The lowland streaked tenrec (Hemicentetes semispinosus ) is a small tenrec found in Madagascar. It belongs to the family Tenrecidae in the order Afrosoricida, and more specifically to the subfamily of the spiny tenrecs Tenrecinae. Its natural habitats are in tropical lowland rain forests in northern and eastern parts of Madagascar.

Appearance

Lowland streaked tenrecs are small insectivorous mammals from Madagascar. Their snouts are long and pointed, while the coat exhibits spines. They are distinguished by two main features: the first is a rather long, black-colored nose and the other feature is a black-colored coat, displaying yellow stripes and bright yellow spine crests, located over the top of their head and acts as a mean of self-defense against predators.

Habits and Lifestyle

The Lowland streaked tenrec is the only sociable tenrec species, gathering into groups. Groups of these animals are family units, consisting of up to 20 animals. They are diurnal creatures and can forage both solitarily and in small groups. They can be found on land, splashing in shallow waters, or digging underground. During the winter months (May-October) they conserve heat by reducing their body temperature to that of the air, meanwhile remaining active. However, when it gets too cold, tenrecs usually undergo periods of torpor. Nesting sites of lowland tenrecs are located near water, in fixed burrows. Their latrine sites are hidden in leaves and are typically situated near the entrance of the nest. Members of a group dig burrows, which are connected to each other, forming a complex burrow system, belonging to one group. Group members communicate through stridulating special quills. When threatened, tenrecs raise the quills, surrounding their neck. If threatened, they usually try to prickle the opponent with their quills, accompanying it with violent bucking of their head.

Seasonal behavior

Diet and Nutrition

Lowland streaked tenrecs are carnivorous (vermivorous or worm-eating) animals. They primarily feed on earthworms and supplement their diet with various insects.

Mating Habits

REPRODUCTION SEASON
September-December
PREGNANCY DURATION
55-63 days
BABY CARRYING
2-11 babies
INDEPENDENT AGE

BABY NAME
baby tenrec

Little is known about the reproductive system of this species. It's known that, during the mating season, males compete with each other, engaging in fights in order to attract the attention of receptive females. Lowland tenrecs mate in September-December. The gestation period lasts for 55-63 days, yielding 2-11 young with an average of 5-8 per litter. Male Lowland tenrecs are careful to young. Weaning occurs at 18-25 days old. Females of this species reach reproductive maturity as early as 25 days old, being the only tenrecs that begin breeding during the same season in which they were born.

Population

Population threats

Along with many other animals in Madagascar, these tenrecs are primarily threatened by the loss of their natural habitat as a result of continuous deforestation. In addition, this species is hunted for food.

Population number

According to IUCN, the Lowland streaked tenrec is very abundant and widespread throughout its range but no overall population estimate is available. Currently, this species is classified as Least Concern (LC) on the IUCN Red List.

Ecological niche

Feeding upon worms, Lowland streaked tenrecs control populations of these invertebrates, thus playing an important role in the ecosystem of their habitat.

Fun Facts for Kids

  • When spotting a predator, these animals emit ‘crunch’ and ‘putt-putt’ sounds, while the long hairs on their back become stiff, raising and prickling the opponent. And when the predator retreats, the tenrec takes its chance to quickly flee.
  • Newborn Lowland tenrecs lack spines, starting to develop them during the first day after birth.
  • The streaked tenrec is the only mammal species, practicing stridulation - this is when an animal rubs together parts of its body to give out a sound. This technique is more common for insects and snakes. For example, when a baby tenrec loses its mother, it will rub its spines together, emitting a specific noise, which will help the young find its mother.
  • Along with stridulation, these animals communicate through tongue-clicking to turn away intruders. It's also possible that they use echolocation, but this supposition is not proven yet.
  • When someone touches the Lowland streaked tenrec, this animal can slightly bounce, thrusting its quills into the intruder.
  • As opposed to the sharp and solid quills on the back, the underbelly of this animal is very soft.
  • Yellow quills on the Lowland streaked tenrec's head form a crown. In order to turn away intruders, the animal raises its quills. When threatened, it fiercely attacks the opponent with its head-butt.
  • This species is closely related to the highland streaked tenrec, inhabiting the central upland parts of Madagascar.
