BiologyAlthough its recent discovery means that little is known about the biology and ecology of the grey-faced elephant-shrew, it is likely to be similar to that of other species in the Macroscelididae family. It is known to be a strictly diurnal species (2), and like other elephant shrews, probably spends the majority of the day searching for invertebrate prey on the forest floor, probing the leaf litter with its long, flexible nose (4). It may also use its clawed forefeet to dig small holes in the soil to unearth food. All sengis have long tongues that can reach beyond the tip of their elongated noses, which are used to flick small prey into their mouths (4). Nests of the grey-faced elephant-shrew are oval cup-shaped structures, dug into the soil and lined with layers of leaves. Loose leaves are then piled on top to form a vague dome that blends into the thick leaf litter covering the forest floor. The nests of this species have been found at the base of trees (2). Like other sengis, the grey-faced elephant-shrew may be a monogamous species, giving birth to litters of one or two young (4).
