The tropical pocket gopher (Geomys tropicalis) is a species of rodent in the family Geomyidae. It is endemic to Mexico. Its natural habitat is hot deserts. It is threatened by habitat loss.
The tropical pocket gopher is cinnamon to brown on its back and head. Its underparts have white fur, and its tail is mostly naked. They have large front feet, along with small eyes and a thick body. [2] Males are on average larger than females. [3]
The distribution of the tropical pocket gopher is restricted to a small area of the Veracruz moist forests, near the southeastern corner of Tamaulipas, Mexico. [4]
The tropical pocket gopher has a diploid number of 38. This is low compared to similar species. This could help them adapt to their restricted habitat. Since their numbers are low there is a high risk of them losing too much genetic variability to survive. [5]
The Caribbean monk seal, also known as the West Indian seal or sea wolf, was a species of seal native to the Caribbean which is now believed to be extinct. The main natural predators of Caribbean monk seals were large sharks, such as great whites and tiger sharks, and possibly transient orcas ; however, humans would become their most lethal enemy. Overhunting of the monk seals for oil and meat, as well as overfishing of their natural prey, are the likely reasons for the seals' extinction.
Pocket gophers, commonly referred to simply as gophers, are burrowing rodents of the family Geomyidae. The roughly 41 species are all endemic to North and Central America. They are commonly known for their extensive tunneling activities and their ability to destroy farms and gardens.
The yellow-faced pocket gopher is a species of pocket gopher that is native to shortgrass prairies in the south-western United States and northern Mexico. It is the species that lives north of the Southern Coahuila Filter-Barrier (SCFB). Among the different species, the yellow-faced pocket gopher has a small to medium-sized skull. The fossil of this genus was recorded from the pre-Pleistocene Benson Beds of Arizona.
The southeastern pocket gopher is a species of pocket gopher that is native to the southeastern United States. It occurs in Alabama, Georgia, and Florida, where it is the only pocket gopher.
The hispid pocket mouse is a large pocket mouse native to the Great Plains region of North America. It is a member of the genus Chaetodipus.
The genus Geomys contains 12 species of pocket gophers often collectively referred to as the eastern pocket gophers. Like all pocket gophers, members of this genus are fossorial herbivores.
Villa's gray shrew is a shrew native to northeastern Mexico, where it is called musaraña.
The desert pocket gopher is a species of rodent in the family Geomyidae. It is found in the state of Chihuahua in Mexico and in Texas and New Mexico in the United States.
The plains pocket gopher is one of 35 species of pocket gophers, so named in reference to their externally located, fur-lined cheek pouches. They are burrowing animals, found in grasslands and agricultural land across the Great Plains of North America, from Manitoba to Texas. Pocket gophers are the most highly fossorial rodents found in North America.
The Texas pocket gopher is a species of rodent in the family Geomyidae. It is found in Tamaulipas in Mexico and in Texas in the United States.
The central Texas pocket gopher or Llano pocket gopher is a species of rodent in the family Geomyidae. It is endemic to central Texas in the United States.
Buller's pocket gopher is a species of gopher that is endemic to Mexico.
The camas pocket gopher, also known as the camas rat or Willamette Valley gopher, is a rodent, the largest member in the genus Thomomys, of the family Geomyidae. First described in 1829, it is endemic to the Willamette Valley of northwestern Oregon in the United States. The herbivorous gopher forages for vegetable and plant matter, which it collects in large, fur-lined, external cheek pouches. Surplus food is hoarded in an extensive system of tunnels. The dull-brown-to-lead-gray coat changes color and texture over the year. The mammal's characteristically large, protuberant incisors are well adapted for use in tunnel construction, particularly in the hard clay soils of the Willamette Valley. The gophers make chattering sounds with their teeth; males and females make purring sounds when they are together, and the young make twittering sounds. Born toothless, blind and hairless, the young grow rapidly before being weaned at about six weeks of age.
The southern pocket gopher is a species of rodent in the family Geomyidae. It is found in Mexico and the United States, usually in high altitude grassland and shrubland. It feeds on plant material and has an extensive burrow above which is a large heap of earth on the surface of the ground.
The Michoacan pocket gopher is a species of rodent in the family Geomyidae. It is monotypic within the genus Zygogeomys. It is endemic to Mexico where its natural habitat is temperate, high-altitude forests. Its numbers are declining and it is listed by the IUCN as "endangered".
Baird's pocket gopher or the Louisiana pocket gopher is a species of pocket gopher that is native to the southern United States. In total, there are three almost identical species of eastern pocket gopher; Geomys attwateri, G. bursarius, and G. breviceps. G. breviceps is larger in size, G. attwateri is medium-sized and G. bursarius is a bit smaller. Other than by size variation they are not identifiable by external features. Baird's pocket gophers are small rodents with most of their weight on the top half of their bodies.
Knox Jones's pocket gopher is a species of pocket gopher found in Texas and New Mexico. This species is named for Dr. J. Knox Jones Jr. (1929–1992), a prolific mammalogist at Texas Tech University.
Geomys streckeri, also known as Strecker's pocket gopher, is a species of pocket gopher found in Texas. It was formerly considered a subspecies of the Texas pocket gopher. Chromosomal analyses have proven this species to be distinct. Analysis of its mitochondrial cytochrome b points to this species being a sister clade to Geomys personatus, Geomys attwateri, and Geomys tropicalis. Other evidence, using a Bayesian analysis of ribosomal RNA and certain proteins, points to it being embedded within the G. personatus clade and being a sister species to G. attwateri.
