The barbary striped grass mice are found from sea level up to 1000 m. They mainly live in Mediterranean scrublands and woodlands and prefer areas with thick grass and herbaceous ground cover. However, this species has been reported from various nonforested, relatively dry habits along the coastal region of Northwest Africa. In general, barbary striped grass mice can be found in rocky outcrops in vegetated coastal dunes, juniper scrub, argon sage grassland, and argon savanna throughout their geographic range.

pelage is brown or oatmeal-colored and has a single dark vertebral stripe, extending from the middle crown to the rump. Flanking this vertebral line on each side are 4 to 5 primary pairs of bold alternating light and dark stripes, and dark stripes are usually wider than the corresponding light stripes. Additionally, the pelage features secondary light lines, particularly evident within the first primary dark stripes. The ventral pelage is white. has a narrow and pointed head, usually of the same color as the dorsum. Its ears are large and rounded, covered with hair. (Carleton and Van Der Straeten, 1997; Happold, 1987; Kingdon, 1984; Lahmam, et al., 2008; Shortridge, 1934; Stitou, et al., 1997; "Barbary Striped Grass Mouse (Lemniscomys barbarus)", 2011; "Mouse, Zebra (Lemniscomys barbarus)", 2007; van der Straeten, 2008)is the smallest of member of its genus, with masses ranging from 22 g to 48 g and an average mass of 30 g. Individuals range in body length from 8 to 12 cm and a tail ranging from 10 to 15 cm in length. This species is easily recognized due to its unique pelage, which includes a middorsal longitudinal stripes. The dorsal
molars are rooted, strongly lophodont, and appear similar to those of Lemniscomys griselda. The third molar is always smaller than the first and second molars. The skull of is especially robust when compared to congeners. In contrast to other members of g. Lemniscomys, the barbary striped grass mouse has inflated ectotympanic bullae, and similar to other murines, lacks a sphenofrontal foramen and squamosoalisphenoid groove. Sexual dimorphism has not been reported in this species. is diploid and has 54 chromosomes.

Male barbary striped grass mice reach sexual maturity at about 10 weeks, while females may take several months longer and may not reproduce up to a year later. Mating season occurs during the warm, wet spring and summer months, with no reproductive activity reported during winter. It has been suggested that reproduction is correlated with season and ambient temperature. Gestation lasts for 21 days, and the average litters consist of 5.5 pups. While the reproductive behavior of this species has not been described in detail, new-borns of the closely related Lemniscomys striatus weigh 3 grams at birth and are covered in short hair. Dorsal stripes are present at birth. Their eyes open around one week after birth, and adult weight is not achieved until 5 months old. Mean birth mass at birth for Lemniscomys rosalia pups, another close relative, is 2.6 grams. Pups are altricial at birth and have fused toes, closed eyes, and folded ear flaps. Young develop quickly, opening their eyes by 9 to 11 after birth and becoming fully furred by day 18.

Lemniscomys griselda, burrows are occupied by a solitary individual, a breeding pair, and possibly their young. The nests of L. griselda are excavated in areas with dense grass cover. There are well-developed runways between burrows and feeding grounds. feeds mostly during the evening and early morning. Due to its extensive runway system, is rarely found far from its burrow. (Kingdon, 1984; Lahmam, et al., 2008; Shortridge, 1934; Smithers, 1983; van der Straeten, 2008)is a very active, diurnal rodent. Some reports indicate that captive individuals can be crepuscular or exhibit irregular nighttime activity. While small groups can sometimes be found during feeding bouts, does not appear to be highly social. THis species lives in grass burrows or nests, which typically have single, relatively large entrance. In the closely related
Communication and Perception
Consistent with the diurnal activity patterns of this species, (Bobu, et al., 2008)'s eyes contain a relatively large number of cones, the photoreceptors responsible for color vision, in their retinas. Cone-rich retinal structures are relatively rare among contemporary mammalian species. As most mammals are nocturnal, they have rod-dominated retinas. No other information exists regarding communication and perception in this species. uses scent marks to demarcate territories and communicate with conspecifics, especially during mating season.

Diurnal birds of prey such as hawks (Accipitridae and secretary birds (Sagittarius serpentarius reportedly prey on . Other predators include genets, mongooses, jackals, small cats, cheetahs, and snakes. To avoid predation, when threatened hurriedly escapes to its burrow. The striped pattern on its dorsal pelage may help camouflage from potential predators and its burrowing nature likely helps minimize risk of predation as well.

The complicated taxonomy of Lemniscomys zebra, on the basis of multivariate morphometrics of skull measurements. They described the former as a species restricted to shrub vegetation along a narrow coastal strip in Morocco, Algeria, and Tunisia, while the latter has a wide-ranging sub-Saharan distribution. This reclassification addressed substantial variation that was apparent within . However, more work needs to be done on Lemniscomys zebra, which remains a highly variable taxon. (Carleton and Van Der Straeten, 1997)has received much attention over the years, leading to a number of reclassificatons. Of particular importance is Carleton and Van der Straeten (1997), who recently split into two species, and

Found in coastal areas between 30 and 40 degrees latitude, in areas with a Mediterranean climate. Vegetation is dominated by stands of dense, spiny shrubs with tough (hard or waxy) evergreen leaves. May be maintained by periodic fire. In South America it includes the scrub ecotone between forest and paramo.

active at dawn and dusk
having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect.
- desert or dunes
in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
