What are lemur families like?
Who rules the lemur world? In lemur society, females rule. At the centre of lemur groups is a female leader who leads the group to food and shelter and gets first access to resources. This is very rare in mammals, as usually the male takes the lead. Female lemurs show their dominance through marking their territories.
Where do lemurs live?
In the wild, lemurs live in only one place in the world: Madagascar. Madagascar is a biodiversity hotspot because many of the island’s plant and animal species are endemic, meaning that they are found nowhere else.
What do lemurs eat?
Different lemur species eat different things, from fruits, leaves, and tree sap to insects and even chameleons. Some lemurs, such as the black lemur, are frugivores, meaning their diet consists mainly of fruit.
Do lemurs like to “move it, move it”?
Yes! Like many primates, lemurs are comfortable in the trees. Some lemurs, like the sifakas, are almost entirely arboreal.

In fact, sifakas have been known to clear distances over 30 feet in one leap!
What dangers do lemurs face?
Like most small mammals, lemurs have natural predators in the wild. Baby lemurs and smaller species are especially vulnerable to natural predators such as large birds and the infamous fossa. The fossa is a cat-like carnivore that is also endemic to Madagascar. Fossa are excellent climbers, and are just as comfortable in a tree as a lemur. This gives fossa an advantage when hunting, and makes lemurs one of their top prey.
How can you help lemurs?
Traveling to Madagascar is an adventurous way to help lemurs, as ecotourism provides income for local people while protecting lemur habitat across the island.

It is also more rewarding to see lemurs in their natural habitat!

What is the IUCN Red List?
In 1964, the International Union for the Conservation of Nature (IUCN) established the Red List of threatened species. The Red List details the conservation status of the world’s plant and animal species and provides assessments on the population status, habitat range, ecology, threats, and areas of future research focus for all listed species.
How many species are on the Red List and how are the species categorized?
Currently over 120,000 species are listed on the Red List, including mammals, birds, fish, and corals. Each species is assigned one of nine categories reflecting their current conservation status in the wild: Not Evaluated, Data Deficient, Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild, and Extinct.
How frequently is the Red List updated?
Species are assessed every several years in a series of meetings around the world with scientists and conservation experts who have expert knowledge of each species. The most recent assessment was completed in 2020, which followed a 2012 assessment.
What does it mean for a species to be critically endangered?
Red List assessments are complicated and difficult to explain. In simple terms, if a species is critically endangered, that means it is in real trouble. If we don’t solve the problems causing their decline very soon, it will be too late and the species is likely to go extinct in the wild.

Why are lemurs endangered?
Lemurs are threatened by a host of environmental problems, including deforestation, hunting for bushmeat, live capture for the exotic pet trade, and climate change. All species are listed by CITES on Appendix I, which prohibits trade of specimens or parts, except for scientific purposes. As of 2005, the International Union for Conservation of Nature (IUCN) listed 16% of all lemur species as critically endangered, 23% as endangered, 25% as vulnerable, 28% as "data deficient", and only 8% as least concern. Over the next five years, at least 28 species were newly identified, none of which have had their conservation status assessed. Many are likely to be considered threatened since the new lemur species that have been described recently are typically confined to small regions. Given the rate of continued habitat destruction, undiscovered species could go extinct before being identified. Since the arrival of humans on the island approximately 2000 years ago, all endemic Malagasy vertebrates over 10 kg (22 lb) have disappeared, including 17 species, 8 genera, and 3 families of lemurs. The IUCN Species Survival Commission (IUCN/SSC), the International Primatological Society (IPS), and Conservation International (CI) have included as many as five lemurs in their biennial " Top 25 Most Endangered Primates ". The 2008–2010 list includes the greater bamboo lemur, gray-headed lemur ( Eulemur cinereiceps ), blue-eyed black lemur ( Eulemur flavifrons ), northern sportive lemur ( Lepilemur septentrionalis ), and silky sifaka. In 2012, an assessment by the Primate Specialist Group of the International Union for Conservation of Nature (IUCN) concluded that 90% of the then 103 described species of lemur should be listed as threatened on the IUCN Red List, making lemurs the most endangered group of mammals. The IUCN reiterated its concern in 2013, noting that 90% of all lemur species could be extinct within 20 to 25 years unless a US$7 million 3-year conservation plan aimed at helping local communities can be implemented.
Why are lemurs so diverse?
Due to Madagascar's highly seasonal climate, lemur evolution has produced a level of species diversity rivaling that of any other primate group. Until shortly after humans arrived on the island around 2,000 years ago, there were lemurs as large as a male gorilla.
How much does a lemur weigh?
Lemurs range in weight from the 30-gram (1.1 oz) mouse lemur to the 9-kilogram (20 lb) indri. Lemurs share many common basal primate traits, such as divergent digits on their hands and feet, and nails instead of claws (in most species).
What are the characteristics of a lemur?
These traits can include seasonal fat storage, hypometabolism (including torpor and hibernation ), small group sizes, low encephalization (relative brain size), cathemerality (activity both day and night), and strict breeding seasons. Extreme resource limitations and seasonal breeding are also thought to have given rise to three other relatively common lemur traits: female social dominance, sexual monomorphism, and male–male competition for mates involving low levels of agonism, such as sperm competition.
What is the oldest lemur fossil?
However, the oldest lemur fossils on Madagascar are actually subfossils dating to the Late Pleistocene. Once part of the supercontinent Gondwana, the island of Madagascar has been isolated since it broke away from eastern Africa (~160 mya), Antarctica (~80–130 mya), and India (~80–90 mya).
