Propithecus Tattersalli 001b
A sifaka (; ) is a lemur of the genus ''Propithecus'' from the family Indriidae within the order Primates. The common name 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 indriids 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 skillful climbers ...

Diurnal Animal
Diurnality is a form of plant and animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which preferred pollinator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silky Sifaka
The silky sifaka (''Propithecus candidus'') is a large lemur characterized by long, silky, white fur. It has a very restricted range in northeastern Madagascar, where it is known locally as the ''simpona''. It is one of the rarest mammals on Earth. The silky sifaka is one of nine sifaka species (genus ''Propithecus''), and one of four former subspecies of diademed sifaka (''P. diadema''). Studies in 2004 and 2007 compared external proportions, genetics, and craniodental anatomy supporting full species status, which has generally been accepted. The silky sifaka has a variable social structure, and lives in groups of two to nine individuals. It spends most of its day feeding and resting, though it also devotes a considerable amount of time to social behaviors, such as playing and grooming, as well as travelling. Females occasionally take priority over males during feeding. Like other eastern sifakas, it consumes mainly leaves and seeds, but also fruit, flowers, and even soi ...

Milne-Edwards's Sifaka
Milne-Edwards's sifaka (''Propithecus edwardsi''), or Milne-Edwards's simpona, is a large arboreal, Diurnal animal, diurnal lemur endemic (ecology), endemic to the Madagascar lowland forests, eastern coastal rainforest of Madagascar. Milne-Edwards's sifaka is characterized by a black body with a light-colored "saddle" on the lower part of its back. It is closely related to the diademed sifaka, and was until recently considered a subspecies of it. Like all sifakas, it is a primate in the family (biology), family Indriidae. The species' name honors French zoologist Henri Milne-Edwards (1800–1885). Conservation status Milne-Edwards's sifaka is categorized as endangered by the IUCN, and is listed in CITES Appendix I. As of 2008, there were estimated to be approximately 28,600 individuals left with only about 3,500 of those remaining in protected areas. It remains threatened by habitat loss, hunting and may be sensitive to a changing climate. Anatomy and physiology Milne-Edwards's ...

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. The woolly lemurs are the smallest indriids with a body size of and a weight of . 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 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, often consisting 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. Groups consisting of the mating pair and their offspring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus Propithecus Feet
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. 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 demonstrate both monophyly and validity as a separate lineage). # rea ...

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 the Madagascar ground boa and Malagasy ground boa. Description This species is included in the Boidae family of snakes, subfamily Sanziniinae. No subspecies are currently recognized. Adult females can be up to , males are typically smaller, the average size of the population is 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 of dorsal rhombs outlined with black or brown. Sometimes, this creates a vague zigzag impression. The sides are patterned with a series of black ovoid markings with reddi ...

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 the carnivora, carnivoran family Eupleridae. The fossa is the largest mammalian carnivore on Madagascar and has been compared to a small cougar, as it has Convergent evolution, 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 density, 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 f ...

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 being the prevention of resources being spent on weak or disabled offspring. Unwanted infants were usually abandoned to die of exposure, but in some societies they were deliberately killed. Infanticide is generally 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, Roman Empire, ancient Rome, the Phoenicians, ancient China, ancient Japan, Pre-Islamic Arabia, early modern Europe, Aboriginal Australians, Aboriginal Australia, Indigenous ...

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.
