What are lemurs like?
What are lemurs like? Lemurs are small arboreal primates that live on the island of Madagascar and on the nearby Comoros Islands. There are numerous lemur species, all of them slightly different from one another.
How many lemurs are there in the world?
Eighty-eight species of lemurs exist today, all of which are native to Madagascar [source: Smithsonian National Zoo]. In fact, the reason lemurs have been able to thrive in Madagascar is because no other primates inhabit the island.
Where are lemurs kept?
One of the foremost lemur research facilities is the Duke Lemur Center (DLC) in Durham, North Carolina. It maintains the largest captive lemur population outside of Madagascar, which it maintains for non-invasive research and captive breeding.
Are lemurs ancestral primates?
Like other strepsirrhine primates, such as lorises, pottos, and galagos, they share ancestral (or plesiomorphic) traits with early primates. In this regard, lemurs are popularly confused with ancestral primates; however, lemurs did not give rise to monkeys and apes ( simians ). Instead, they evolved independently in isolation on Madagascar.
Which of the following is the only place living lemurs are found in the wild?
Lemurs are primates found only on the African island of Madagascar and some tiny neighboring islands. Because of its geographic isolation, Madagascar is home to many amazing animals found nowhere else on Earth.
Where do lemurs exist in the wild quizlet?

What feature does a Strepsirhine have?
Living strepsirrhines are united by at least three specialized features of 'hard anatomy' that can be identified in fossils: their unusual dental tooth comb (and associated small upper incisors), the laterally flaring talus, and the grooming claw on the second digit of their feet (Figs. 4.1, 4.2).
Is lemur a monkey?
Lemurs are prosimians, a type of primate. Other primates include monkeys, apes and humans. Lemurs are endemic to Madagascar, where they evolved in isolation. Unlike monkeys, lemurs have a moist nose and rely more heavily on their sense of smell.

What single factor has most strongly contributed to the rapid population growth in the human population witnessed over the last 150 years?
Humans have increased their carrying capacity through technology, urbanization, and harnessing the energy of fossil fuels.
Why did lemurs go extinct?
The lemurs that didn't escape to the island met a very different fate. African lemurs became extinct when they couldn't compete with other primates for food , and the same thing happened elsewhere around the world. A 30-million-year-old fossil of a modern dwarf lemur, Cheirogaleus, was found in central Pakistan, for example [source: National Geographic News ]. But no such animal exists in that part of the world today.
How many species of lemurs are there in Madagascar?
They're nocturnal, insectivorous creatures (meaning they feed on insects) with small bodies, long noses and large eyes. Eighty-eight species of lemurs exist today, all of which are native to Madagascar [source: Smithsonian National Zoo ].
What are the two suborders of primates?
Basically, primates can be broken down into two suborders: anthropoids and prosimians. Monkeys, apes and humans are anthropoids; lemurs are prosimians. Like other primates, prosimians rely on their moist noses and strong senses of smell to find food and identify individuals in their social group.
What animal sits in the desert?
A ringtailed lemur suns itself in the desert sand. The lemur is known for this signature sitting position. See more African animal pictures .
Why do monkeys survive in Madagascar?
In fact, the only reason they still survive there today is because of Madagascar's isolation. Competing primates like monkeys and apes never made it to Madagascar.
When did the Prosimian suborder evolve?
In this girl-power-driven suborder, females get the best food, defend the group and choose their own mates. Prosimians evolved before anthropoids. The first prosimian fossil dates back 55 million years ago. The first monkey fossil dates back 45 million years ago, and the first ape, 35 million years ago.
Do lemurs use their teeth?
They also groom themselves and others in their group. But while anthropoids use their fingers to groom, lemurs use their teeth as a comb. Anthropoids are omnivores — they usually don't actively hunt and rely mostly on vegetation and insects as food sources.
How do lemurs help the ecosystem?
Did you know that lemurs play a huge role in maintaining forest diversity, structure and dynamics through the movement of seeds? Some lemur species play a significant role in their ecosystem by being seed dispersers. But what does this actually mean?
How many species of lemurs are there?
There are over 100 species of lemur, in all shapes and sizes. Image showing illustration of Megaladapis edwardsi from Lemurs of Madagascar book. With an estimated 112 species, lemurs come in all shapes and sizes.
What is a ruffed lemur?
Ruffed lemurs, like the black and white ruffed lemur, is a prime example of a lemur species that acts as a key seed disperser. Individual lemurs can get pollen or seeds stuck on their fur as they search for fruits and nectar. Then, they pass this pollen and seeds on to other flowers.
What is the largest lemur in the world?
The indri is the largest of the living lemurs, however subfossil records show extinct lemurs as large as 85kg! Most notably, Megaladapis edwardsi that used to roam the island of Madagascar and was thought to be the size of a gorilla! (2).

What is the significance of lemurs?
Lemurs play a significant role in culture to Malagasy people and are subject to many fady, or cultural taboos and traditions that originate from ancient folktales.
Where do lemurs live?
Madagascar is the fourth largest island in the world, located on the eastern coast of Africa, in the Indian Ocean. More than 150 million years ago it split away from the African continent as a result of the movement of continental plates. Following this separation, the living species that inhabited the island evolved independently. 75% of the island's wildlife are endemic, meaning that they are only found on this island.
What is the most distinctive lemur?
They are mostly diurnal, and they are smaller than ruffed lemurs. Ring-tailed lemur (Lemur catta): This is the most distinctive lemur of them all, recognizable for its tail with rings of gray and black. Ring-tailed lemurs are endangered.
How do lemurs behave?
Lemurs are arboreal mammals. They have adapted to living in trees, and they are very agile creatures that can climb and jump with ease. However, they are also fast-moving on the ground, although they prefer the protections of trees. They are active during both day and night, although there are some species that are more nocturnal than others. Their coat coloring means that they can often go by unnoticed. As you can see, lemurs have adapted to their habitat in different ways.
What color are ruffed lemurs?
Red ruffed lemurs have a cream or pale patch on the crown behind their neck; you can see one in the picture. Brown or true lemur (Eulemur): This lemur genus has a more uniform coloring, which is reddish brown. They are mostly diurnal, and they are smaller than ruffed lemurs.
How much does a lemur weigh?
Lemurs can weight anywhere from 9 kg (20 lb) in the case of the largest lemur species, the indri or babakoto ( Indri indri) to 30 g (1.1 oz) in the case of the smallest one, Madame Berthe's mouse lemur ( Microcebus berthae ). Their hands have five fingers, with an opposable thumb. They also have nails instead of claws.
What are the different types of lemurs?
The taxonomic classification of the lemur superfamily isn't a simple one. There are about a hundred species, which can be told apart by their coat colo¡r, shape and size. Here are some of the most distinctive lemur species: 1 Ruffed lemur (Varecia): The face and extremities of this genus are black, and their coat is usually reddish or white. Red ruffed lemurs have a cream or pale patch on the crown behind their neck; you can see one in the picture. 2 Brown or true lemur (Eulemur): This lemur genus has a more uniform coloring, which is reddish brown. They are mostly diurnal, and they are smaller than ruffed lemurs. 3 Ring-tailed lemur (Lemur catta): This is the most distinctive lemur of them all, recognizable for its tail with rings of gray and black. Ring-tailed lemurs are endangered. 4 Greater bamboo or broad-nosed gentle lemur (Prolemur simus): This is one of the largest lemurs, and it mainly feeds on bamboo. It is brown in color and has small ears. The greater bamboo lemur is critically endangered.
How many fingers does a lemur have?
Their hands have five fingers, with an opposable thumb. They also have nails instead of claws. They are very sociable and communicative with members of their own species. Lemurs have a highly developed sense of smell, so they use marking to show possession, as a form of warning and by means of marking their territory.
Where are lemurs found?
Lemurs are a group of highly diverse primates found on the island of Madagascar. Though they are primates, and a close resemblance, they are not considered monkeys. Instead, lemurs developed apart from monkeys and apes, and they are actually more closely related to lorises and bush babies. Read on to learn about the lemur.
How many different species of lemurs are there?
There are almost 100 different species of lemur, and each is different from the next. Some species are black and white, some have black rings on their tails, and some have burnished orange fur.
What is a lemur's claw called?
They have some very unique anatomy and adaptations. Toilet-Claw – Lemurs possess an odd, compressed fingernail called a “toilet-claw.”. Yes, we said toilet-claw! This claw can be found on a number of different primate species, and is used for grooming and parasite removal.
How to tell if a lemur is a monkey?
Tell-Tail Sign – One easy way to tell lemurs are not monkeys is to take a close look at their tails. While their tails are long and moveable, they are not prehensile. Monkeys have prehensile tails that they can use as a third limb, lemurs’ tails cannot be used to grab onto objects, but simply help the animals balance.
Why are lemurs endangered?
Humans have been decimating lemur populations since the day we set foot on Madagascar. Lemurs are hunted as bushmeat, and illegally captured for the pet trade. Deforestation may be the greatest threat to to this animal’s survival. More and more lemur habitat is cut down, as farming and urbanization of Madagascar continue.
Why is the lemur habitat being cut down?
More and more lemur habitat is cut down, as farming and urbanization of Madagascar continue. The human population of Madagascar, while increasing, is very impoverished. This can lead to difficulty with setting conservation efforts into motion, especially when habitat destruction means profits for those involved.
What do lemurs eat?
Different lemur species take advantage of different food sources. Smaller species tend to feed on insects and fruit most often. Larger species are more likely to be herbivores, and they feed on plant material primarily. They are known to feed on 82 different species of native plants, and 17 species of invasive plants.
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.
Why are lemurs called lemurs?
According to Linnaeus' own explanation, the name was selected because of the nocturnal activity and slow movements of the slender loris.
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.
How many competing lemur phylogenies are there?
There are two competing lemur phylogenies, one by Horvath et al. (top) and one by Orlando et al. (bottom). Note that Horvath et al. did not attempt to place the subfossil lemurs .
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).
Description
Diet
- The coat color, morphology, lifestyle and eating habits vary slightly depending on which part of the island they inhabit. Lemurs are omnivorous animals, which means that they eat fruits, leaves, insects, flowers and small vertebrates. The richness of their diet is entirely dependent on the existence of vast forests: the biggest lemurs tend to prefer a herbivorous diet, but they will still e…

Conservation status
- According to the IUCN (International Union for Conservation of Nature), lemurs are considered the most endangered mammals in the world, as 90% types of lemurs are in a critical situation.
Climate
- The island's climate is highly variable. There are two main seasons: a warm, rainy season from November to April and a season of milder temperatures and little rainfall from May to October. The landscapes and ecosystems of Madagascar are also very diverse. The eastern part of the island is home to tropical forests and has a wetter climate, while the center is cooler, drier and d…
Evolution
- Lemurs have adapted to survive the different climates within the island, causing a diversification that paved the way to the evolution of different lemur species and subspecies. In addition, lemurs barely have any competitors or threats on the island, allowing them to evolve without being threat of predators.
Environment
- The environment has changed since the arrival of mankind to the island about 2000 years ago, mainly through the felling of forests to create pastures and farmlands. It could be said that human beings are their biggest threat.
Taxonomy
