Baboon monkeys

Baboons are African and Arabian Old World monkeys belonging to the genus Papio, part of the subfamily Cercopithecinae. There are five species, which are some of the largest non-hominid members of the primate order; only the mandrill and the drill are larger. Previously, the closely related gelada (genus Theropithecus) and the two species (mandrill and drill) of genus Mandrillus were grouped in the same genus, and these Old World monkeys are still often referred to as baboons in everyday speech. They are P. ursinus (chacma baboon, found in southern Africa), P. papio (western, red, or Guinea baboon, found in the far western Africa), P. hamadryas (hamadryas baboon, found in the Horn of Africa and south-western Arabia), P. anubis (olive baboon, found in the north-central African savanna) and P. cynocephalus (yellow baboon, found in south-central and eastern Africa). Many authors distinguish P. hamadryas as a full species, but regard all the others as subspecies of P. cynocephalus and refer to them collectively as "savanna baboons". This may not be helpful: it is based on the argument that the hamadryas baboon is behaviorally and physically distinct from other baboon species, and that this reflects a separate evolutionary history.
Their diet is omnivorous, but mostly vegetarian; yet they eat insects and occasionally prey on fish, shellfish, hares, birds, vervet monkeys, and small antelopes. They are foragers and are active at irregular times throughout the day and night. They can raid human dwellings and in South Africa they have been known to prey on sheep and goats.

Their principal predators are humans, the lion, both the spotted and striped hyena and the leopard. They are however considered a difficult prey for the leopard, which is mostly a threat to young baboons. Large males will often confront them by flashing their eyelids, showing their teeth by yawning, making gestures, and chasing after the intruder/predator.
The structure within the troop varies considerably between hamadryas baboons and the remaining species, sometimes collectively referred to as savanna baboons. The hamadryas baboon often appear in very large groups composed of many smaller harems (one male with four or so females) to which females from elsewhere in the troop are recruited while they're still too young to breed. Other baboon species have a more promiscuous structure with a strict dominance hierarchy based on the matriline. The hamadryas baboon group will typically include a younger male, but he will not attempt to mate with the females unless the older male is removed.

Baboons can determine from vocal exchanges what the dominance relations are between individuals.

Baboon mating behavior varies greatly depending on the social structure of the troop. In the mixed groups of savanna baboons, each male can mate with any female. The mating order among the males depends partially on their social ranking, and fights between males are not unusual. To garner this friendship, they may help groom the female, help care for her young, or supply them with food. The probability is high that those young are their offspring. Some females clearly prefer such friendly males as mates. However, males will also take infants during fights in order to protect themselves from harm.

A female initiates mating by presenting her swollen rump to the male. But "presenting" can also be used as a submissive gesture and is observed in males as well. This submissive gesture has many unspoken meanings amongst the troop.

Aye Aye pictures and life info

aye-aye is a lemur, a strepsirrhine primate native to Madagascar that combines rodent-like teeth and a special thin middle finger to fill the same ecological niche as a woodpecker. It is the world's largest nocturnal primate, and is characterized by its unusual method of finding food; it taps on trees to find grubs, then gnaws holes in the wood and inserts its narrow middle finger to pull the grubs out. The only other animal species known to find food in this way is the striped possum. It usually sticks to foraging in its own personal home range, or territory. The home ranges of males often overlap, and the males can be very social with each other. Female home ranges never overlap, though a male's home range often overlaps that of several females. The male aye-ayes live in large areas up to 80 acres (320,000 m2), while females have smaller living spaces that goes up to 20 acres (81,000 m2). Regular scent marking with their cheeks and neck is how aye-ayes let others know of their presence and repel intruders from their territory. The monkey-like body of the aye-aye enables it to move vertically with ease. It climbs trees by making successive vertical leaps, much like a squirrel. Horizontal movement is more difficult, but the aye-aye rarely descends to jump to another tree, and can often cross up to 4 km (2.5 mi) a night.[citation needed]
Infants are fully dextrous within a month of birth.
aye-aye lives primarily on the east coast of Madagascar. Its natural habitat is rainforest or deciduous forest, but many live in cultivated areas due to deforesting. Rainforest aye-ayes, the most common, dwell in canopy areas, and are usually sighted upwards of 700 meters altitude.
