A cotton rat is any member of the rodent genus Sigmodon. Their name derives from their damaging effects on cotton as well as other plantation crops, such as sugarcane, corn, peanut and rice. Cotton rats have small ears and dark coats, and are found in North and South America. Members of this genus are distributed in the Southwestern United States, Mexico, Central America, and South American countries of: Venezuela, Ecuador, Colombia, Peru, Brazil, Guyana, and Suriname. Many of the species are found in Mexico.
The antelope jackrabbit is a species of North American hare found in southern Arizona and northwestern Mexico that occupies dry desert areas.
Allen's yellow bat is a species of vesper bat. There is some taxonomic debate surrounding this species, with some authors considering Baeodon a genus rather than a subgenus. It is endemic to Mexico.
Allen's woodrat is a species of rodent in the family Cricetidae.
Allen's hylomyscus or Allen's wood mouse is a species of rodent in the family Muridae. It is native to West and Central Africa, where it is widely distributed. It occurs in deciduous forest habitat.
The round-tailed muskrat is a species of rodent in the family Cricetidae, sometimes called the Florida water rat. The species is monotypic in the genus Neofiber. It is found only in the southeastern United States, where its natural habitat is swamps.
Transandinomys bolivaris, also known as the long-whiskered rice rat, is a rodent in the family Cricetidae. It is found in humid forest from northeastern Honduras to western Ecuador, up to 1,800 m (5,900 ft) above sea level. Since it was first described in 1901 from Ecuador, six scientific names have been introduced for it, but their common identity was not documented until 1998 and the species has long been known under the name Oryzomys bombycinus, described from Panama in 1912. The name Oryzomys bolivaris was used before it was moved to the new genus Transandinomys with Transandinomys talamancae in 2006.
The tawny-bellied cotton rat is a species of rodent in the family Cricetidae. It is found in Mexico and in the US states of Arizona and New Mexico.
The unexpected cotton rat is a species of rodent in the family Cricetidae. It is found only in Ecuador at elevations of 3500 to 4000 m, where it has been found in association with streams and marshes. It is also known as the Ecuadorian cotton rat.
The white-eared cotton rat is a species of rodent in the family Cricetidae. It is found only in Mexico.
The Jaliscan cotton rat or Mexican cotton rat is a species of rodent in the family Cricetidae. It is found only in Mexico. They commonly have brown fur with white fur on the belly. They are ground-dwelling and prefer open habitats.
The yellow-nosed cotton rat is a species of rodent in the family Cricetidae. It is native to Mexico and to the states of Arizona, New Mexico, and Texas in the United States, where it inhabits mountain grassland, scrub, and pinyon-juniper woodland.

The Toltec cotton rat is a rodent species in the family Cricetidae. It is found in eastern Mexico from the Rio Grande to the Yucatán Peninsula, as well as in Belize and northern Guatemala. It prefers moist grassland habitat. While long thought to be a subspecies of S. hispidus, recent taxonomic revisions, based on mitochondrial DNA sequence data, have split the extensive former species range into three separate species. Carroll et al. (2004) indicate that the southern edge of the S. hispidus distribution is likely near the Rio Grande where it meets the northern distribution of S. toltecus. The range of S. toltecus extends from northern Mexico south into Chiapas where it occurs in sympatry with S. hirsutus . Rats from this species group have been used as laboratory animals.
The southern cotton rat is a rodent species in the family Cricetidae. It is found from southern Chiapas in Mexico through Central America, except for Belize, and as far east as northern Colombia and Venezuela. It lives in tropical rainforest, dry forest and savanna, as well as in cultivated areas. The species is terrestrial and primarily diurnal. It was long thought to be a subspecies of S. hispidus. However, recent taxonomic revisions, based on mitochondrial DNA sequence data, have split the extensive former species range into three separate species. Carroll et al. (2004) indicate that the southern edge of the S. hispidus distribution is likely near the Rio Grande where it meets the northern distribution of S. toltecus. The range of S. toltecus extends from northern Mexico south into Chiapas where it occurs in sympatry with S. hirsutus . Rats from this species group have been used as laboratory animals.
The Miahuatlán cotton rat was formerly considered a rodent species in the family Cricetidae. It is found only on the Pacific slope of the Sierra de Miahuatlán in the Mexican state of Oaxaca, where it lives in deciduous tropical forest. The IUCN currently considers it to be conspecific with Sigmodon alleni.
The squirrel galagos are a group of four species of strepsirrhine primates. They are classified in the genus Sciurocheirus of the family Galagidae.
