Dogs are carnivorous mammals that have been experienced since the domestication of wolves 15,000 years ago  or may have since 100,000 years ago based on genetic evidence and fossil discoveries of DNA testing.  Another study revealed that dog domestication history not so long.   
The dog has developed into hundreds of races with different variations, ranging from the dog's height as several tens of centimeters Irish Wolfhound Chihuahua to a high of more than one meter. Dog coat color can be varied, ranging from white to black, also red, gray (often called "blue"), and chocolate. In addition, dogs have different types of fur, ranging from very short to the length can reach several centimeters. Dog hair can be straight or curly, and coarse-textured till soft as wool.
Dogs are social animals just like humans. Proximity patterns of human behavior makes a dog a dog can be trained, to play, to live with humans, and invited bersosialiasi with humans and other dogs. The dog has a unique position in the relationship between species. Loyalty and devotion that dogs indicated very similar to the human concept of love and friendship. Despite the dog's natural instincts as a group of animals, dog owners greatly appreciate the loyalty and devotion of dogs and regard it as their own family members. Dog often to be given the same family name as the name of the owner. In contrast, dogs think humans as members of the group. The dog just bit the distinguished position with fellow dog owners who are still one group, and often do not distinguish at all.
Cat, Felis silvestris catus, is a carnivore. The word "cat" usually refers to the "cat" which has been tamed, but can also refer to the "big cats" like lions, tigers, and tigers.
Cats have been mixed with human life since at least 6000 years BC, from a cat skeleton on the island of Cyprus. Ancient Egyptians from 3500 BC have been using a cat to keep mice or other rodents from the barn manyimpan crops.
Currently, the cat is one of the most popular pet in the world. Cat lineage officially registered as Purebred cats or pure (pure breed), such as Persian, Siamese, Manx, sphinx. Cats like this are usually bred in the animal care official. The number of cats race is 1% of all cats in the world, the rest were crossbred cats with a wild feline or cat home.
is a warm-blooded animals, have wings and fur covered bodies midrib. For birds, eagles breed by laying eggs that have hard shell in the nest she made. She keep her child to be able to fly.
The Eagle is a predator. The main food small mammals such as mice, squirrels and chickens. There are some who catch fish eagle as their main food. Not toothed hawk but has a strong bent to tear the flesh prey. This bird also has a pair of strong legs and sharp nails for gripping prey and sharp eyesight to hunt their prey from a distance.
The Eagle has a good respiratory system and are able to provide the amount of oxygen is much needed when flying. Eagle heart consists of four chambers like humans. Booth over is known as the atrium, while the lower chamber recognized as the ventricles.
The bear has a small tail, sense of smell and hearing are excellent, five nails per palm of the hand that can not be drawn in, and long hair, thick and rough. They have broad paws, long snout and rounded ears. His teeth are used for defense and tools and depending on the food. Nails are used to tear, dig, and catching. Pengelihatan bears almost the same as human pengelihatan. Black bears and the like, not color blind, which allows them to differentiate.
Depending on the species, bears can have 32 to 42 teeth. Bears no specialized teeth for killing prey mereka.Gigi bear fangs are relatively small and are generally used for self defense or a tool. Big bear molars, flat and used for cutting and grinding the plants into smaller pieces that can be digested.
The bear has four paws. Each paw has five sharp nails and long. Nails can be used to climb trees, tore termite nests and honeycomb, digging roots, or catch prey, depending on the species. Do not underestimate the bear, can run to reach speeds of 50 km / h (30 mph). Bear can also move with flexible and agile.
Bear fur long and rough. Coat color varies depending on the species. There is a white, blonde or beige, black and white, to black or brown all all. Bears fur color also varies, although they are one species. For example, black bears may be the American black, brown, reddish brown, or bluish-black. Some species, such as the sun bear and spectacled bear has a brightly colored chest with facial markings.
In all bear species, males larger than females. Differences between the sexes is, the greater the larger species. Male polar bears weigh two times larger than females, while the male species smaller bear almost equal weight females. Bears can live around 25 years to 40 years. Bears that live in the forest, die sooner than those who live in a zoo.
There are many different kinds of bears such as polar bears, brown bears, black bears, pandas, etc..
Crocodiles are large reptiles that live in water. Scientifically, including all species of crocodile tribe members Crocodylidae, including crocodile fish (Tomistoma schlegelii). However this name can also be worn loosely to refer to the 'crocodile' crocodiles, kaiman and gavial; the crocodile relatives of different tribes.
Crocodiles are generally inhabit freshwater habitats such as rivers, lakes, swamps and other wetlands, but some are living in such brackish water estuarine crocodile. Vera is the main food animals such as the backbones of fish, reptiles and mammals, sometimes prey on mollusks and crustaceans depends on the species. Crocodile is an ancient animal, which is only slightly changed because of evolution since the time of dinosaurs.
Known also several local names to refer to crocodiles, such as buhaya (Sd.); buhaya (bjn); middle-aged or pickpocket (Jw.; bicokok (Btw.), bekatak, or crocodiles frogs to mention small crocodile fat; senyulong, crocodile jolong-jolong (Mly.), or a crocodile-julung julung to mention the crocodile fish; crocodile pandanus, which is colored green crocodile; copper alligator, crocodile brownish yellow; and others.
In English crocodile known as cooking rice. The name comes from the Greek reference to the alligator they saw in the Nile, krokodilos; word formation stem from kroko word, which means 'gravel', and that deilos means 'worm' or 'people'. They call it 'worm rocks' because of the habit of observing alligators sunning on the banks of the river rocky.
Outside the ancient form, the crocodile is really a complex animal crawls. Not like usual reptiles, crocodiles have a four bears heart, diaphragm (diaphragm) and the cerebral cortex. On the other hand, shows the outer morphology clearly predatory aquatic way of life. Her body is "streamlined" allows him to swim faster. Crocodile folding legs attached to the back of his body, to reduce barriers and allow water to enhance speed while swimming. Toes webbed rear pool, which although not used as a driving force when swimming fast, the membrane is very useful when he had to suddenly turn around or make sudden movements in the water, or to start the swim. Webbed feet is also an advantage when the crocodile to move or walk in shallow water.
Crocodiles can move very quickly in short distances, even out of water. It has a very strong jaws that can bite with great force, making it an animal with the power of the biggest bite. This crocodile bites pressure not less than 5,000 psi (pounds per square inch; equivalent to 315 kg / cm ²) , compared with the power of the rottweiler dog bites only 335 psi, great white shark for 400 psi, or a hyena (hyena) around 800 to 1000 psi. Crocodile teeth pointed and sharp, very useful for holding prey. Crocodile attack prey by biting its prey and pounce on it, then pull firmly and abruptly into the water. Therefore, the muscles around the jaw so well developed that can be closed with a very strong. Which has shut the mouth as well as very difficult to open, similar to the gecko bite. On the other hand, the muscles that function to open the crocodile's mouth is very weak. The researchers simply wrapped crocodile large adhesive tape (duct tape) several times, or tie a rubber inner tube in the closed end of the muzzle, to keep her mouth shut while it was still carried out observations and measurements, or when to transport the animal safely. Alligator claws and nails were strong and sharp, but very stiff neck so that the crocodile is not so easy to attack sideways or backwards.
Crocodiles prey on fish, birds, mammals, and occasionally other alligators are also smaller. These reptiles are an ambush predator, he waited for the prey of terrestrial animals or fish over, and then pounce with a sudden. As cold-blooded animals, these predators can survive long enough without food, and seldom really need to move to hunt for prey. Although seemingly slow, crocodiles are top predators in their environment, and some species have been observed attacking and killing sharks.  is a bird kettle exception of Egypt, which is known to have a symbiotic relationship with crocodiles. It is said that these birds usually eat kettle animal parasites that live in the mouth of a crocodile, and for that the king of the river opens her mouth wide and let the pot go clean it.
is a ruminant mammal (ruminan) which includes family Cervidae. One characteristic is the presence of deer antler (deer horn), and not a horn, which is a bone growth that develops every year (usually in summer), especially in male deer (although there are some exceptions). There are approximately 34 species of deer in the world which is divided into two major groups: a group of old world deer including Subfamily Muntiacinae and Cervinae; and the new world deer, Hydropotinae and Odocoilinae.
Tiger or tigers belong in the animal kingdom phylum kordata (has a spinal cord), sub-phylum vertebrates (vertebrates), class of mammals (warm-blooded, furry with mammary glands), meat eaters (carnivores), the family Felidae (cat), Panthera genus, species tigris (tiger).
Tigers normally hunt large prey such as deer rather sambar, deer, pigs, deer, mouse deer, but will hunt small animals like hedgehogs when a rather large prey were not there.
The tiger is known as the largest cat, the tiger is basically similar to the lion in size, although a bit heavier. Different subspecies of tiger have different characteristics as well, in general male tigers weigh between 180 and 320 kg and females weigh between 120 and 180 kg. The length of males between 2.6 and 3.3 meters, while females between 2.3 and 2.75 meters. Among the living subspecies, Sumatran tigers are the smallest and the Siberian tiger most.
In most tiger stripes varies from brown to black. The shape and density of different lorengnya subspecies of one another, but almost all the tigers have more than 100 stripes. Javan tiger is now extinct may have stripes of even more. A unique pattern of each tiger's stripes, and can be used to distinguish one another, similar to the function used fingerprints to identify people. This is not, however, the recommended method of identification, difficulties related to recording the pattern of stripes on wild tigers. It seems the function of camouflage is to camouflage, to hide them from prey.
There are nine subspecies of tiger in the genus Panthera. Six of them were still alive today. The three remaining subspecies of tigers have been officially deemed extinct. Subspecies are still alive
* Indochina tiger (Panthera tigris corbetti) - contained in the rain forest and meadow Malaysia, Cambodia, China, Laos, Myanmar, Thailand, and Vietnam.
* Bengal tiger (Panthera tigris tigris) - located in the rain forests and grasslands of Bangladesh, Bhutan, China, India, and Nepal.
* South China tiger (Panthera tigris amoyensis) - who live in rain forests and grasslands central and western China.
* Siberian tiger (Panthera tigris altaica) - or also known as the Amur, Ussuri, Northeast China tiger, or Manchurian tiger. Siberian tigers live in rain forests and grasslands of China, North Korea, and Central Asia in Russia.
* The Sumatran tiger (Panthera tigris sumatrae) - who live only on Sumatra island.
* Malayan tiger (Panthera tigris jacksoni) - who lived only in Peninsular Malaysia.
 Subspecies are already extinct
* Caspian tiger (Panthera tigris virgata) - an extinct around 1950. This Caspian tiger once roamed the rain forests and grasslands of Afghanistan, Iran, Mongolia, Turkey, central Asia and Russia region.
* Javan tiger (Panthera tigris sondaica) - an extinct around 1972. Javan tiger once roamed the rain forests of Java, Indonesia.
* Bali tiger (Panthera tigris balica) - an extinct around 1937. Bali tiger once roamed the rain forest islands of Bali, Indonesia.
