Geographic Range
Ring-tailed lemurs are found only in southern and southwestern Madagascar. They prefer
gallery forests, forests near and following the riverbanks, but can be found in dry
scrub, montane humid forests, and deciduous forests. They tolerate a temperature range
of -12 to 48 Celsius.
- Other Geographic Terms
- island endemic
Habitat
Ring-tailed lemurs are found in three distinct habitats in south and southwestern
Madagascar: continuous canopy forest, brush and scrub forests, and mixed forests.
Continuous canopy forests in this region are dominated by Tamarind trees (
Tamarindas indica
) and other large trees reaching 20-25 meters in height. Brush and scrub forests are
drier than open forests and lower in height. Although ring-tailed lemurs are found
in all tree habitats, they are most commonly found in the continuous canopy forests.

Physical Description
Ring-tailed lemurs have a body length ranging from 39 to 46 cm in length with a tail
ranging in length from 56 to 63cm and an average body weight of 2.2 kg. The body,
covered in a thick, dense fur, is a solid color ranging from gray to brown, with a
long, thick tail. The tail has thick, well defined, black and white rings from stem
to tip. Typically, individuals have a white face mask, with black outlining the eyes
and nose. They have a lighter colored underbelly ranging from light gray or brown,
to white.
Ring-Tailed Lemurs have four thin fingers and a thumb on their upper and lower appendages,
each ending in a dark colored nail. The thumbs on the upper appendages are not opposable
as the joint is fixed. The first toe on the lower appendage is opposable, is used
while climbing trees in the mid and upper level canopy.
- Other Physical Features
- endothermic
- bilateral symmetry
- Sexual Dimorphism
- sexes alike
- female larger
Reproduction
Ring-tailed lemurs begin mating in April, with a gestation period of 130 to 144 days,
giving birth beginning in August and finishing in September. Females are not reproductively
active until 2.5 years of age, and females of 3 to 4 years of age have a higher chance
of success conceiving and giving birth to healthy offspring than younger females.
Females typically give birth to one or two offspring, more commonly females will only
have one.
Females typically mate with more than one male during estrous. Males will compete
amongst themselves for the right to mate with the females.
- Mating System
- polygynandrous (promiscuous)
Females typically give birth to one or two offspring, more commonly females will only
have one.
Offspring are completely cared for by the mother. Newborns spend their first two weeks
of life riding on the underbellies of their mothers. After the first two weeks the
young ride on the backs of their mothers and begin to explore their surroundings.
The males in the troops do very little for the young. The young are weaned starting
at eight weeks of age, until they are fully weaned at five months, all nutrition is
obtained from the mother.
There is a high infant mortality rate; 30 to 50% of infants do not make it through
their first year of life. This mortality rate decreases if the mother is older in
age, or has previously given birth.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- viviparous
Care of the young lies solely with the mother, with males in the group have little
to no impact on raising young. Females are responsible for grooming, feeding, weaning,
and teaching their young.
Females in the troop have been frequently observed caring for other female's offspring
as well as babysitting, feeding and grooming.

Lifespan/Longevity
Ring-tailed lemurs typically live to be 16 years old, with the oldest known ring-tailed
lemur living to be 33 years old in captivity. Limits to lifespan in the wild include
habitat loss and limited resources.
Behavior
Ring-tailed lemurs live in groups of 15 to 20 individuals called troops. Females stay
with the same troop they were born into, while the males will typically move between
troops every 2 to 5 years.
These troops are highly social with complex interactions. Hierarchy is typically established
in their youth through rough and tumble play. All females are dominant over all males.
The lowest ranking female is still higher in the social hierarchy than the highest
ranking male.
- Key Behaviors
- arboreal
- scansorial
- saltatorial
- motile
- sedentary
- social
Home Range
Ring-tailed lemurs have a daily home range of 1000 meters from where they woke up.
The troop will slowly meander from just before dawn until dusk looking for food. Troops
will have a larger home range if their habitat has more sparse resources.
Communication and Perception
Ring-tailed lemur communication is complex. Visual communication signals, such as
body postures and facial expressions are used, in addition to vocal communication.
Ring tailed lemurs are known to use scent marking, and even to engage in "stink battles"
with one another, where secretions from scent glands are rubbed onto the tail, then
wafted at opposing animals. Tactile communication is important between mothers and
their young, as well as between mates. This includes grooming, play, and mating.
- Other Communication Modes
- pheromones
- scent marks
Food Habits
Ring-tailed lemurs are opportunistic omnivores. They can and will eat whatever is
easily available to them including fruits, leaves, stems, flowers, exudates (resin,
latex, sap), spiders, spider webs, chameleons, caterpillars insects, small birds,
and termite mounds. The most important food source in the fruit from the Tamarind
tree. The Tamarind is found in all three habits where lemurs are known to live.

Predation
Ring-tailed lemurs travel in groups, known as troops, to deter predators that hunt
singular prey. Predatory pressure can come from raptor birds, fossas (
Cryptoprocta ferox
), civets (
Civettictis civetta
), domestic cats (
Felis catus
), snakes, and brown lemurs (
Eulemur fulvus
).
Ecosystem Roles
Ring-tailed lemurs contribute to the ecosystem by spreading seeds through their feces.
Along with the other species of lemurs they are responsible for several wildlife reserves
being put into place. These reserves help preserve the environment all other plant
and animal species in the area.
They also contribute to other food webs as a food source for fossas and civets.
- Ecosystem Impact
- disperses seeds
- creates habitat
Economic Importance for Humans: Positive
Ring-tailed lemurs have already improved the economy of Madagascar. Ring-tailed lemurs
are a common draw for ecotourism in the southern and southwestern portion of the island
country.
- Positive Impacts
- ecotourism
- research and education
- controls pest population
Economic Importance for Humans: Negative
There are no negative impacts of ring-tailed lemurs on humans.
Conservation Status
Ring-tailed lemurs are classified as Near Threatened (NT) on the IUCN Red List in Appendix I of CITES.
