The long-nosed potoroo exhibits many morphological specializations such as an elongated pointed rostral region (nose), erect ears, large eyes, claws for digging, and long robust hind legs. [5] It is only a small marsupial, with a body length between 34 and 38 cm (13–15 in), and a semi-prehensile tail length of 15 to 24 cm (5.9–9.4 in).
The short-tailed bandicoot rat is a nocturnal rodent and spends most of its time in a burrow which comprises many tunnels and chambers. The depths may be up to 60 cm and the burrow may be up to 9 m long, covering an area of up to 120 m 2. One chamber is lined with vegetation for nesting.

Jerboas have metatarsal bones that are fused into one long bone, called the cannon bone. Their cannon bone is more distinct and defined than in other rodents. [3] This acts as leverage to allow them to reach higher heights while jumping, while also supporting the legs. Their back legs are often up to four times as long as the front legs.
