Kozlov's pygmy jerboa is a very small rodent with a relatively large head and a very long tail. The head and body measure 4.3–5.6cm and the tail 11.9–12.6cm, and it weighs 7–12g. The fur is silky, sandy-grey above with yellowish-grey hair bases, the flanks rather paler and the underparts white or yellowish. The scantily haired tail has a tufted, dark tip (Wikipedia, general species account).
It is found in north-western China and southern and eastern Mongolia, in temperate desert. It lives in a burrow and is mainly nocturnal, emerging at dusk to feed on seeds, green plant matter, spiders and insects. Breeding takes place in April and May, with litters averaging three to five young (Wikipedia, general species account).
