In terrestrial vertebrates, digitigrade (/ ˈ d ɪ dʒ ɪ t ɪ ˌ ɡ r eɪ d /) [1] locomotion is walking or running on the toes (from the Latin digitus, 'finger', and gradior, 'walk').A digitigrade animal is one that stands or walks with its toes (phalanges) on the ground, and the rest of its foot lifted.
A closeup of a rat tail. The characteristic long tail of most rodents is a feature that has been extensively studied in various rat species models, which suggest three primary functions of this structure: thermoregulation, [13] minor proprioception, and a nocifensive-mediated degloving response.

The hind limb and foot of the elephant are oriented semi-plantigrade, and closely resemble the structure and function of the human foot. The tarsals and metapodials are arranged so as to form an arch, similarly to the human foot. The six toes of each foot of the elephant are enclosed in a flexible sheath of skin.
Plantigrade foot occurs normally in humans in static postures of standing and sitting. It should also occur normally in gait (walking). Hypertonicity , spasticity , clonus , limited range of motion, abnormal flexion neural pattern, and a plantar flexor (calf) muscle contracture, as well as some forms of footwear such as high heeled shoes may ...
Pes of a rodent, Eurasian hamster Cricetus cricetus. The pes (Latin for foot) is the zoological term for the distal portion of the hind limb of tetrapod animals. [1] It is the part of the pentadactyl limb that includes the metatarsals and digits ().

Anatomy of the wood rat's forelimb (lateral aspect) Bushy-tailed woodrats can be identified by their large, rounded ears, and their long, bushy tails. They are usually brown, peppered with black hairs above with white undersides and feet. The top coloration may vary from buff to almost black.
The naked mole-rat exhibits a highly unusual set of physiological and behavioral traits that allow it to thrive in a harsh underground environment; most notably its being the only mammalian thermoconformer with an almost entirely ectothermic (cold-blooded) form of body temperature regulation, [8] as well as exhibiting a complex social structure ...
