Tenrecs

Applies to most species in this group. Habitat: Madagascar forest and scrub. Individual species can differ, so compare with the species numbers above and the linked sources.

Housing & setup

Warm enclosures with climbing branches (hedgehog tenrecs) and hides; many go torpid in cooler months.

Diet

For Echinops telfairi, Smithsonian uses dry insectivore food with insects. A complete species-appropriate formulated diet should not be reduced to a small optional addition.

Health watch

Obesity; torpor can be mistaken for illness.

Understanding the animal

About this animal

It is the only species in the genus Echinops and is named in honour of Charles Telfair. It is endemic to Madagascar.

In the wild

Researched for this exact species, not its family. Good care copies these conditions.¹²³

Where it lives	Native to southern and southwestern Madagascar, using dry forest, scrub, coastal and semi-desert habitats. Rests in tree hollows, dead trees and beneath leaf litter, and regularly climbs.
Ground it lives on	leaf litter and sheltered soil under woody debris; also uses tree hollows
Climate	Seasonally warm and wet summers alternate with cooler, drier austral winters. Natural shelters expose animals to fluctuating temperatures; reliable measured wild temperature and relative humidity ranges were not established.
Active	Nocturnal, with daily torpor and several months of winter hibernation.
Social life	Primarily solitary.
Wild diet	Insects and their larvae, spiders and eggs; occasionally fruit.
Behavior to plan for	Climbs using hooked claws and curls into a spiny ball defensively. Its body temperature and activity can fall markedly during torpor.

What this means for care

Provide climbing structure and protected nest cavities as well as floor space.
Allow for seasonal appetite and activity changes rather than assuming constant mammalian activity.
Offer privacy during daytime rest and avoid forcing a curled animal open.

Native climate (measured)

Warm-season highs	about 93°F (up to 94°F in the hottest sampled areas)
Cool-season lows	about 55°F (down to 53°F in the coldest sampled areas)
Average temperature	76–77°F across sampled records
Relative humidity	69–69% on average (driest month about 66%)
Rainfall	about 575 mm a year, with strong wet and dry seasons

Measured at 84 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.

From the sources

Overview	The lesser hedgehog tenrec (Echinops telfairi) is a species of mammal in the family Tenrecidae. It is the only species in the genus Echinops and is named in honour of Charles Telfair. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests, shrubland, and shrubland and dry savanna. — Wikipedia (community-edited)
Behavior	This tenrec is terrestrial. It spends its daytime hours resting under a log, a pile of branches, leaves, straws or in a hollow tree, although trees are widely scattered in its native habitat. In hot weather, it sleeps with its body extended, but otherwise lies in a curled position to rest. — Wikipedia (community-edited)
Appearance and size	The lesser hedgehog tenrec is a small, stout-bodied animal visually similar to a hedgehog, hence the name. Their tails are short, their limbs and muzzles are of moderate length, and their ears are prominent. The entire dorsum is covered with sharp spines. — Wikipedia (community-edited)

Data and studies

Researched care notes

Findings checked against veterinary, zoo, welfare, keeper and peer-reviewed sources. Air, basking-surface and water temperatures are kept separate, and where sources disagree both are shown. “Study” notes report what a paper measured, not a universal rule.

Federal legal snapshot

No federal permit to keep

USDA Animal Welfare Act. Keeping a pet for yourself doesn't need a federal license. Dealers (including many breeders who sell wholesale or sight-unseen) and exhibitors (including encounters and paid programs) generally need a USDA license and inspections; some small-scale breeders and retail sellers are exempt. 184

State law decides most of it. Each state sets its own permits and bans for exotic, native, venomous and dangerous animals, and cities and counties can be stricter. Find your state agency →

Animal Welfare Act standards

Warm-blooded animals not covered elsewhere (Subpart F). Applies to USDA-licensed or registered dealers, exhibitors (including encounters and paid programs) and research facilities. Private pet owners are not covered. These are legal minimums, not best care; the species care on this page goes further.

Facilities must be structurally sound and strong enough for the species, with reliable power and water, protected food storage and proper waste disposal. §3.125
Indoors: temperature regulated to protect from extremes, adequate ventilation without drafts, and lighting suited to the species that protects animals from excessive light. §3.126
Outdoors: shade from overheating sun, shelter suited to the local climate, and drainage. Animals must be acclimated before facing climate extremes. §3.127
Outdoor facilities need a perimeter fence at least 8 ft high for potentially dangerous animals (large cats, bears, wolves, rhinoceros, elephants) and 6 ft for others, at least 3 ft from the enclosure, unless USDA approves otherwise. §3.127
Space must allow each animal to make normal postural and social adjustments with adequate freedom of movement. Poor condition, stress or abnormal behavior can show the space is inadequate. §3.128
Food must be wholesome, palatable and of enough quantity and nutritive value for the species, age and condition, fed at least once a day except during hibernation, normal fasts or veterinary treatment. §3.129
Water must be available as often as needed for health and comfort, in clean receptacles. §3.130
Animals sharing an enclosure must be compatible, and must not be housed near animals that interfere with their health or cause them discomfort. §3.133
There is no general enrichment rule for this subpart; enrichment requirements apply to primates, birds and (exercise) dogs. §3.128
