Propithecus Candidus 001
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. Anatomy and physiology Sifakas are medium-sized indrids with a head and body length of and a weight of . Their tail is just as long as their body, which differentiates them from the Indri. Their fur is long and silky, with coloration varying by species from yellowish-white to blackish-brown. Their round, hairless face is always black. As with all lemurs, the sifaka has special adaptations for grooming, including a toilet-claw on its second toe and a toothcomb. Sifakas move by vertical clinging and leaping, meaning they maintain an upright position leaping from tree trunk to tree trunk and moving along branches. They are skillfu ...

Edward Turner Bennett
Edward Turner Bennett (6 January 1797 – 21 August 1836) was an English zoologist and writer. He was the elder brother of the botanist John Joseph Bennett.Bennett, Edward Turner (1797-1836), zoologist by J. C. Edwards in Dictionary of National Biography online (accessed 21 July 2008) Bennett was born at Hackney and practiced as a surgeon, but his chief pursuit was always zoology. In 1822 he attempted to establish an entomological society, which later became a zoological society in connection with the |
Toilet-claw
A grooming claw (or toilet claw) is the specialized claw or nail on the foot of certain primates, used for personal grooming. All prosimians have a grooming claw, but the digit that is specialized in this manner varies. Tarsiers have a grooming claw on second and third toes. In the suborder Strepsirrhini, which includes lemurs, galagos and lorises, the grooming claw is on the second toe. Less commonly known, a grooming claw is also found on the second pedal digit of night monkeys (''Aotus''), titis (''Callicebus''), and possibly other New World monkeys. The first toe is the large one, the equivalent of a human big toe. However, in all these prosimians the foot is more or less hand-like. The first toe is opposable, like a human thumb, and the second and third toes correspond approximately to the index and middle fingers. Like a claw or a nail, the grooming claw is also made of keratin Keratin () is one of a family of structural fibrous proteins also known as ''scleroproteins ...

Woolly Lemur
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. With a body size of and a weight of , the woolly lemurs are the smallest indriids. Their fur is short and woolly. The body can be grey brown to reddish, with white on the back of the thighs, with a long, orange tail. The head is round with a short muzzle and ears hidden in the fur. Woolly lemurs can be found in both humid and dry forests, spending most of their time in the leafy copse. Like many leafeaters, they need long naps to digest their food. Woolly lemurs live together in groups of two to five animals, which often consist of parents and several generations of their offspring. Like all indriids, the woolly lemurs are strictly herbivorous, eating predominantly leaves, but also buds and, rarely, flowers. Males and females live in pairs. Although likely, the presence of extrapair cop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus Propithecus Feet
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Madagascar Ground Boa
''Acrantophis madagascariensis'' is a species of boid snake in the subfamily Sanziniinae that is endemic to the island of Madagascar. Its common names include Malagasy ground boa and Madagascar boa. Description This species is included in the Boidae family of snakes, subfamily Sanziniinae. No subspecies are currently recognized by ITIS. Adult females can be up to 10 feet (3.05 metres), males are typically smaller, the average size of the population is 8 feet (2.44 m) in length.Mehrtens JM. 1987. ''Living Snakes of the World in Color''. New York: Sterling Publishers. 480 pp. . This is the largest snake species found on the island of Madagascar. ''Acrantophis madagascariensis'', like others in the family, dispatch their prey by constriction. The color pattern consists of a pale reddish-brown ground color mixed with gray, overlaid with a pattern dorsal rhombs outlined with black or brown. Sometimes this creates a vague zigzag impression. The sides are patterned a series of black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossa (animal)
The fossa (''Cryptoprocta ferox''; or ; ) is a slender, long-tailed, cat-like mammal that is endemic to Madagascar. It is a member of Eupleridae, the family of carnivorans, and closely related to the Malagasy civet. The fossa is the largest mammalian carnivore on Madagascar and has been compared to a small cougar, as it has convergently evolved many cat-like features. Adults have a head-body length of and weigh between , with the males larger than the females. It has semi-retractable claws (meaning it can extend but not retract its claws fully) and flexible ankles that allow it to climb up and down trees head-first, and also support jumping from tree to tree. A larger relative of the species, ''Cryptoprocta spelea'', probably became extinct before 1400. The species is widespread, although population densities are usually low. It is found solely in forested habitat, and actively hunts both by day and night. Over 50% of its diet consists of lemurs, the endemic primates found o ...

Infanticide
Infanticide (or infant homicide) is the intentional killing of infants or offspring. Infanticide was a widespread practice throughout human history that was mainly used to dispose of unwanted children, its main purpose is the prevention of resources being spent on weak or disabled offspring. Unwanted infants were normally abandoned to die of exposure, but in some societies they were deliberately killed. Infanticide is now widely illegal, but in some places the practice is tolerated or the prohibition is not strictly enforced. Most Stone Age human societies routinely practiced infanticide, and estimates of children killed by infanticide in the Mesolithic and Neolithic eras vary from 15 to 50 percent. Infanticide continued to be common in most societies after the historical era began, including ancient Greece, ancient Rome, the Phoenicians, ancient China, ancient Japan, Aboriginal Australia, Native Americans, and Native Alaskans. Infanticide became forbidden in Europe and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Brown Lemur
The common brown lemur (''Eulemur fulvus'') is a species of lemur in the family Lemuridae. It is found in Madagascar and has been introduced to Mayotte. Taxonomy Five additional currently recognized species of lemur were until 2001 considered subspecies of ''E. fulvus''. These are: *White-fronted brown lemur, ''E. albifrons'' * Gray-headed lemur, ''E. cinereiceps'' * Collared brown lemur, ''E. collaris'' * Red-fronted brown lemur, ''E. rufus'' * Sanford's brown lemur, ''E. sanfordi'' However, a number of zoologists believe that ''E. albifrons'' and ''E. rufus'' should continue to be considered subspecies of ''E. fulvus''. Physical description The common brown lemur has a total length of , including of tail. Weight ranges from . Common brown lemurs are unique amongst ''Eulemur'' in that they exhibit little-to-no sexual dichromatism: in both males and females, the face, muzzle and crown are dark gray or black, with white or tan "cheeks" of varying thickness.

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 .

Herbivore
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 '' Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ''her ...
