Eulemur
True lemurs, also known as brown lemurs, are the lemurs in genus ''Eulemur''. They are medium-sized primates that live exclusively on Madagascar. The fur of the true lemurs is long and usually reddish brown. Often, sexual dimorphism in coloration (sexual dichromatism) is seen, such as in the black lemur. True lemurs are from in length, with a tail that is as long or significantly longer than the body. They weigh from . True lemurs are predominantly diurnal forest inhabitants, with some species preferring rain forests, while others live in dry forests. They are skillful climbers and can cross large distances in trees by jumping, using their non prehensile tails to aid in balancing. When on the ground, they move almost exclusively on all four legs. True lemurs are social animals and live together in groups of two to 15 members. The diet of the true lemurs is almost exclusively herbivorous – flowers, fruits and leaves. In captivity, they have been shown to also eat insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowned Lemur
The crowned lemur (''Eulemur coronatus'') is a lemur that is long and weighs . Its tail is about long. Description The crowned lemur is endemic to the dry deciduous forests of the northern tip of Madagascar. It eats a diet of mostly flowers, fruits, and leaves. The population is estimated to 1000–10,000 individuals as of 2004, most of which live within the Ankarana Plateau, although there is also a population on the Montagne d'Ambre. This species has a distinctive brown-orange crown on the top of the head. Females have a gray body with an orange crown, and males are a darker reddish brown, crowned with black and orange. Crowned lemurs have a life span of approximately 20 years and reach sexual maturity after 20 months. They give birth usually in late September or early October, after a gestation period of 125 days. The crowned lemur is in the order of Primates as it possesses characteristics such as pseudo-opposable thumbs, binocular vision and is highly intelligent. ''E. co ...

Lemur
Lemurs ( ) (from Latin ''lemures'' – ghosts or spirits) are wet-nosed primates of the superfamily Lemuroidea (), divided into 8 families and consisting of 15 genera and around 100 existing species. They are endemic to the island of Madagascar. Most existing lemurs are small, have a pointed snout, large eyes, and a long tail. They chiefly live in trees and are active at night. Lemurs share resemblance with other primates, but evolved independently from monkeys and apes. 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. Most species have been discovered or promoted to full species status since the 1990s; however, lemur taxonomic classification is controversial and depends on which species concept is used. Lemurs range in weight from the mouse lemur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collared Brown Lemur
The collared brown lemur (''Eulemur collaris''), also known as the red-collared brown lemur or red-collared lemur, is a medium-sized strepsirrhine primate and one of twelve species of brown lemur in the family Lemuridae. It is only found in south-eastern Madagascar. Like most species of lemur, it is arboreal, moving quadrupedally and occasionally leaping from tree to tree. Like other brown lemurs, this species is cathemeral (active during the day and the night), lives in social groups, primarily eats fruit, exhibits sexual dichromatism, and does not demonstrate female dominance. The species is listed as ''Endangered'' by the International Union for Conservation of Nature (IUCN) and is threatened primarily by habitat loss. Taxonomy Together with the twelve other true lemurs (genus ''Eulemur''), the collared brown lemur (''E. collaris'') is a type of lemur belonging to the family Lemuridae. Collectively, lemurs (infraorder Lemuriformes) are classified as strepsirrhine prima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-headed Lemur
The white-headed lemur (''Eulemur albifrons''), also known as the white-headed brown lemur, white-fronted brown lemur, or white-fronted lemur, is a species of primate in the family Lemuridae. It is only found in north-eastern Madagascar. It is arboreal and is usually found in rainforest treetops. It was formerly recognised as a subspecies of the common brown lemur (''Eulemur fulvus''). Physical characteristics The white-headed lemur is a medium-sized lemur and has a horizontal posture, which is suited to its way of movement. It has a long furry tail assisting it in maintaining its balance as it lands from leaping at a considerable distance. Males have gray-brown upper parts, with darker lower limbs and tail, paler gray upper parts, gray head and face and a darker crown. Females have redder-brown upper parts, paler underparts and darker feet than males. The cheeks and beards are white, bushy and pronounced in males, reddish-brown and less bushy in females.

Red-bellied Lemur
The red-bellied lemur (''Eulemur rubriventer'') is a medium-sized strepsirrhine primate with a luxuriant chestnut brown coat. This lemur is endemic to eastern Madagascan rainforests and is distinguished by patches of white skin below the eyes, giving rise to a "teardrop" effect, particularly conspicuous in the male. The species, first identified in 1850, exhibits diurnal behaviour and marked sexual dimorphism. The red-bellied lemur has been studied extensively since the mid-1980s, primarily in Ranomafana National Park. This lemur species is designated as vulnerable according to the IUCN Red List, due to threats endangering habitats from slash-and-burn agriculture in Madagascar. Etymology The various Malagasy names for the red-bellied lemur include , , , , and . In the French scientific literature (Madagascar's second official language is French, due to prior colonisation by France), the species is called .

Mongoose Lemur
The mongoose lemur (''Eulemur mongoz'') is a small primate in the family Lemuridae, native to Madagascar and introduced to the Comoros Islands. These arboreal animals have pointed faces, long, bushy tails, dark-brown upper parts, pale bellies, and beards, which are reddish in males and white in females. They live in family groups and feed primarily on fruit, but also eat leaves, flowers, and nectar, with nectar from the kapok tree making up a large part of their diet during the dry season. They have declined sharply in numbers because of habitat destruction and hunting, and the International Union for Conservation of Nature has rated their conservation status as " critically endangered". Description The mongoose lemur ranges in size from long plus a tail of . Both sexes are born with white beards, but become obviously dimorphic around six weeks of age when the males develop red beards and red cheeks. The males also have lighter faces than the females.

Blue-eyed Black Lemur
The blue-eyed black lemur (''Eulemur flavifrons''), also known as the Sclater's lemur, is a species of true lemur. It can attain a body length of , a tail length of , a total length of , and a weight of . Being a primate, it has strong hands with palms like a human, which have a rubbery texture to give it a firm grip on branches. Its tail is longer than its body and is non-prehensile. Like many of the species in the genus ''Eulemur'', the blue-eyed black lemur is sexually dichromatic. Males are solid black in color, with the hairs sometimes tinged brown at the roots. Females are reddish-brown in color with their underside and outline of their face a lighter tan. They have a dark brown or gray muzzle and the back of their hands and feet are a similar dark color. Both sexes have blue eyes, hence the common name, and are one of the only primates other than humans to consistently have blue eyes. The eyes can range in color from a shocking electric blue, a light sky-blue, or a softer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-fronted Lemur
The red-fronted lemur (''Eulemur rufifrons''), also known as the red-fronted brown lemur or southern red-fronted brown lemur, is a species of lemur from Madagascar. Until 2001, it was considered a subspecies of the common brown lemur, ''E. fulvus''. In 2001, ''E. fulvus'' was split into several separate species, including ''Eulemur rufus'', in which this species was included. In 2008, ''E. rufus'' was split into two species, the red lemur (''E. rufus'') and the red-fronted lemur (''E. rufifrons''). ''E. rufus'' covers the population on the west coast north of the Tsiribihina River and ''E. rufifrons'' covers the population on the west coast south of the Tsiribihina River and the population in eastern Madagascar. The species split was based on genetic and morphological evidence. Mitochondrial DNA analysis indicates that ''E. rufifrons'' may be more closely related to the common brown lemur (''E. fulvus''), white-headed lemur (''E. albifrons'') and Sanford's brown lemur ( ...
