Lowland Streaked Tenrec (Hemicentetes semispinosus)
…is a small species of tenrec found throughout eastern and northern Madagascar. Like other tenrec species the lowland streaked tenrec is mostly nocturnal hunting for earthworms and insects under the cover of darkness. When threatened this tenrec can erect its quills forward and will attempt to drive them into its attacker. When foraging the lowland streaked tenrec is often found in small family groups that communicate with each other by vibrating the spines on their middle of their backs. They are the only recorded mammal to communicate via this method known as stridulation.
