Pygmy Hedgehog Tenrec, Lesser Hedgehog
Tenrec (Echinaps telfairi)




Family: Tenrecidae Status: Not available.

Range: Southwestern and west coastal areas of Madagascar.

Habitat: Semi-desert, thorny brush country and other dry areas.
Diet: Wild: Invertebrates and small vertebrates. Captivity: Dry cat food.
Description: Body length is 5-7”, with a weight of 6-7 oz. Although they are primitive animals, tenrecs have all the morphological characteristics and modes of reproduction found in higher mammals. External sex organs are alike in males and females. The rectum and urogenital tract open into a common cloacal-like skin fold. The legs are short; the tail is short, flattened, broad, and spine covered as is the rest of the dorsal side of the body. The spines, however, are not barbed as the spines found on porcupines. The fur is brown above, whitish below, with a whitish cast where spines are present. Eyes and external ears are bigger than in other tenrecs. The feet are five toed, with claws adapted for digging. The nose is extended, but not to the trunk-like extent found in other tenrecs. Females have five pairs of mammary glands.
Lifespan: 3-4 years.
Reproduction: Tenrecs achieve sexual maturity between 1-1½ years of age. Females will give birth to 2-10 offspring in nests constructed in burrows. When sexually excited, the males secrete a white, milky substance from their hardian glands, located in the corner of their eye.
Behavior: The lesser hedgehog tenrec is nocturnal, found sleeping in the heat of the day in small groups under boulders, tree roots, and in tree holes close to the ground. They roll into protective balls while sleeping or threatened. Insects are stalked using sight and sound, sniffing with outstretched nose until they are very close. The catch is made with a quick forward thrust of the mouth. Agile climbers, tenrecs can rest in forks of trees. They frequently groom their faces with spread toes on both forepaws. During Madagascar’s dry winter when food is scarce, tenrecs go into torpor – eyes closed, they roll into balls with their noses between their forepaws. They are cold to the touch and breath once every three minutes. If touched they snort, grunt, and snap at the intruder. During torpor they forego food and water, cease defecating and remain fat. Tenrecs can freeze to death at temperatures below 62 degrees Fahrenheit. When active at temperatures in the mid-60’s, tenrecs raise their body temperature through constant motion. They use shelters for resting when temperatures are also in this range.
Our animals: One male born in 08/06; two females born 12/93 and 7/96. All were donated from Topeka Zoo in July 2000. One unknown born 08/07.
