Dipodomys heermanni morroensis (Merriam, 1907) |
The Morro Bay kangaroo rat(Dipodomys heermanni morroensis), is an endagered rodent in the Heteromyidae family and endemic to San Luis Obispo County, California. The species is the smallest subspecies of the Heermann's kangaroo.
The Heermann's kangaroo rat (Dipodomys heermanni) is found in warm and semi desert areas. The Morro Bay kangaroo rat (D. h. morroensis) subspecies is unique to Baywood fine sands, a soil type found in Morro Bay, Los Osos, and Montana de Oro State Park on the Central Coast of California. As a result, the Morror Bay kangaroo rat lives in a restricted 2 km area south of Morro Bay in San Luis Obispo County, California.
The burrows of the Morro Bay kangaroo rat enter the ground at an angle.
Like gerbils and pyramid rats, the Morro Bay kangaroo rats resemble little kangaroos, with well-developed hind limbs for jumping, short front limbs, and a long tail used for balance while leaping. Their ears are average in size and the hair on their backs varies between brown and yellow, while the hair on their bellies is white. As nocturnal animals, their eyes are very large. The Morro Bay kangaroo rat is 11 to 13 cm long and its tail measures between 16 and 19 cm. It weighs between 60 and 80 g.
The Morro Bay subspecies is the smallest of all subspecies. The male is measured to be 300.4 mm while the females are about 295.1 mm long.
The primary food of Morro Bay kangaroo rats is seeds.
They have 2 to 3 litters a year. The amount of pups in the litter ranges from one to seven with the average being two. They are born with no hair, eyes, ears closed, and toothless.
The Morro Bay kangaroo rat is federally endangered. [1] As of 2023, despite numerous localized and range-wide surveys, the animal has not been detected by any of these analyses and has remained unseen since 1986. [2]
Kangaroo rats, small mostly nocturnal rodents of genus Dipodomys, are native to arid areas of western North America. The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, but developed this mode of locomotion independently, like several other clades of rodents.
The giant kangaroo rat is an endangered species of heteromyid rodent endemic to California.
Heteromyidae is a family of rodents consisting of kangaroo rats, kangaroo mice, pocket mice and spiny pocket mice. Most heteromyids live in complex burrows within the deserts and grasslands of western North America, though species within the genus Heteromys are also found in forests and their range extends as far south as northern South America. They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches to their burrows.
Dipodomyinae is a subfamily of heteromyid rodents, the kangaroo rats and mice. Dipodomyines, as implied by both their common and scientific names, are bipedal; they also jump exceptionally well. Kangaroo rats and mice are native to desert and semidesert ecosystems of western North America from southern Canada to central Mexico. They are generally herbivorous foragers, and dig and live in burrows.
Estero Bay is a bay located on the Pacific Coast in San Luis Obispo County, central California. It is about 15 miles (24 km) from its south end at Point Buchon/Montana de Oro State Park, to its north end at Point Estero, which is about 5 miles (8 km) northwest of Cayucos. It is indented about 5 miles (8 km) into the California coast.
Ord's kangaroo rat is a kangaroo rat native to western North America, specifically the Great Plains and the Great Basin, with its range extending from extreme southern Canada to central Mexico.
The California kangaroo rat is a species of rodent in the family Heteromyidae. However, populations are declining, having not fully recovered after the drought in California from 2013 to 2015 destroyed their habitat and changed it into desert.
The Gulf Coast kangaroo rat is a species of rodent in the family Heteromyidae found in Mexico and the state of Texas in the United States. Its appearance and ecology are very similar to those of its putative sister species, Ord's kangaroo rat.
The San Quintin kangaroo rat is a species of rodent in the family Heteromyidae. It is endemic to Mexico, where it is known only from western Baja California. Its natural habitat includes arid lowlands with sparse vegetation.
Heermann's kangaroo rat is a species of rodent in the family Heteromyidae. Their long smooth pelage resembles typical kangaroo rats, with their dorsal side showing a mixed range of olive, black and orange colors. There are 9 distinguished sub-species of Dipodomys heermanni: D.h. arenae, D.h. berkeleyensis, D.h. dixoni, D.h. goldmani, D.h. heermanni, D.h. jolonensis, D.h.morroensis, D.h. swarthi, and D.h. tularensis. The dental formula of Dipodomys heermanni is 1.0.1.31.0.1.3 × 2 = 20.
The San José Island kangaroo rat is a subspecies of rodent in the family Heteromyidae. It is endemic to Mexico, where it is found only on San José Island off the east coast of Baja California Sur. is restricted to an area of only 30 km2 in the southwestern coast of San José Island, Lower California, with the population having been drastically reduced in size and being close to extinction No other species of Dipodomys occur in sympatry with D. insularis.
Merriam's kangaroo rat is a species of rodent in the family Heteromyidae. The species name commemorates Clinton Hart Merriam. It is found in the Upper and Lower Sonoran life zones of the southwestern United States, Baja California, and northern Mexico.
The Fresno kangaroo rat or San Joaquin kangaroo rat is a species of rodent in the family Heteromyidae. It is endemic to areas within and near the San Joaquin Valley of California in the United States. Habitat destruction due to agricultural development and urbanization has put this species at risk, and the International Union for Conservation of Nature has assessed its conservation status as "vulnerable".
The Panamint kangaroo rat is a species of rodent in the family Heteromyidae. It is endemic to the Mojave Desert in eastern California and western Nevada, in the United States.
The banner-tailed kangaroo rat is a species of rodent in the family Heteromyidae. It is found in arid environments in the southwestern United States and Mexico where it lives in a burrow by day and forages for seeds and plant matter by night.
The silky pocket mouse is a species of rodent in the family Heteromyidae. It is found in northern and central Mexico and the southwest region of the United States. It is a species of least concern, according to the IUCN, with no known major threats. The silky pocket mouse eats seeds, succulent parts of plants and nuts, and carries food in its cheek pouches. It lives in low valley bottoms with soft soils, among weeds and shrubs, where it burrows in the sand to bury seed caches. The species is more tolerant of harsh habitat conditions than other pocket mice.
