a similarity to the opossums of the Americas, are also marsupials, but of the order Diprotodontia.

The Virginia opossum is known in Mexico as tlacuache, tacuachi, and tlacuachi, from the Nahuatl word tlacuatzin.

The eastern copperhead (Agkistrodon contortrix)[3] also known as the copperhead is a species of venomous snake, a pit viper, endemic to Eastern North America; it is a member of the subfamily Crotalinae in the family Viperidae. Its generic name is derived from the Greek words ancistro (hooked) and odon (tooth), or fishhook.[4] The trivial name, or specific epithet, comes from the Latin contortus (twisted, intricate, complex); which is usually interpreted to reference the distorted pattern of darker bands across the snake’s back, which are broad at the lateral base but “pinched” into narrow hourglass shapes in the middle at the vertebral area.[5][6] Five subspecies have been recognized in the past,[7] but recent genetic analysis shows that A c. contorix and two of the subspecies are monotypic, while Agkistrodon laticinctus (formerly Agkistrodon contortrix laticinctus) and the fifth subspecies are a single distinct species (see subspecies table below).

It is a common species in many areas within its range, which may lead to accidental encounters with humans.
Eastern copperheads found in North America; its range within the United States is in Alabama, Arkansas, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Mississippi, Missouri, Nebraska, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia and West Virginia. In Mexico, it occurs in Chihuahua and Coahuila. The type locality is “Carolina”. Schmidt (1953) proposed the type locality be restricted to “Charleston, South Carolina”.[2]

Unlike some other species of North American pit vipers, such as the timber rattlesnake and massasauga, copperheads has mostly not re-established itself north of the terminal moraine after the last glacial period (the Wisconsin glaciation),[14] though it is found in southeastern New York and southern New England, north of the Wisconsin glaciation terminal moraine on Long Island.

Within its range, it occupies a variety of different habitats. In most of North America, it favors deciduous forest and mixed woodlands. It is often associated with rock outcroppings and ledges, but is also found in low-lying, swampy regions. During the winter, it hibernates in dens or limestone crevices, often together with timber rattlesnakes and black rat snakes.[15] In the states around the Gulf of Mexico, however, this species is also found in coniferous forest. In the Chihuahuan Desert of West Texas and northern Mexico, it occurs in riparian habitats, usually near permanent or semipermanent water and sometimes in dry arroyos (brooks).
