寫完 Coquerel Sifakas (Lemurs), Tarsiers & Lorises 後, 心思思想睇吓另兩種類 Potto & Galagos 是什麼樣子的, 於是由上網找資料了.

Bushbaby (Galagos) :


Hahahahhhhhhhhhh!!!!! just 攪吓笑吧了.... 哈哈哈!!!

bush baby name for several small, active nocturnal primates of the loris family, found in forested parts of Africa. Bush babies, also called galagos, form the subfamily Galaginae. The smallest are about 1 ft (30 cm) long, including the long, furry tail. All have fluffy fur, small pointed faces with large eyes, and naked, highly mobile ears. The very large eyes are adapted for nocturnal vision and their pupils contract so as to be almost invisible. The long hind legs are specialized for jumping; the fingers and toes are long and slender, with fleshy terminal pads; and the thumb and big toe are opposable. Extremely swift and agile, bush babies leap like squirrels from branch to branch and hop on their hind legs on the ground. They feed on gums, insects, fruit, and vegetable matter. Senegal bush babies ( Galago senegalensis ) are familiar as pets. They are gregarious and spend much time grooming each other with their front teeth. Bush babies are classified in the phylum Chordata , subphylum Vertebrata, class Mammalia, order Primates, family Lorisidae.

Potto :

Perodicticus Potto

The potto is a mammal of the primate order and the prosimian suborder.
Physical Characteristics
The potto is 12 to 16 inches with a 1 1/2 to 6 inch tail. It weighs 1 3/4 to 3 /14 pounds. Its joints are very mobile and allow it to reach out at any angle to grasp branches. It has fur that may be gray, brown, or red. Its ears and eyes are small. Its body is slender and long.

Behavioral Characteristics
The potto is nocturnal, sleeping during the day. It is arboreal, living among the trees and is a careful but skilled climber. In order to escape the attention of predators, the potto has the ability to stay completely still for hours. If it is attacked, it tucks its head down and batters its attacker with a "shield" of horny skin that covers the spiny bones on the potto's upper back. Its slow movements, coloration, small size, use of little vocalization and the its nocturnal habits all also help protect the potto from predation.
Life Cycle
The potto's breeding season is yearlong; however, it usually occurs at such a time that the births will take place when fruit is most bountiful. Also, the breeding only occurs once per year. The gestation or pregnancy of the female potto lasts around 200 days. The one young suckles the mother's teats for 120 to 180 days or 4 to 5 months. The young potto becomes independent between 6 and 8 months. Both males and females become sexually mature at about 18 months old. The maximum lifespan of the potto is over 25 years.
Diet
The potto's diet consists of fruits, sap, gum and small animals. They eat more fruit then anything else in their diet. Species that have a fruit diet are often referred to as being frugivorous.
The potto is sometimes part of the diet of the African palm civet. However the African palm civet, like the potto is usually mostly frugivorous.
Habitat
The potto is located in western and central Africa. It lives in habitats of thick rainforest. It requires trees in order to survive.

The end.

在 Prosimians 下 的 Coquerel Sifakas ( Lemurs), Tarsiers  同Lorises 是我暫時覺得最可愛的, 所以要來紀錄一下:

Pygmy Slow Loris:

 

 

 

 

 

 

Key Facts

Adult Size : 0.8 - 1.0 pounds

Natural Range : Vietnam, Laos, and parts of Cambodia

Social life : Solitary nocturnal forager

Habitat : Secondary forests, formally in primary rainforests

Diet : Fruits, other vegetation, and occasional small mammals and birds

Lifespan : 20 years, observed in captivity

Sexual maturity : females 9 months, males 17 - 20 months

Mating : Once every 12 - 18 months

Gestation : 188 days

Number of young : 1 - 2 offspring every 1 - 1 ½ years

DLC Naming theme : Insect names (Grasshopper and Skimmer.)

Interesting Facts

• Pygmy lorises sleep rolled up in a ball with their head between their legs.
• Pygmy lorises often hang upside-down from branches by their feet so they can use both hands to eat.
• The native habitat of pygmy lorises was devastated during the Vietnam War. They are the most endangered of the non-lemur prosimians.
• Pygmy lorises are often sold in the markets in Vietnam.

續上篇 Coquerel sifaka
在 Prosimians 下 的 Coquerel Sifakas ( Lemurs), Tarsiers  同Lorises 是我暫時覺得最可愛的, 所以要來紀錄一下:

Tarsiers:

tarsier , small, nocturnal, forest-dwelling prosimian primate , genus Tarsius.
There are at least three species found in the Philippines, in Sumatra and Borneo, and in Sulawesi.
Tarsiers are about 6 in. (15 cm) long with a 10 in. (25 cm) hairless tail, and weigh about 4.5 oz (130 g).
The body is covered with dense brown fur. Enormous round eyes are set close together in a flat face.
Tarsiers' legs are specialized for climbing and jumping and end in long, thin digits bearing adhesive pads.
They feed on insects and reptiles.
They are believed to mate for life and to form family groups.
Tarsiers are classified in the phylum Chordata , subphylum Vertebrata, class Mammalia, order Primates, family Tarsiidae.

Coquerel Sifakas ( Lemurs) :

Habitat : northwestern dry deciduous forest
Diet : young leaves, flowers, fruit, bark and dead wood in the wet season, mature leaves and buds in the dry season
Lifespan : 25 - 30 years

Interesting Facts

• The Malagasy name 'sifaka' comes from the distinct call this animal makes: "shif - auk".
• The DLC houses the only breeding colony of Coquerel's sifaka.
• Our very own Jovian, a young male Coquerel's sifaka, is the star of the children's television show, Zoboomafoo.

to be continued………………………………

Laser scanners combined with a computerized photographic model produce a digital code of her body, which once processed creates an accurately 3D model.
 



Ida is a warm blood creature covered with thick fur, she is just under one meter long including her tail, which she used for balance as she scampered on all fours along the rain forest canopy, her opposable thumbs and toes gripped the branches.


Ida is probably activity at night, like us, her two large forward facing eyes gave her excellence stereoscopic vision.



How significant is she to our understanding of our evolution?  Does she belong on the evolutionary branch that leads to us???


The Eocene period in which she lived was a crucial time in the history life, without the developments that happened we will not exists now.

At some point during this new dawn, the primates split into two major groups.
The Prosimians (the non human branch) which still survive today, mainly as a modern lemurs.
The other branch the Antropoides has developed into monkeys, apes and ultimately us - humans.



The advantage of having a skeleton that is so completed, hopefully will let us make the connection to what came later.   In the sense, studying primate evolution is all about looking at the diversity living today and tracing that back through time.  What we are interested here to see is how apes & monkeys traced back, how lemurs traced back and which of these or all of them can we find in the Eocene.
 


The first guess of cause, because of the other specimen that were found in the Messel locality, of course is to say that this is a primitive lemur.



Most lemurs are of the size of monkeys, they have similar habits and life styles, but they are evolutionary side branch, they hardly changed fundamentally in 47 million years.


Prosimians species : Lemurs, Tarsiers, Loris, Galagos, & Pottos



Lemurs : Coquerels sifaka





Ring-tailed lemur




Lemurs second digit has a long grooming claw, on the hind foot.


Lemurs are using this for groom their fur.


Checking their teeth


Their front teeth in the lower jaw are a tooth comb.

 


Ida does not have a tooth comb and no grooming claw, she only has nails like humans.  Ida does not belonging to the lemurs.
