The southern grasshopper mouse or scorpion mouse (Onychomys torridus) is a species of predatory rodent in the family Cricetidae, [2] native to Mexico and the states of Arizona, California, Nevada, New Mexico, and Utah in the United States. [1] Notable for its resistance to venom, it routinely preys on the highly venomous Arizona bark scorpion.
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 (e.g., dipodids and hopping mice).
The three species in this genus of New World mice are only distantly related to the common house mouse, Mus musculus.They are endemic to the United States and Mexico. The southern grasshopper mouse has around a 3.5 to 5.0 inches (8.9–12.7 cm) long body and a tail that is generally 1.0 to 2.5 inches (2.5–6.4 cm) long. [2]
The pale kangaroo mouse burrows only in fine sand, while the dark kangaroo mouse prefers fine, gravelly soils but may also burrow in sand or sandy soil. Kangaroo mice are nocturnal, and are most active in the two hours following sunset. They are believed to hibernate during cold weather. Although mitochondrial data indicate that the clades ...
[78] [79] Other predators adapted for hunting scorpions include the grasshopper mouse and desert long-eared bat, which are also immune to their venom. [80] [81] In one study, 70% of the latter's droppings contained scorpion fragments. [81] Scorpions host parasites including mites, scuttle flies, nematodes and some bacteria.
They range in size from the musky rat-kangaroo, at 20 cm (8 in) plus a 6 cm (2 in) tail, to the red kangaroo, at 160 cm (63 in) plus a 120 cm (47 in) tail. Macropodiformes primarily eat leaves, grass, ferns, and shrubs, as well as fruit and other plant material.
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 .
Phillips's kangaroo rat (Dipodomys phillipsii) is a species of rodent in the family Heteromyidae. [3] It is endemic to Mexico.Its natural habitat is hot deserts. The species is named after John Phillips, an official of a Mexican mining company who sent zoological specimens, including the type specimen of this kangaroo rat, to the British Museum.
