The streaked tenrec is the only mammal known to use stridulation for generating sound, a method more commonly associated with insects and snakes. [12] [13] Due to its rarity, there is not sufficient information regarding the functional-morphological mechanism of the streaked tenrec. The sounding quills are different from the spines and hair and ...
The highland streaked tenrec (Hemicentetes nigriceps) is an insectivore which lives in the central upland regions of Madagascar. Its black and white striped body is covered with quills, which it will raise when agitated. The spines detach and remain in the body of an inquisitive predator.
A tenrec (/ ˈ t ɛ n r ɛ k /) is a mammal belonging to any species within the afrotherian family Tenrecidae, which is endemic to Madagascar.

There are two species in the genus Hemicentetes, H. semispinosus and H. nigriceps both are found only on Madagascar.Lowland streaked tenrecs (H. semispinosus) are found in the rainforests on the east side of the island and highland streaked tenrecs (H. nigriceps) are found in humid forest and plateau savanna boundary habitat in the central upland portion of Madagascar.
As a rule, tenrecs and otter shrews tend to be small animals varying from 4 cm to 39 cm in length. There is no pronounced body type since they have evolved to occupy a number of small-bodied, faunivorous niches in Madagascar (tenrecines) and mainland Africa (potamogalines).
Tenrecinae is a tenrec subfamily endemic to the island of Madagascar. [1] It contains the largest species in the family, Tenrec ecaudatus. [2] All members of the genus possess spines, analogous to those of hedgehogs, for defense against predators.
Tenrecomorpha is the suborder of otter shrews and tenrecs, a group of afrotherian mammals indigenous to equatorial Africa and Madagascar, respectively. [2] [3] The two families are thought to have split about 47–53 million years ago.
