Lowland streaked tenrec

Hemicentetes semispinosus

The lowland streaked tenrec is a small tenrec found in Madagascar.
Lowland streaked tenrec, Andasibe, Madagascar Found at the start of a lengthy night hike in an Andasibe camp site. Allegedly they are rare to see in winter. This species is very easy to recognize from its yellow streaks. There's a lot of interesting morphological  facts regarding this species, but most are rather complex and technical. Therefore, I'll limit it to the most spectacular fact: this is the only mammal species known in the world that uses Stridulation for generating sounds. 

Stridulation is the production of sound by moving body parts together, common in insects and in some birds, yet this is the only mammal to do it. Specifically, this species rubs it spines together to produce a sound when threatened.

This species is also known for always having at least one obstructing element in front of its face, example from 4 years earlier:

Appearance

It is a small animal, with a long snout and limbs, and a vestigial tail. Pelage black with yellow longitudinal stripes dorsally, light beneath; scattered quills, some barbed and detachable.
Lowland streaked tenrec by day, Andasibe, Madagascar A chance wild encounter with this beautiful animal. Our guide spotted it and managed to corner it. In this shot, he's holding its hind legs. The release struggle made it very hard to take a sharp shot, this is the least awful one. 

Of course, it was released unharmed immediately afterwards. Africa,Andasibe,Hemicentetes semispinosus,Lowland streaked tenrec,Madagascar,Madagascar 2019,World

Distribution

The species is found in tropical lowland rain forest, in the northern and eastern parts of Madagascar.

Behavior

If threatened by a predator , a streaked tenrec erects the barbed quills on its back and on the crest around its head, pointing them completely forward, and drives them in to the attacker's nose or paws with body and head movements. The nonbarbed quills are clustered in the middle of the back, and produce a faint chattering sound when vibrated, and are used to communicate within family groups.
Lowland streaked tenrec in Maroantsetra, Madagascar Yes, I'm definitely cursing at that grass blocking its face, but this is the only photo I have of this species. We found it when returning from dinner and walking back to our lodge at the beach in Maroantsetra. They are quite active and fast and keep changing direction, making them hard to photograph. 

Tenrecs are a very interesting and diverse family of mammals of which most only occur in Madagascar, yet somehow their isolated evolution led to features we recognize in other places and species. This one has a lot in common with hedgehogs, for example.

Fun fact for this particular streaked tenrec species: it is the only mammal in the world known to produce sound by rubbing body parts together, a process called stridulation. They vibrate their quills to communicate with others.

One minute after this capture and only a few meters apart, we found the arch enemy of all tenrecs:

Habitat

The species is found in tropical lowland rain forest, in the northern and eastern parts of Madagascar.

Reproduction

Breeding takes place during October to December and possibly at other times, depending upon local food supply and temperature. The gestation period lasts 58 days, and the female gives birth to usually between 5 and 8 young. The young are weaned at 18 to 25 days.

Food

It is active during day and night, feeding primarily upon earthworms, but also on insects.
