Heermann’s kangaroo rat (Dipodomys heermanni) 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.It is considered “broad-faced”, unlike many other species of kangaroo rats, which are considered to be “narrow-faced”. It has five toes on each hind foot, and this small characteristic is important in distinguishing it from similar species such as Dipodomys californicus and Dipodomys nitratoides. Additionally it is smaller than Dipodomys ingens, Dipodomys venustus, and Dipodomys elephantinus.Heermann’s kangaroo rat averages a total length of 250–313 mm (9.8–12.3 in), with their tail measuring 160–200 mm (6.3–7.9 in), their hind foot measuring 38–46 mm (1.5–1.8 in), and their ear measuring 10–17 mm (0.39–0.67 in). Additionally when looking at all standard external measurements it has been found they demonstrate significant sexual dimorphism.
