Ring-tailed lemurs, or Lemur catta, are prosimians, a paraphyletic group that includes all Strepsirrhini and Tarsii, the most ancestral of the primates. They are native to Madagascar and are highly social, living in groups of up to 30 individuals. They are easily recognised by their long, bushy tails that feature 13 alternating black and white bands. Male ring-tailed lemurs have scent glands on their chests, rumps, and wrists, with a spur-like fingernail called a horny spur. They use this to mark their territory by raking the trunks of trees. Ring-tailed lemurs have slender and semi-dexterous fingers with flat, human-like nails.

Ring-tailed lemurs have flat, human-like nails
Ring-tailed lemurs, also known as Lemur catta, are a species of lemur native to Madagascar. They are highly social, living in groups of up to 30 individuals, known as "troops". They are also one of the most vocal primates, using a variety of vocalizations for group cohesion and predator alarm calls.
Male ring-tailed lemurs have a unique scent-marking behaviour. They have scent glands on their chests, rumps, and wrists, with a spur-like fingernail, known as a horny spur, on the wrist glands. They use this spur to rake the trunks of sapling trees, leaving a gash filled with their scent. This behaviour is a form of territorial marking, and males will also engage in "stink fights" by dousing their tails with pheromones and wafting them at opponents.
Ring-tailed lemurs are prosimians, a group that includes all Strepsirrhini and Tarsii, the most "ancestral" of the primates. They are highly adaptable, being able to organize sequences, understand basic arithmetic operations, and select tools based on functional qualities, despite their relatively small brain size compared to other primates.

They are prosimians, a group that includes the most ancestral of primates
Ring-tailed lemurs have fingernails, toenails, and opposable thumbs, which are adaptations for their life in the trees. They are prosimians, a group of primates that includes the most ancestral or primitive of primates. Prosimians are a diverse group of primates with primitive characteristics and are found in Southeast Asia, Africa, and on the island of Madagascar. They are generally smaller-brained compared to other placental mammals and live in simpler social settings. They are also frequently nocturnal and lack the colour vision of higher primates.
Prosimians are a paraphyletic group that includes all Strepsirrhini and Tarsii, which are considered the most ancestral of primates. The first undisputed primates, with characteristics similar to those of lemurs and lorises, began to appear during the Eocene Epoch (about 56 million to 33.9 million years ago). The earliest ancestors of the higher primates, such as primitive monkeys and apes, emerged during the Oligocene Epoch (about 33.9 million to 23 million years ago). Therefore, prosimians are more closely related to the ancestral primates than to the higher primates.
The prosimian group includes a diverse range of primates, such as lemurs, lorises, galagos (bush babies), pottos, sifakas, and aye-ayes. They are placed in the suborder Strepsirrhines and are considered to have more primitive characteristics than simians (monkeys, apes, and humans). While prosimians were once dominant in the trees, they were eventually replaced by monkeys, which were stronger in that environment.
Ring-tailed lemurs, or Lemur catta, are a type of prosimian primate native to Madagascar. They have distinctive black and white rings on their long tails and grey or brown fur with white bellies. They are highly social, living in groups or "troops" of up to 30 individuals. They are also one of the most vocal primates, using various vocalizations for group cohesion and predator alarm calls. Despite their relatively small brain size, ring-tailed lemurs have shown the ability to organize sequences, understand basic arithmetic, and select tools based on functionality.

They are native to Madagascar and are highly social, living in groups of up to 30 individuals
Ring-tailed lemurs, or Lemur catta, are native to the island of Madagascar, where they are found in the southern and southwestern regions. They are highly social animals, living in groups known as "troops". These troops can consist of up to 30 individuals, though some sources state that the average group size is around 15 members. The troops are typically made up of multiple males and a core group of related females, with females socially dominating males in all circumstances. Hierarchy within the troops is established during youth through rough and tumble play, and dominance is enforced through behaviours such as lunging, chasing, cuffing, grabbing, and biting.
The social structure of the ring-tailed lemur is complex and dynamic. Females stay with the troop they were born into, while males tend to migrate between groups every few years. For males, social structure changes can be seasonal, with some migrating between groups during the months of December to May. Established males may transfer every 3.5 years, while younger males may transfer more frequently, approximately every 1.4 years.
Group cohesion is maintained through various behaviours and rituals. Mutual grooming is an important aspect of socialisation, serving to reaffirm social and familial connections while also providing an opportunity to rid each other of insects. The sharing of nests and food is also common, though this can change when resources become scarce, leading to competition within the group. To keep warm and further reinforce social bonds, groups will huddle together, especially during cold mornings. Sunbathing is often a group activity, with individuals sitting in a "sun-worshipping" posture, legs extended outward, and sometimes supported by nearby branches.
Communication within the troops is complex, utilising vocalisations, visual signals such as body postures and facial expressions, and scent-marking. As one of the most vocal primates, the ring-tailed lemur uses a variety of vocalisations for group cohesion and predator alarm calls. They also engage in scent-marking behaviours, such as the unique practice of ""spur-marking", where males impregnate their tails with pheromones and wave them at opponents in "stink fights". Both males and females will also scent-mark objects in their environment by rubbing their faces and bodies on them.

They are one of the most vocal primates and use various vocalizations for group cohesion and predator alarm calls
Ring-tailed lemurs (Lemur catta) are one of the most vocal primates, using a wide range of vocalizations for group cohesion and to alert group members to potential dangers. They are highly social, living in groups of up to 30 individuals, known as "troops". This social structure relies on effective communication, and vocalizations play a crucial role in maintaining group cohesion.
The vocalizations of ring-tailed lemurs can be simple or complex. An example of a simple call is the purr, which expresses contentment. More complex calls are used during predator mobbing, such as a sequence of clicks, close-mouth click series (CMCS), open-mouth click series (OMCS), and yaps. These complex vocalizations are essential for the survival of the group, as they help alert other members to the presence of a predator and trigger appropriate responses, such as mobbing or vigilance behaviours.
The most commonly heard vocalizations are moans, which indicate low-to-moderate arousal and contribute to group cohesion, and early-high wails, which signify moderate-to-high arousal and also help maintain group cohesion. Clicks are another commonly used vocalization, acting as a "location marker" to draw attention. These clicks can be part of a complex sequence of vocalizations during predator encounters.
Male ring-tailed lemurs play a significant role in group-wide vocalizations, particularly in high-risk locations. Although female ring-tailed lemurs typically hold the primary role in group defence, males also actively participate in vocalizations that may confuse or drive away predators. This was observed in a study at the Bezà Mahafaly Special Reserve in Madagascar, where male antipredator vocalizations triggered responses from other group members.

They are diurnal, active only during the day, and spend a significant amount of time on the ground
Ring-tailed lemurs, or Lemur catta, are diurnal, meaning they are active during the day and sleep at night. They are native to Madagascar and are the only species in the genus Lemur, though they share the family Lemuridae with many other species. Unlike most other lemurs, ring-tailed lemurs spend a significant amount of time on the ground, up to 40% according to some sources, and up to 80% according to others. They move quadrupedally along the forest floor and even sleep in big, furry, communal heaps right out in the open on grass or rocks.
The ring-tailed lemur is highly social, living in groups or "troops" of up to 30 individuals. They are also one of the most vocal primates, using numerous vocalizations for group cohesion and predator alarm calls. Male ring-tailed lemurs have scent glands on their chests, rumps, and wrists, which they use to mark their territory by raking the trunks of trees with their wrists, leaving a gash filled with their scent. They also participate in "stink fights" by dousing their tails with pheromones and wafting them at opponents.
The average body mass for adult males is 6 pounds (3 kilograms), while females are usually smaller. Their tails can be up to 2 feet long (61 centimeters) and always have a white stripe at the beginning, followed by 13 alternating black and white bands, and ending with a black stripe. Their backs are grey to rosy brown with grey limbs and dark grey heads and necks, and they have white bellies, ears, and faces with dark triangular eye patches and a black nose. They have slender and semi-dexterous fingers with flat, human-like nails, as well as opposable thumbs, which are adaptations for a life in the trees shared by many primates.
In the wild, it is rare for female ring-tailed lemurs to live past 16 years of age, while the male lifespan is less well-known due to their social system. The oldest known wild female was between 18 and 20 years old. In captivity, ring-tailed lemurs weigh slightly more than their wild counterparts, with males weighing on average 5.96 pounds (2705 grams) and females averaging 5.90 pounds (2678 grams).
