The ring-tailed lemur is a small animal. 

The ring-tailed lemur is a special animal. 
These animals like to live in groups. They huddle close to stay warm. They also clean each other to stay healthy.
They are active during the day. They like to sit in the sun. 
They use their noses to talk. They rub their bodies on trees to leave a scent. This helps them tell others where they are.
These lemurs are very loud. They make many sounds to talk to their friends. They are very smart too!
The ring-tailed lemur is a famous primate. 
These lemurs live in social groups called troops. A troop can have up to 30 members. In these groups, females are the leaders. To stay warm, they huddle close together. They also groom each other. This helps them stay connected and removes tiny insects.
Ring-tailed lemurs are diurnal. This means they are active during the day. They like to sunbathe to get warm. They sit upright on their tails. They often open their palms and close their eyes. 
They use scent to communicate. They have scent glands near their eyes and anus. Males use these for "stink fights." They wipe scent on their tails and wave them at rivals.
Sadly, these lemurs are endangered. People hunt them and destroy their homes. There may be only 2,000 left in the wild.
The ring-tailed lemur is a famous primate from Madagascar. 

Life in a troop follows many interesting patterns. To stay warm, the lemurs huddle together in groups. They also spend time grooming each other to stay clean. This grooming helps remove tiny insects from their thick fur. Ring-tailed lemurs are diurnal, so they are active during the day. They love to sunbathe to soak up the warmth. 
Scientists have studied these animals for a long time. The name "lemur" comes from a Latin word for ghosts. 
There are many important facts about how they live. A ring-tailed lemur weighs about 2.5 kilograms on average. Their bodies can be between 40 and 46 centimeters long. Their tails can reach 58 to 64 centimeters in length. They are omnivores, so they eat many different types of food. They are also very vocal and make many different sounds. They use these calls to keep the group together or to warn of danger. They also use scent glands near their eyes and anus to mark their home.
Understanding lemurs helps us see how they fit into our world. Even though they have small brains, they are very smart. Experiments show they can understand basic math and use tools.
The ring-tailed lemur (Lemur catta) is a medium-to-large strepsirrhine primate. Strepsirrhines are a group of primates characterized by having "wet noses." This species is the most famous member of the lemur family. It is the only living member of the genus Lemur. These primates are endemic to Madagascar. This means they are found naturally nowhere else on Earth. They live in various environments, ranging from gallery forests to spiny scrub in southern Madagascar. 
Social life is central to the survival of the ring-tailed lemur. They live in highly organized social groups called troops. A single troop can contain up to 30 individuals. These groups are female-dominant, meaning females hold the primary social power. To maintain these social bonds, members engage in mutual grooming. This behavior helps clean the fur of insects and reaffirms familial connections. They also huddle together to share body heat and stay warm. 
Ring-tailed lemurs are strictly diurnal, which means they are active during daylight hours. Because of this, they spend significant time sunbathing. They sit upright on their long tails to expose their white belly fur to the sun. During these moments, they often sit with open palms and closed eyes. 

Anatomy plays a vital role in how these lemurs move and interact. Their most recognizable feature is a long, bushy tail with alternating black and white rings. The tail is not prehensile, so it cannot grasp branches like some other primates. Instead, it is used for balance, communication, and maintaining group cohesion. The tail's ring pattern closely matches the number of caudal vertebrae in the animal. 
The history of the name "lemur" is quite interesting. The term comes from the Latin word *lemures*, which refers to specters or ghosts. Carl Linnaeus originally used the name for the slender loris due to its nocturnal habits. It was later applied to the primates of Madagascar. The species name, *catta*, refers to the animal's cat-like appearance and purring vocalization. In 1771, Thomas Pennant called them the "ring-tailed maucauco." Later, George Shaw introduced the English name "ring-tailed lemur" between 1792 and 1796.
Scientists have long debated the evolutionary history of this species. Molecular evidence suggests lemurs may have arrived in Madagascar via a single rafting event 50 to 80 million years ago. This small ancestral population underwent evolutionary radiation to create the diverse lemurs seen today. There is ongoing scientific discussion regarding the relationship between ring-tailed lemurs and bamboo lemurs (genus *Hapalemur*). While some molecular data suggests a close link, other physical traits, such as snout length, suggest otherwise. 
Despite their popularity in zoos, ring-tailed lemurs face severe threats in the wild. They are currently listed as endangered on the IUCN Red List. Habitat destruction is a major cause of their decline. Local farmers often use slash-and-burn deforestation to create fields for crops and livestock. Local hunting for bushmeat and the exotic pet trade also impact their numbers. As of early 2017, the wild population was estimated to be as low as 2,000 individuals. This decline makes them critically endangered and highlights the urgent need for conservation efforts.
