* Solitary: Some lemur species, such as the aye-aye and the bamboo lemur, are solitary by nature and prefer to live alone. They may come together for mating purposes or to share food resources, but they generally maintain their own individual territories.
* Groups: Other lemur species, such as the ring-tailed lemur and the sifaka, are social animals and live in groups called troops. These groups can range in size from a few individuals to several dozen. Members of the group maintain close social bonds through various behaviors such as grooming, vocalizations, and cooperative foraging.
* Territorial and Aggressive: Lemurs are territorial animals, and they may exhibit aggression towards other lemurs that encroach on their territory. This aggression can range from vocalizations and displays to physical fights. In some cases, lemurs may even kill intruders if they perceive a threat to their group or resources.
* Interactions Between Species: In areas where multiple lemur species coexist, interactions between different species can vary. Some species may be more tolerant of each other, while others may engage in competitive or aggressive behaviors. For example, the black lemur and the brown lemur are known to compete for food resources and sometimes engage in conflicts over territory.
* Individual Variation: Even within the same species, individual lemurs can exhibit different levels of social interactions and preferences. Some individuals may be more outgoing and social, while others may be more shy and reserved. These variations can contribute to the complex social dynamics observed among lemurs.
