Where Ringtail Lemurs Dwell, And Why They’re Endangered
Where Ringtail Lemurs Dwell, And Why They Are Endangered: Ring-tailed lemurs are one of the most distinct and easily recognised lemur species. The Lemur Conservation Network's professional guide can help you learn about this critically endangered animal.
All lemur species, including ring-tailed lemurs, are native to Madagascar, an island off the coast of East Africa.
Lemurs are the world's most endangered mammal species and the world's most endangered vertebrate species.
According to the 2020 IUCN Red List, 98% of lemur species are threatened with extinction, and 31% are endangered, indicating that they are on the verge of extinction in the wild.
Ring-tailed lemurs are listed as vulnerable on the IUCN Red List.
What exactly is a ring-tailed lemur?
Ring-tailed lemurs are small primates about the size of a domestic cat. Adult ring-tailed lemurs weigh between 3 and 3.5 kilogrammes.
Ring-tailed lemurs can survive in the wild for up to 20 years. They are the most common species of lemur found in zoos, where they can live for up to a decade longer.
What is the scientific name for the ring-tailed lemur?
In scholarly literature, the ring-tailed lemur is known as the Lemur catta.
Strepsirrhine primates include ring-tailed lemurs. This category includes lemurs, lorises, and galagos. They are also known as “wet-nosed” primates.
The prosimian group includes all strepsirrhines and tarsiers, including lemurs.
Ring-tailed lemurs can be found in the following locations:
Madagascar, the world's fourth largest island, is home to many lemur species. Ring-tailed lemurs can be found in Madagascar's south and southwest. Summers in this region are hot and humid, winters are mild and dry, and rainfall is variable.
Ring-tailed lemurs are an “adaptable” primate in terms of ecology. This means that they can be found in a variety of environments, including as rocky forests, gallery forests, deciduous forests, spiny forests, and human-influenced open savannas.
Some ring-tailed lemurs have been recorded using caverns to avoid predators and cliff walls to escape the heat.
The thorny woodland may be their harshest habitat. Temperatures are high, and supplies are often in short supply. The Malagasy spiny forest is rare because similar woodlands do not exist elsewhere.
It receives little shade and is dominated by thorny plants and little trees. Ring-tailed lemurs eat on the cactus-like plants' sticky, fat-rich sap.
Over many generations, these lemurs have learnt to manage the region's thorny plants.
What distinguishes ring-tailed lemurs?
Ring-tailed lemurs show off their tails!
Ring-tailed lemurs are distinguished by their 60-inch-long black and white striped tail.
Ring-tailed lemurs have glands on their wrists that generate pheromones (a chemical signal) that they brush on their tails and hurl into the air. This is referred to as “stink flirting.”
Males have horn spurs that cover these glands. They use leaves, sticks, and tree trunks to mark their territory!
Ring-tailed lemurs have a highly developed sense of smell!
Ring-tailed lemurs, like all strepsirrhines, have primitive skull traits, including a primate's tiny brain.
They have long noses and a keen sense of smell. Strepsirrhines are also unique in that they have the same reflective “eye shine” as many other mammals at night, such as deer and foxes.
Ring-tailed lemurs have unique teeth!
Like other lemur species, ring-tailed lemurs have a “dental ridge.” The bottom incisors and canines are closely pinched in this uncommon dental adaptation.
Lemurs use their oral comb to groom themselves and other group members. They have nails on their hands and feet, save for the second toe.
This “toilet claw serves personal hygiene.”
When and how do lemurs go outside, and how do they move?
Ring-tailed lemurs are diurnal, which means they are primarily active throughout the day. They are the most terrestrial lemur species, spending much time in trees foraging, travelling, and sleeping.
Lemurs on the ground and in trees typically move quadrupedally (on all four limbs). They are also fantastic jumpers!
During the day, ring-tailed lemurs are frequently seen sunbathing with their arms outstretched. This is usually referred to as “sun worship.”
The group builds “lemur balls” to keep warm while sleeping.
Ring-tailed lemurs eat what?
Ring-tailed lemurs are either omnivores or frugivores. They occasionally eat fruits, flowers, leaves, bark, plant sap, insects, and mineral-rich soil.
Their diet is mainly governed by their environment and the time of year (wet or dry season).
Ring-tailed lemurs are very important in seed dissemination. When lemurs eat fruit, they also devour the seeds.
The lemurs' digestive tract does not break down the seeds. Thus, they end up back in the forest with their excreta. Many of these seeds will germinate and grow into new trees!
What is the name of a group of ring-tailed lemurs?
Ring-tailed lemurs live in large social groups known as “troops” of three to thirty individuals.
After sexual development, males establish distinct groups. Females and males are born into the same group.
Females outnumber males in ring-tailed lemur society. Female lemurs prefer grooming and feeding, including first access to high-value foods such as fruit.
Troops command regions and each soldier is accountable for protecting his or her zone when others enter. Females are at the forefront of these battles, and their progeny must hold firm.
What puts them in danger? What dangers do they face?
Predators in their natural habitat
The feline fossa is the ring-tailed lemur's most common natural predator (also called; Cryptoprocta ferox).
This predator is common throughout Madagascar and frequently hunts lemurs in trees. Lemurs are hunted by large birds of prey, such as the Madagascar harrier (particularly youngsters).
Ring-tailed lemurs use a variety of strategies to protect themselves from predators, including keeping a lookout and warning alarm calls.
On the other hand, the natural predator-prey dynamic is vital in any ecosystem. It is not a major threat to lemur survival in Madagascar.
The greatest serious threat to wild ring-tailed lemurs is habitat loss. Madagascar has been classified as a hotspot for biodiversity.
Slash-and-burn agriculture is common in southern Madagascar, home to ring-tailed lemurs. This increases the risk of flames spreading into protected areas such as national parks and reserves.
Lemur forests become fragmented and patchy as habitat is lost. This makes it more difficult for men to join other units, limiting genetic variety.
Adapting to changing environmental conditions and diseases requires genetic variety in animals, which is critical for species survival.
