Of the stripes found on the body, two are found down the middle of the sides and the third is found down the middle of the dorsum. One of these yellow stripes is found down the median of the rostrum and the other three are found on the body. semispinosus) have black and yellow quills covering their bodies and have four primary longitudinal yellow stripes. Perception Channels: visual tactile ultrasound chemical Scent-marking has also been observed to mark territories in some individuals.Ĭommunication Channels: tactile acoustic chemical Chattering and/or squeaking sounds are emitted when the animal is disturbed which sometimes occurs with a low buzzing which happens when quills begin to rise as a reaction to being upset. Tongue clicks are used as well and may be a possible means of echolocation, but further studies should be conducted to see whether or not true echolocation is used. These sounds might also be used as a predator warning device. When the tips of these spines are rubbed together rapidly they produce high-frequency sounds that are thought to allow communication between members of foraging groups. When introduced to a new location, streaked tenrecs repeatedly use an explicit area as a latrine and will sometimes mark new burrows with feces.Ī stridulation organ consisting of 7 to 16 specialized spines is found in both species ( H. Nose-touching is a common mode of interaction between individuals. Females also are non-aggressive and usually just try to avoid each other. Head-butting is extremely useful during scuffles over mates due to an enlarged frontalis muscle on the forehead that increases mobility of the facial spines. Males may fight over females by biting each other, head-butting, or grappling, but they are generally docile. If a disturbance continues, stamping of the forefeet may occur as well as rushing at the disturbance even bright light has been known to bring on these reactions. This is how an animal can impale a potential enemy or predator with quills. These tenrecs erect spines on the head while moving the head up and down repetitively if the animal is disturbed.
