The Sambirano woolly lemur (Avahi unicolor), also known as the Sambirano avahi or unicolor woolly lemur, is a species of woolly lemur native to western Madagascar. [4]
The species are located in Cacamba, on the peninsula of Ampasindava, in northwestern Madagascar. This sub-species is distinguished form Avahi occidentalis by its lack of the white facial outline and the lack of the black hairless circles that surround the eyes. The face itself is slightly more pale than the upper head which creates a slight contrasting facial outline caused by the fur length and consistency (facial hair is short and not curled in comparison to the rest of the body). The contrasting facial outline has a small fur spot above the nose and the forehead that presents the appearance of a dark line. Its eyes are maroon with black, hairless eyelids. The snout is also black and hairless, but the corners of the mouth have a white tint. The fur of the head and body is a light gray-beige, and has a sightly curled, freckled appearance. Its tail is gray-brown or reddish-brown, while the base is a pale brown or cream color. The back is slightly darker in the shoulder-blade area. The lower body's limbs are an off-white color, while the fur on the chest, belly, and inner limbs is fairly thin and light-gray in color. [3]
This species is very poorly known, since so far there have been just a few specimens found. They might be living in the Sambirano region in north-western Madagascar. Probable limits of their distribution are the Sambirano River in the north and the Andranomalaza or Maevarano River in the south. [1]
As it is not known to which degree the species is hunted, deforestation is probably the main threat it has to face. It is listed on Appendix I of CITES. Since there are only a few known specimens in protected areas, additional research and extending the reserves would be essential. [1]
The Indriidae are a family of strepsirrhine primates. They are medium- to large-sized lemurs, with only four teeth in the toothcomb instead of the usual six. Indriids, like all lemurs, live exclusively on the island of Madagascar.
A sifaka is a lemur of the genus Propithecus from the family Indriidae within the order Primates. The name of their family is an onomatopoeia of their characteristic "shi-fak" alarm call. Like all lemurs, they are found only on the island of Madagascar. All species of sifakas are threatened, ranging from endangered to critically endangered.
The woolly lemurs, also known as avahis or woolly indris, are nine species of strepsirrhine primates in the genus Avahi. Like all other lemurs, they live only on the island of Madagascar.
The Bemaraha woolly lemur, also known as Cleese's woolly lemur, is a species of woolly lemur native to western Madagascar, named after John Cleese. The first scientist to discover the species named it after Cleese, star of Monty Python, mainly because of Cleese's fondness for lemurs, as shown in Operation Lemur With John Cleese and Fierce Creatures, and his efforts at protecting and preserving them. The species was first recorded in 1990 by a team of scientists from Zurich University led by Urs Thalmann, but wasn't formally described as a species until November 11, 2005.
The eastern woolly lemur, also known as the eastern avahi or Gmelin's woolly lemur, is a species of woolly lemur native to eastern Madagascar, where it lives in the wet tropical rainforest at low elevations along the eastern coast of the island or they can also inhabit the northern tip of the island with other species. The woolly lemur name refers to their thick, tightly curled hair, whereas their generic name avahi refers to their high-pitched defensive call. The eastern woolly lemur almost has an owl-look with its large eyes, small rounded head, and ears that are mostly hidden. This nocturnal animal weighs 1.0–1.3 kg (2.2–2.9 lb) and reaches a length of 27–29 cm (11–11 in) with a tail of 33–37 cm (13–15 in). Its diet consists mainly of leaves and buds with fruits, flowers, and bark.
The western woolly lemur or western avahi is a species of woolly lemur native to western Madagascar, where they live in dry deciduous forests. These nocturnal animals weigh 0.7–0.9 kg (1.5–2.0 lb). It is a folivorous species.
The common brown lemur is a species of lemur in the family Lemuridae. It is found in Madagascar and has been introduced to Mayotte.
The small-toothed sportive lemur, or small-toothed weasel lemur, is a primate species in the family Lepilemuridae that—like all extant lemurs—is endemic to Madagascar. The species lives in dense rainforest in southeastern Madagascar, and can be found in Ranomafana and Andringitra National Parks. Described in 1894, it was considered either a subspecies or taxonomic synonym of the weasel sportive lemur throughout most of the 20th century. Phylogenetic studies not only support its species status, but also suggest that it is the only eastern Malagasy sportive lemur that is more closely related to western than to other eastern species.
Pariente's fork-marked lemur, or the Sambirano fork-marked lemur, is a species of lemur endemic to the Sambirano region of north-western Madagascar. This lemur has light brown to gray upperparts, a prominent facial fork and dorsal stripe that runs from the tail's tip to the point where it splits on the lemur's head to rejoin at the nose, and a white-tipped tail. It is found in lowland and mid-altitude humid forests and is nocturnal. It is an omnivore, eating tree gum, sap, bud exudes, insects and larvae. It sleeps in nests that have been abandoned by other lemurs, particularly Coquerel's giant mouse lemur. This species is relatively unknown, though it is threatened by habitat destruction. It was previously considered a subspecies of the Masoala fork-marked lemur. It is listed on CITES Appendix I.
Moore's woolly lemur, or the Masoala woolly lemur, is a woolly lemur endemic to Madagascar. It has brown-grey fur and a reddish tail. It is named in honor of the Gordon and Betty Moore Foundation of San Francisco.
The southern woolly lemur, or southern avahi, has been recently recognized as a separate species of woolly lemur in 2006 by Zaramody et al. It is a nocturnal and pair-living species. Groups can range from 2 to 5 individuals. A study in Sainte Luce forest revealed home range varied from 2.2 to 3.5 ha and that males can have larger home range and cover longer daily distances than females, in agreement with the territory defence and mate guarding hypotheses.
The Betsileo woolly lemur or Betsileo avahi is a species of woolly lemur native to southeastern Madagascar, in the District of Fandriana. The pelage differs significantly from other southeastern woolly lemurs in that it is primarily light reddish brown on most of the body and grey under the jaw and on the extremities. The pelage is thicker on the head than other eastern woolly lemurs.
Peyrieras's woolly lemur or Peyrieras's avahi is a species of woolly lemur native to southeastern Madagascar. It weighs about 1 kg.
Ramanantsoavana's woolly lemur, also known as Ramanantsoavana's avahi or the Manombo woolly lemur, is a species of woolly lemur native to southeastern Madagascar. It weighs about 1 kg. It was originally considered a subspecies of the southern woolly lemur, A. m. ramanantsoavana, but was elevated to a separate species in 2006 based on molecular, phenotypic and morphological data.
Arnhold's mouse lemur or the Montagne d'Ambre mouse lemur is a species of mouse lemur endemic to Madagascar. Its holotype was first collected on 27 November 2005, and was first described in 2008. According to genetic tests, it is genetically distinct from its closest sister taxa, the Sambirano mouse lemur.
Ludwig Lorenz von Liburnau was an Austrian zoologist. He was the son of naturalist Josef Roman Lorenz von Liburnau (1825–1911).
