Ringtailed Coati



The ringtailed coati (Nasua nasua) is an omrnivore from the family Procyonidae.  Ringtailed coatis are small raccoon-like animals found in South America.  It rated as Least Concern by IUCN.


Physical Features
The ringtailed coati measures about 67 cm (26 inches) excluding the tail.  The tail measures 69 cm (27 inches).  Males are generally bigger than females.  They have a shoulder height of 30 cm (12inches).  Ringtailed coatis have stocky bodies, which can range from reddish brown to black.  They have very long and banded tails.  Their snout is flexible and long, which enables them to catch insects like earthworms and millipedes that live inside the soil.  Its fur has coarse and long hair.  They have a life span of 17 years in captivity and 5 to 9 years in wild.  Ringtailed coatis can weigh 6 kilograms


Diet
The ringtailed coati is an omnivore eating woodland insects like millipedes and earthworms.  To catch these soil inhabiting creatures, ringtailed coatis use their long and flexible snout to search and catch them.  Adult and large males try to catch bigger prey like other rodents.  ringtailed coatis sometimes catch frog and lizards with their forepaws.  They are very fond of fruit.


Distribution and Habitat
The ringtailed coati is found in South American countries like Argentina, Colombia, Venezuela, Peru, Ecuador, Brazil and Uruguay.  They live in woodlands.


Behavior
Ringtailed coatis are active throughout the day.  Females often make groups with their young while males are solitary.  They produce grunts and chittering noises to contact with group members.  When they are threatened, they will bark.


Conservation Status
The ringtailed coati considered as least concern.  They are very abundant and quite widespread.  Their population must be several thousands.

Siamang



The siamang (Symphalangus syndactylus) is a species of gibbon only in Malaysia, Thailand and Sumatra.  It is one of the largest gibbons and has a large throat sac which it uses to make loud calls.  It is currently protected by law.


Physical Features
Siamangs are the largest of the the gibbons, measuring 90 cm (35 inches) and weighing 13 kilograms.  Both males and females have large throat sacs.  It can sometimes be twice the size of other gibbons.  Siamangs have a height of 3.3 feet ( 1 meter).  Their throats sacs are called gular sacs.  They have two digits on each foot which are partially joined with a membrane.  They can inflate their throat sacs to the size of their heads.  They have black fur and have a very long hand which is shaped like a hook at the end.  They have a life span of 30 years.


Diet
Siamangs spend about 5 hours in a day eating.  They are omnivores, eating insects, fruits, invertebrates and leaves.  Half of their diet is made up of leaves.  Siamangs always hang on a tree with one hand while feeding.  They feed on about 160 species of plants.


Behavior
Siamangs spend 50 % of their time in resting.  Siamang pairs may start their first day with a duet led by the female and with the male giving melody support.  This singing (which is like shrieking in different tunes) even acts like a territorial display.  Siamangs can give loud and deafening shrieking calls with their large throat sac.


Distribution and Habitat
Siamangs are found in the rainforests of Malaysia, Thailand and Sumatra


Population and Threats
In 1990, there was an estimated population of 360,500 individuals in the wild found in Indonesia.  In Sumatra's (Indonesia) third national park, Bukit Barisan Selatan National Park, the population was 22,390 individuals according to 2002.  Even though hunting hunting primates for meat in Indonesia is banned (unlike other part of Asia) they are threatened due to forest fires and illegal logging.  In Malaysia and Thailand, infants are taken for illegal pet trade.  Their mothers are killed as they are highly protective of their young and will be very difficult to separate the infants and their mother.

Diet
Bateleurs can eat mammals about the size of a baby antelope.  They may even eat birds like ground birds and reptiles like snakes and lizards.  Sometimes, they eat dead meat if available.  Bateleurs hunt alone in the air but sometimes, large numbers may eat together.


Distribution and Habitat
Bateleurs line in open woodland and savannas.  The bateleur is found in much of Africa.  It is mainly found in places south of Sahara desert.  Its distribution ranges extends to northern Namibia and South Africa but is not found in dense forests of places around the equator.


Life Cycle
Bateleurs build stick nests on big trees and generally one egg is produced by the female.  Bateleurs build their nests near rivers.  The eggs incubate for about 59 days and the young fledge after 100 days.


Conservation Status
Bateleurs are not endangered, but they are decreasing in numbers especially in the south.  This is because of habitat loss and hunting.

Proboscis Monkey



The proboscis monkey (Nasalis larvatus) is a species of Old world monkey found in Borneo.  They are arboreal and will only come down from tree tops to search for food.  They are endangered due to loss of habitat.


Physical Features                                                      
The nose of a proboscis monkey
The proboscis monkey is well known for its long nose.  It got its name from the long nose it has, which can grow about 7.5 cm.  Males are larger than female.  Males can weigh about 25 kilograms.  Generally, adults can measure about 70 cm (28inches) from nose to tail.  Females also have a large nose as compared to other species of monkeys but males have larger ones.  Males use their large nose to attract females during mating season.   When agitated, the nose of these monkeys swell with blood.  Adult proboscis monkeys have reddish brown fur and grayish limbs while young ones have a blue face ad blackish fur with a normal sized nose.


Diet
The proboscis monkey is an omnivore.  If it needs to eat a  fruit, it will only eat and unripe one as the sugar in ripe fruits is not good for its digestive system and therefore can be fatal.  Their diet consists of seeds, fruits, leaves, mangrove shoots and insects.


Ecology
The proboscis monkey is arboreal and can even swim very well.  They swim from island to island.  While swimming, they keep their body upright and carry their young ones on their hips.  Proboscis monkeys live in groups called bands.  There are many troops seen walking upright continuously.


Distribution and Habitat
The proboscis monkey is only found on the island of Borneo.  They live in mangrove forests, riparian lowland forests and swamps.


Conservation Status
The proboscis monkey is rated as endangered by the IUCN.  It is believed that there are only 1000 individuals left.  Its numbers have decreased due to habitat loss and hunting.  In 1977, there were about 6500 individuals.  That population decreased to about 1000 in 2006.  They are currently protected by law and are found in 16 different wildlife sanctuaries.  These sanctuaries are:Gunung Pueh Forest Reserve, Gunung Palung National Park, Kendawangan Nature Reserve, Kutai National Park, Lesan Protection Forest, Muara Kaman Nature Reserve, Mandor Reserve, and Tanjung Putting National Park in Indonesia; Bako National Park,Danau Sentarum National Park , Kabili-Sepilok Forest Reserve, Klias National Park, Kulamba Wildlife Reserve, Lower Kinabatangan Wildlife Sanctuary, Sungei Samunsam Wildlife Sanctuary and Ulu Segama Reserve in Malaysia.

A quokka eating in a zoo
The quokka is a herbivore, eating shrubs, grass and different types of leaves.  In the western part of Rottnest island, when there is less water, quokkas will eat leaves from succulent plant in order to get enough water.


Distribution and habitat
The quokka is found only on the islands of Rottnest and Bald.  They mainly live on these two islands because of introduced predators such as foxes are not found on these islands.  Quokkas inhabit thick forests, open woodland, low scrub and swamp edges where available.


Conservation Status
The quokka is rated as vulnerable by IUCN.  They can be found roaming on the Rottnest island near their stronghold.  They are decreasing in numbers due to habitat loss prosecution.  Quokkas are popular tourist attractions.  Sometimes, tourists will feed these animals but, modern foods might upset the animal's digestive system.

Aye-Aye



The aye-aye (Daubentonia madagascariensis) is a species of lemur found in Madagascar and is a strepsirrhine primate.  It is rated as critically endangered.  It is the only extant species of the genus Daubentonia and the family  Daubentoniidae.  The other species from this family and genus got extinct about 1000 years ago.  Scientists are not sure if this animal should be classified under the squirrel or lemur family.


Physical Features
The aye-aye is mostly dark brown or black in color.  It has a very bushy and long tail.  They are the world's largest nocturnal primate.  They have rodent like teeth and a very thin middle finger which they use to look for grubs in tree barks.  Aye-ayes have long claws on all toes and fingers, except for their two big toes.  These long claws help in dangling on tree branches.  Their tails grow about 61cm long while their body length, excluding the tail, is 43cm.  Aye-ayes can weigh about 2 kilograms.  An aye-aye is the size of a house cat.  They have big eyes so that they can see in dark and they even have very sensitive ears.  They might not look like primates at all but, they are closely related to human, apes and chimpanzees.  The aye-ayes long middle finger is known to move back and forth at speeds of 3 strokes per second.
Diet
The aye-aye is an omnivore, eating nuts, grubs, nectar, fruits, seeds and some types of fungi.  The aye-ayes has a very different style of feeding.  It taps on the tree to search for grubs.  Once it finds a grub, it will gnaw a hole inside the tree and then insert its long middle finger to remove the grub.  It is also the only primate to find food with the help of echolocation.


Distribution and Habitat                                                        Range of Aye-Aye
The aye-aye is found only in Madagascar.  It mainly lives in the east coast of Madagascar and lives in rainforests or deciduous forests.  Due to deforestation, many ayes-ayes live in cultivated areas.  Aye-ayes will mostly be spotted in canopies of forests.  In the day, these animals will rest in nests built and tree branches.


Conservation Status
The aye-aye is critically endangered due to heavy poaching and removal of rainforests and deciduous forests.  They are mainly hunted as many people think aye-ayes are a bad omen and therefore ruthlessly killed.  Now, they are protected by law.

Geoffroy's Spider Monkey


The geoffroy's spider monkey (Ateles geoffroyi) is a species of spider monkey which is mostly found in Central America, Mexico and very few parts of Colombia.  It is also known as the black handed spider monkey.  They are endangered and is also extinct in some parts of its range.


Physical Features                                                 The tails help in balancing                                                                                                                      
The geoffroy's spider monkey has a body length of about 60    centimeters and weighs about 9 kilograms which makes it one of the largest New World Monkey.  Its tail is longer than the body, measuring about 85 centimeters.  They have very thin arms and legs.  The arms are about 25% longer than the legs.  The body color varies according to the subspecies like red, buff, rust, brown and black.  Males are slightly larger than females.  Geoffroy's monkeys have thumbless arms which makes brachiation.  Females have an organ called the clitoris, which is large and protrudes, looking like a penis.  It looks like a males penis which is why many scientists have mistaken a female for a male.  They have a prehensile tail which helps them th balance thier body while they jump from one tree to another.


Distribution
The geoffroy's spider monkey is found in many parts of Centrals America.  The countries it is found are Nicaragua, Guatemala, Panama, Costa Rica, Honduras, El Salvador and Belize.  It is also found in some parts of Mexico and Colombia.  They are found in rainforests, even semi deciduous forests and mangroves.


Diet
The geoffroy's spider monkey mostly eats fruits.  They spend about 80 % of their time eating fruits and leaves.  Leaves are also important in their diet as it gives protein which is not present in fruits.  They also eat flowers, barks, honey and insects.


Conservation Status
The geoffroy's spider monkey is endangered.  They are endangered as they are captured for pet trade and are also hunted.  Geoffroy's spider monkey is endangered mainly because of habitat loss as it needs a large space to live due to its big size.

The common chimpanzee (Pan troglodytes) one of the two species of the genus Pan.  The common chimpanzee is also known as the Robust chimpanzee.  It is a type of great ape and is endangered due to habitat loss and poaching for bushmeat.


Physical Features
Common chimpanzees have black hair covering their full body except for their fingers, toes, face, sole of their feet and their palms.  They have a gestation period of eight months and have a life span of 50 years in captivity.  The arrangement of their toes and fingers allow them to grasp branches and other items strongly.  Females are smaller than males, measuring about 4.5 feet while males measure about 5.8 feet.  Normally, adult common chimpanzees weigh from 45 kilograms to 65 kilograms.


Diet
Common chimpanzees are herbivores though, many of the are omnivores as they eat meat as well as vegetation.  Most of the common chimpanzees diet consists of seeds, fruits, nuts,
Chimpanzee family in Taronga zoo.
tubers and some populations also eat termites.  Common chimpanzees sometimes even eat Western red colobus monkeys.  Cannibalism has been recorded in minute populations.  Common chimpanzees spend eight hours a day eating.   The West African chimpanzee is the only animal besides humans to make specialized weapon for hunting.  In Sengal, it was observed that the west african chimpanzee makes hunting tools by ripping tree limbs from trees, taking their bark out and then sharpen one edge with their teeth to make a spear.  They use these spears to kill sleeping galagos in their hollow.



Distribution
The common chimpanzee if found in African countries like Cameroon, Democratic Republic of the Congo (Zaire), Gabon, Equatorial Guinea, Mali, Republic of Congo, Nigeria, Sierra Leone, Côte d'Ivoire, Ghana,  Liberia, Central African Republic, Rwanda, Zambia, Tanzania, Burundi, Sudan and Uganda.


Conservation Status
The common chimpanzee is an endangered species like its relative, the bonobo.  It is endangered due to habitat loss and hunting for bushmeat.  There are many breeding programs around the world to protect this threatened species.
