Sengis are monogamous and mate for life (3). Pairs occupy home ranges, which they defend against intruders although individuals spend the majority of their time alone within this area (4). They are diurnal, spending the night asleep in a nest constructed from leaf litter on the forest floor; carefully choosing from about six nests to ensure they remain undetected by predators (4). Mating occurs throughout the year and females give birth to a single young after a gestation period of around 42 days (3). After 2 weeks the young are fully weaned and will emerge from the nest to forage with their mother, although they are completely independent after a mere 5 days following emergence (3). These sengis forage for invertebrates such as earthworms, millipedes, insects and spiders by searching through the leaf litter on the forest floor with their flexible nose (3). These small mammals must be constantly vigilant of predators such as harrier eagles (Circus sp.), and snakes, including black mambas (Dendroaspis polylepis) and forest cobras (Naja melanoleuca), and can run at speeds of up to 25 km per hour when trying to escape (4). Elephant-shrews will alert predators that they have been spotted and their cover blown by loudly slapping their tail on the forest floor (4).
