Unusually for tenrecs, the lowland streaked tenrec is active both at night and during the day, and is the only species to form groups. It remains with its family, numbering up to 20 individuals in each burrow (2). They may forage together amongst the leaf litter for earthworms and other soft-bodied invertebrates, using their long snouts to delve into small spaces (5). During the winter (May to October), tenrecs can drop their body temperature to nearly that of the surroundings, but still remain active. This conserves energy, but in the coldest weather they must hibernate (6).
Nesting in burrows 1.5 metres long and 15 cm deep near a stream or water body, the lowland streaked tenrec covers the burrow entrance with leaves and often creates a latrine site nearby (3). Mating takes place between September and December, and young are born after a gestation of 55 – 63 days. The female gives birth to between two and eleven young, averaging six in each litter. Females are reproductively active at a young age, sometimes breeding at just five weeks (2).
Mothers and young communicate by stridulating – they vibrate specialized quills on their mid-dorsal region creating a low-pitched noise. These tenrecs also make ‘crunch’ and ‘putt-putt’ sounds, particularly when agitated. If threatened, this species will raise the spines around the neck and buck the head violently to attempt to lodge the barbed spines into the attacker (3).
