Pituophis catenifer is a species of nonvenomous colubrid snake endemic to North America. Six subspecies are currently recognized, including the nominotypical subspecies, Pituophis catenifer catenifer, described here. This snake is often mistaken for the prairie rattlesnake but can be easily distinguished from a rattlesnake by the lack of black and white banding on its tail, and by the shape of its head which is narrower than a rattlesnake's. less ↑

The California kingsnake (Lampropeltis getula californiae) is a nonvenomous colubrid snake endemic to the western United States and northern Mexico.

It is native to North America and introduced to Patagonia in South America and some European countries (e.g. Finland). In the United States and Canada, the species is often referred to simply as "beaver", though this causes some confusion because another distantly related rodent, Aplodontia rufa, is often called the "mountain beaver". Other vernacular names, including American beaver and less ↑

The coypu (from Spanish coipú, from Mapudungun koypu; Myocastor coypus), also known as the nutria, is a large, herbivorous, semiaquatic rodent. It has been classified for a long time as the only member of the family Myocastoridae. However, studies based on the comparison of DNA and protein sequences showed that Myocastor is nested within Echimyidae, the family of the spiny rats. Originally native to subtropical and temperate South America, it has since be less ↑

The muskrat (Ondatra zibethicus), the only species in genus Ondatra and tribe Ondatrini, is a medium-sized semiaquatic rodent native to North America and is an introduced species in parts of Europe, Asia, and South America.
