It has long, muscular legs which it uses to propel itself from trunk to trunk. Three lemur species are especially threatened, with less than 2,500 individuals predicted for Cheirogaleus sibreei, and heavy hunting pressure for the relatively small populations of Indri indri and Hapalemur occidentalis. It is monogamous and lives in small family groups, moving through the canopy, and is purely herbivorous, feeding mainly on leaves but also seeds, fruits, and flowers.

Other vocal categories include the "grunt", "kiss", "wheeze", and "hum". Babakoto is most commonly translated as "ancestor" or "father", but several translations are possible. This study employs genetic and demographic analyses to estimate demographic parameters relating to the historical population dynamics of a wild lemur population, Verreaux's sifaka (Propithecus verreauxi). do not recognize this classification,[11] and recent genetic and morphological work suggests the variation in the indri is clinal. [11], Due to these color variations, Colin Groves listed two subspecies of the indri in 2005: The dark Indri indri indri from the northern part of its range and the relatively pale Indri indri variegatus from the southern part.

Daily frequency of song is highest during the indri's breeding season from December to March. The round head has a pointed face and round, furry ears. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. This represents an increase of 12 threatened species from the IUCN's last lemur population assessment in July 2012. [11], Only one indri has lived over a year in captivity and none have bred successfully while captive.[19]. Female lemurs are ready to produce offspring of their own at 7 - 9 years old. While population estimates are uncertain (1 000 – 10 000 individuals), the population appears to be rapidly shrinking and may diminish by 80% over the next 3 … Ranging in size from the one-ounce pygmy mouse lemur to the 20-pound indri lemur, these primates are only found on Madagascar, an island nation located off the southeast coast of … These arboreal animals travel between trees by taking vertical leaps. The indri (/ ˈ ɪ n d r i / (); Indri indri), also called the babakoto, [citation needed] is one of the largest living lemurs, with a head-and-body length of about 64–72 cm (25–28 in) and a weight of between 6 to 9.5 kg (13 to 21 lb).It has a black and white coat and maintains an upright posture when climbing or clinging. 1992). Indri (Indri indri) is the largest extant lemur species and the genus is monotypic. Mean home range size is 27 ha. That brother became the first human, and the brother who stayed in the forest became the first indri. This study employs genetic and demographic analyses to estimate demographic parameters relating to the historical population dynamics of a wild lemur population, Verreaux's sifaka (Propithecus verreauxi). In the broad sense, the term lemur applies not only to the typical lemurs (family Lemuridae) but also to the avahis, sifakas, indri… Less than 20 percent of … It is now confined to a stretch of approximately 500 kms of the north and central eastern rain forest, a much smaller area than it was found in even a few decades ago. The experts provisionally classified 38 lemur species as critically endangered, 44 endangered and 23 vulnerable on the IUCN Red List. A single performance lasts for up to 3 minutes and may be heard by humans from a distance of up to 1.2 miles (2 km). As a result, they are perhaps the most threatened mammal group on earth. Currently, this species is classified as Critically Endangered (CR) and its numbers are decreasing. The loudest lemur is the indri, whose calls can be heard up to 2 km (1.2 mi) or more[50][61] and thus communicate more effectively the territorial boundaries over its 34 to 40 hectares (0.13 to 0.15 sq mi) home range. For the first few months of their lives, young lemurs cling onto the belly of their mother. The Lemur Conservation Foundation works to conserve and protect five lemur species at its reserve in Myakka City, FL and 11 found in the two protected areas in Madagascar supported by LCF.

Fully updated in February 2019, the Duke Lemur Center database allows visitors to view and download data for more than 3,700 animals representing 27 species of lemurs, lorises, and galagos. This is one of the largest Lemurs found in the world. The endangered indri, in particular enjoy space. It lives in small groups consisting of the mated male and female and their maturing offspring. The coloration of their fur largely depends on the locality. The population is estimated to be less than 10,000 individuals. The silky fur is mostly black with white patches along the limbs, neck, crown, and lower back.
