  Animal is in a large class of biological world. Inorganic synthesis of organic compounds generally can not be only to organic matter (plants, animals or micro-organisms) for the Si Liao, so have the different forms of plant structure and physiological function, for feeding, digestion, absorption, respiration, circulation, excretion, sensation, life activities such as movement and reproduction. Zoological classification of animals under natural animal form, the internal body structure, the characteristics of embryonic development, physiological habits, living environment, geographical features, will feature the same or similar animal in the same category. A chordate, and two non-chordate categories.
  Species
  Vertebrates, including: fish, reptiles, birds, amphibians, mammals and other top-five network categories.
  Invertebrates, including: protozoans, mollusks, worms, insects, crustaceans and other categories. So all the invertebrate animals of the world for more than 90 percent.
  Fish features: aquatic animals (they can only live in water). Skin covered by scales, are cold-blooded animal. With fins (you can swim in water), with the gills of the cold-blooded animal. IVF. Mostly oviparous, some of viviparous and ovoviviparous.
  Many fish species, divided into two categories cartilaginous example: shark
  Feature: Skin tough, a very small Dun scales, no swim bladder, caudal fin up and down asymmetry. Have five pairs of gills, not gills. Bony class example: Opsariichthys features: bone to bone, skin has many mucus glands, bone scales covered. have swim bladders. reptilian features: terrestrial animals. skin covered with scales or scutellum. a waterproof jacket, water loss. is a cold-blooded animal (by the outside temperature or heat source to change its body temperature). mainly distributed in the Earth warmer areas.
  In vivo fertilization, oviparous or ovoviviparous. In the land to lay eggs, egg shell with waterproof package.
  Classification of reptiles testbyfindwo
  A full class
  Example: turtle
  Features:
  Had a hard shell. On the chin does not have teeth, but horny sheath. Oviparous. Divided into terrestrial, aquatic or marine life.
  Not enough class
  Example: Cobra
  Features:
  No limbs, shoulder straps, and sternum. Do not face and eyes with activities outside the ears. Tongue end of the fork, telescopic strong. Skin scales, body diameter than they can swallow large prey. All the organs of the snake-shaped growth of specialization, the left pulmonary degradation. snakes will regularly shed in order to facilitate growth.
  Birds
  Features:
  All wearing a feather, the body was streamlined, with horny beak.
  Eye in the sides of the head, neck long and flexible and turn 270 degrees.
  Forelimbs into wings special, hind legs with squamous skin, with four toes.
  Blooded animals (physiological processes through their own heat, even if the outside temperature is low, they can maintain a high and constant body temperature). The average temperature is about 10 degrees higher than in mammals (average 42 degrees).
  Oviparous.
  Classification of birds
  1. Main Features
  (1) surface is feathered, winged and can fly. Skin thin and soft, easy to strenuous exercise muscles.
  (2) metabolism, body temperature constant. High and constant body temperature, to promote the body metabolism rate. Temperature reduced the dynamic
  Material dependence on the external temperature conditions, access to capacity and night activities on the polar continent ability to survive.
  (3) has well-developed nervous system and sensory. Bird brain, cerebellum, midbrain are developed. Large cerebral hemispheres, which the Lord
  If the bottom of the striatum as the brain increases. In birds, the striatum is to manage the movement of senior positions, but also, and some of the complex health
  Living habits related. Experimental results show: removal of part of the striatum of birds, it's normal excitation and inhibition was destroyed by the visual
  Effects of mating, nesting and other habits of the loss. Birds of the cerebral cortex is not developed, well-developed cerebellum, which is movement of birds flying
  Related to coordination and balance.
  (4) has a better reproduction and behavior (nesting, incubation and brood).
  3. Classification of Aves
  (1) flat chest Head
  Main features are: strong hind legs, chest flat,
  Not keeled, non-flying capacity; feather distribution of all
  Body, no feathers and bare area of the sub-district, Yu-chi is not a small feather
  Hook, which does not form a pinna. Common species are ostrich,
  See chicks.
  (2) Penguin Head
  Diving life, the large birds, with a range of features to adapt to life in diving. Fin-like forelimbs, suitable for the water. With scales
  Flake feathers (rachis short _set_, narrow pinnae), uniformly distributed in the body surface. Short tail, short legs and the body moved to the rear, toes a bun,
  Adapt to swimming life. Walking on land the body nearly vertical, about Swinging. Developed subcutaneous fat is beneficial in cold regions and
  Water to maintain body temperature. Heavy bones and not inflated. Protruding sternum with well-developed keel, which with the water related. Swimming fast.
  The present distribution is limited to the southern hemisphere. On behalf of king penguins.
  (3) sudden chest Head
  Wings usually well developed, good at flying, breaking the keel up, the last 4 to 6 caudal end of the healing as a comprehensive bone. Generally have sufficient
  Gas bone, is well-developed feathers, constitute pinna, a feather surface area, divided into bare areas. Most non-mating male organ.
  The overall objective of a wide variety of birds, in order to study, it can be discussed from two aspects of their groups.
  One aspect is based on ecological types are divided into Natatores, wading birds, quail chickens, doves, climbing birds, birds of prey and songbirds seven ecological types.
  Natatores: Hui flat wide or long and pointed, short legs with webbed wings stronger or degradation.
  Waders: Hui thin and long, feet and toes are very long, webbed developed, powerful wings.
  Gallinarum: picks short and strong, strong feet and claws, wings short round.
  Dove: Hui short, the base of a wax film, short foot health, well-developed wings.
  Climbing birds: Hui rigidity, short enough health, and tapered, more developed wing.
  Raptor: Hui was a strong hook, enough strong, curved claws sharp hooks, good flying wing strong.
  Songbird: Hui different shape, foot short, thin, wing more developed.
  Another aspect is based on morphological characteristics is divided into a number of projects for research. Here are some common purpose.
  Pelecaniformes: 4 forward, a fine room with a full pop; nozzle end into a hook, a well-developed throat sac, nestling into the birds are late, travel poultry,
  Such as cormorants.
  Gruiformes: cervical length, bill length, leg length, toe the previous three, four toes in the same plane, the chicks are late into the Ukraine, waders,
  Egrets and other species are common.
  Anseriformes: flat mouth, a mouth with thick, the edge of a comb-like protrusions; backward short leg, toe, after three previous, pre-toes with webbed

  Falconiformes: mouth with Lee hook, claw well-developed flight resistant; visual acuity, raptors, chick late adults. Common species are
  Kite, kestrel, golden eagle, etc..
  Galliformes: strong body; Hui short, conical; wings short round, good to go; the male head has Rouguan, bright plumage; breeding
  Complex behavior, quail chicken, chicks are back into a bird. Such as the Brown Eared Pheasant, Golden Pheasant, etc..
  Gruiformes: bill length, neck length and leg length, three front and rear toe, toes webbed developed, the higher position after the toe with students, and the other three
  Toe not in the same plane, the chicks as early as birds, waders. Common species are red-crowned crane, gray crane and so on.
  Columbiformes: the mouth is short, with a wax film; four toes in the same plane on a short foot health, good walking; crop development, nestling birds as late as
  Or early adult birds, doves class. Common species are the original pigeon, Sandgrouse and other.
  Strigiformes: mouth hook claw strong and curved; first big eyes big move, the eye formation of facial disc feathers; ears large, with ear tufts, hearing
  Sharp; Fourth Division to reverse backwards; chicks belonging to the late adult birds, are birds of prey. Main species are Long-eared owl, flammeus so.
  Piciformes: mouth cone was suitable for Woodpecker; horny little hook with a long tongue; toe two after the first two; chicks belonging to the late adult birds, climbing birds.
  Common species such as Spotted Woodpecker.
  Passeriformes: Ming Ming bone tubes and developed; toe after three previous, in a plane, suitable nest, the chicks belonging to the late adults, Ming
  Birds. Common species are skylark, swallow, etc..

  Features:
  Take in water through its infancy.
  Have to adapt to the skeletal structure of terrestrial, have four limbs, skin moist, there are many glands.
  Body without scales or hair.
  Forked tongue, inverted, to stretch out.
  Mating and fertilization in water.
  Larvae with gills, the adult is using the skin, mouth breathing and lung lining.
  Classification of Amphibians
  No End
  Example: toad
  Features:
  A skeletal system to adapt to life on land, the body separately, trunk and limbs. Forelimb four toes, hind toe, toes webbed. Hindlimb apply to swimming and jumping are the lung, but the main respiratory organ for the oral lining and skin.

  Body hair coverage, chewing and digestion, can improve energy and nutrient intake;
  Viviparous (platypus, echidna excluded), breast-feeding;
  Temperature. Changes in ambient temperature can be maintained when the body temperature relatively constant, thereby reducing dependence on the external environment, expanding the distribution;
  Cranial expansion of well-developed brain, the intellectual and adaptation to the environment than other animals;
  Strong sensitivity within the limb, there is rapid movement;
  The heart of the left and right two-bedroom completely separated;
  Teeth are divided into incisors, canines and cheek teeth.
  Classification of mammals
  1. Main Features
  (1) body hair, has a fast movement on land capability. Wool is unique to mammals, mammals each year for general
  Hair twice: in spring and autumn molt. Molt is a mammal of the season after coaching change.
  (2) there chewing and digestion. Higher degree of differentiation digestive tract, digestive gland well developed, diverse digestive enzymes. Mammals
  Objects are divided into incisor teeth (incisors), canines (fangs) and molars (teeth), tooth type and number of teeth is the basis for classification of mammals
  One.
  (3) constant temperature, reducing dependence on the environment.
  (4) has a highly developed nervous system and sensory, and coordination ability. Mammalian nervous system mainly in the brain and small
  Brain size increase, cell assembly, cortical thickening. The surface of the fold (ditch and back).
  (5) gives birth, lactation, offspring survival rate.
  The original animal characteristics oviparous, egg shells. (Example: duck Tsui beast)
  After the character is not a real animal placenta, children made in the pouch. (Example: Kangaroo)
  Features real animal placenta, fetal development, improve the output after accounting for the vast majority of mammals. And is divided into 14 categories.
  Insectivorous (example: mole)

  Features:
  Are carnivorous in cats. Large mammals, claws can stretch, good at jumping, canine development, good at ambushes and other animals.
  Example: an elephant
  Features:
  For the largest extant terrestrial animals. Large flat ears, nose and expertise, can help feeding, body hair degradation, foot thick pad of elastic tissue, to supporting body weight. On the front teeth developed, grown in vitro. Food plants Lord.
  Example: Anteater
  Features:
  Forelimb which means two to three specialties, which dug their nests. No one to turn teeth, showed a long tubular snout, long tongue were sticky, could adhere to termites, tail long and hairy. Habitat in the prairie wetlands, good swimming, to termites and ants for food.
  Example: bat
  Features:
  Forelimb specialization, expertise phalanx, phalanges and between the lateral and hind wing students have thin tough membrane, as flight organs. Hind legs with claws, physical habitat can be hung upside down. Breastbone protruding clavicle developed to facilitate flight. Most Hi insectivorous bats, and good insect prey in flight, a few to eat fruit.
  Example: Dolphin

The first tip and a long dorsal fin with ER. Forelimb characteristics into broad paddle-shaped. Non- hind legs, tail length, with horizontal forked caudal fin.
  Cases: Monkey
  Features:
  Thumb relative to other means, suitable for climbing and holding objects. Clavicle developed body with body hair (except palm), refers to a nail, developed brain and sense organs. Eyes forward, with orbital bone. Acts almost human.
  Protozoa
  Features:
  Single cell animals, the body's structure is simple, eat, move and multiply and die. Body is very small, microscopic observation to use animals. Inhabit fresh water, sea water or body fluids of other animals. Such as amoeba .
  Molluscs
  Mollusk diversification shape is very successful biological categories, including all "shell" animals, octopus and cuttlefish. Most of the molluscs living in the sea, some live in brackish water or fresh water border, are also a small department copies are terrestrial.
  Features:
  Soft body, regardless of sect, symmetrical, back, extending down into the cortical mantle, covering most of the body. Mollusk shells in the shell is secreted by the mantle epithelial cells formed.
  Most molluscs have one or two shells, such as snails, clams.
  Others degenerate into the inner shell, hidden under the mantle, such as squid.
  Some types of shell are completely disappeared, such as gills class.
  Worm
  Features:
  Body soft, sub-link, each link has a pair of discharge devices. Such as earthworms and Nereis.
  Soft, round body, parasitic in animals or plants. Such as roundworm and pinworm.
  Arthropod
  Arthropods are the largest one animal, goods moving is also the most numerous, accounting for all the animal species of 85%. On the environment to adapt to an exceptionally strong, local survival, including water, fresh water, mountain, air, soil, Even the animals and plants in vivo and in vitro.
  Main features:
  Symmetrical on both sides of the body, the body section, but some body of fusion into a particular site, such as head and chest. Some arthropods such as spiders, further integration into the head and chest, head and chest. Body appendage, such as foot , antennae, mouthparts and so sub-section.
  Hard body wall, composed mainly of chitin, can provide protection, but also for use as exoskeletons. As hard body wall, impeding the growth of many arthropod molting growth period required.
  Well-developed sensory system, eye with monocular and two compound eyes. Compound eye for visual objects, and monocular as sensitive. In addition, there are touch, taste, smell, hearing and balance organs, better insect and a special sound device .
  Respiratory rather arthropod diversity can surface, gills (aquatic) and trachea (terrestrial) breathing. Spiders are using the book lungs to breathe.
  Classification of arthropods:
  Crustaceans
  Example: shrimp, crab.
  Spiders
  Example: spiders, scorpions.
  Insects
  Example: Butterfly
  More than enough class
  Example: centipede
  Feelings:
  Animal species and in finding pictures, I spent a lot of time and effort, but I think worth it. Because I saw many animals and insects in the book and of these web pages, that is interesting and the knowledge that many animals.
  I know a zoologist is the use of animals with different characteristics and life habits categories. The largest land animals have been extinct Tyrannosaurus, now is the biggest elephant, the smallest is only visible deformation of use microscope insects. I know the original is the childhood growth of amphibians in the water, after growing up living in the land. Some animals that I had to divide them into the same, now that was originally a second-class animals.
  I also noticed that we were to eat is biological, all animals are eating organisms. Most of the animals are useful to us humans, but many animals as we capture and killing, endangered species, especially mammals animals.
  In order to balance the natural ecology, we should not arbitrarily cut down trees, to care for nature. Do not harm animals, because all animals and humans are living beings.

  Origin
  The history of the animal world is animal origin, differentiation and evolution of a long journey. Is from a single cell to multiple cells, never have the spine to spine, from low-moderate to high, from simple to complex. The earliest one-celled protozoa evolved into multicellular invertebrates, sponges emerged door, coelenterate door, flat door animals, animal-shaped door New York, linear animal doors, Annelida, Mollusca, arthropods Phylum Echinodermata. No spine forward by the evolutionary emergence of vertebrates, echinoderms, the earliest vertebrates are cyclostomes, cyclostomes in the process of evolution occurred on the lower jaw, from aquatic to terrestrial. Amphibians were the first land vertebrates board. Although amphibians have been able to board the land, but they are still not completely free from the shackles of the aquatic environment must also breed in the water and spent his childhood. Amphibians continue to evolve from the original, there reptiles. Reptiles can lay their eggs on land, hatch, totally divorced from dependence on the water, a truly terrestrial animals. Reptiles and are cold-blooded animal before the animals, their body will become cold and stiff, this time they had to stop their activities into hibernation.
  Taxon, naming and identification of mold in this way
  Classification system is at the order system, usually including 7 main levels: species, genera, families, orders, classes, door industry. Species (species) is the basic unit, relatives of the species to be classified together, relatives of the are classified together as the Branch, Division scribe the eyes, the head scribe at the Gang, Gang scribe in the door, the door attached to industry. With the progress of the study, classification levels increased, cells can attach the upper and lower secondary units, such as the Master (Chao Gang), subclass, sub-classes, head (over head), sub-orders, sub-project, the total families (superfamily ), subfamily so. There is also the addition of new units, such as shares, group, clan, group, etc. One of the most permanent of the clan, ranging between subfamily and genus. Usually planted classification, based only subspecies of animal cells.

Reference --stuweb.zjhzyg.net/08/_private/0814/081404/_private/new_page_6.htm in our country there are giant panda, golden monkey, Chinese river dolphin, Chinese sturgeon, etc..
  Endangered animals because:
  All natural species and their communities with local environmental conditions where the fit, as long as conditions remain unchanged, can be long-term survival, even in the proliferation or reduced, the process is slow and gradual. Intensification of human activities, but it broke the balance of the same age, leading to species extinction:
  1) Habitat loss, degradation and fragmentation of human energy in the short term to level the hills, so that river, a hundred years the global forest by 50%, this destructive interference in the environment caused by mutations, leading to loss of many species of each other and make a living home - habitat, reduced to extinction, and this situation still continues. In endangered vertebrates, 67% of the species subject to habitat loss, degradation and fragmentation threats.
  The world's 61 tropical countries, half of 49 countries have lost the wild, deforestation, wetlands were drained, grasslands are turning the land, and coral were destroyed ... ... Asia is particularly acute. Bangladesh 94%, 97% of Hong Kong, Sri Lanka 83%, 80% of the wild in India habitat no longer exists. As the saying goes: collapse and disappear, if not a forest, monkeys and many forest-dwelling animals, of course, no "home" can be attributed to "ecology" was originally derived from the Greek word ECO is "home", "home" meaning .
  Extinct species, the migration ability of amphibians and reptiles and the poor nowhere more obvious types of migratory island of Madagascar on 85% of species endemic species, there are more than 60 kinds of lemur class, landing humans 1,500 years ago, after 90% of the forests disappear, the remaining lemur species only 28 species (including the mysterious and body as big as a description of the means monkey). Mainland habitat fragmentation, islands, is the increasingly serious incidents over the past century, which not only limits the spread of animal, feeding, breeding, also increased the threat to survival, when a certain animal from A to B to migration, was found to be eliminated greatly increased the likelihood. At present, China plans to build giant green corridor, is to resolve this conflict.
  2) over-development in endangered vertebrates, 37% of the species is threatened by over-exploitation of many wild animals were being used as "leather wear, wool available, edible meat, organs can be used as medicine," Development and Utilization object Erzao disaster. Like teeth, rhinoceros horns, tiger skins, bear gall, bird feathers, turtle eggs, seal oil, the Tibetan antelope's wool ... ... more and more the meat of wild animals, without exception, a human price to be and sell goods, wanton killing of the planet's largest animals: whales, is to eat whale oil and the production of pet food; Cruel to catch sharks, which have evolved 400 million years of the cartilage of fish fins were cut after the abandonment, just enjoy this Road called shark fin cuisine. Human being in order to meet their marginal interests (fashion, show off, fun, appetites), away away the lives of wild animals. Of wild species of commercial access, often the result is "commercial extinction." At present, the global black market each year the amount of wild animals are more than 10 billion U.S. dollars, with arms, drugs go hand in hand, erode the conscience of mankind, the sins of the world increased. North American passenger pigeon had several 100 million, is seen everywhere, birds, large flying cloud cover blocks out the sun a little more time, the U.S. state of 100 years of colonial development, will be caught doing this action to exterminate the birds. When in September 1914 the last one passenger pigeon died, many Americans were shocked, eyes looked at this has a little more than can be taught the animals actually under development and utilization of human extinction, they erected monuments for the passenger pigeon, the inscription is full of remorse and repentance: "passenger pigeon, a species as a result of human greed and selfishness, extinct."
  4) environmental pollution in 1962, the United States Leiqieerka Morrison's "Silent Spring" caused a global concern about the dangers of pesticides; humans for economic purposes, profit-oriented cast to the nature and behavior of toxic substances are numerous: chemical products, automobile exhaust, industrial waste, toxic metals, crude oil spilled drain, solid waste, detergents, cooling agents, preservatives, water pollution, acid rain, greenhouse effect ... ... and even marine vessels in the military and noise pollution are interference the whale feeding behavior and communication ability.
  Scientists have discovered that highly sensitive to the environmental quality of Amphibians and Reptiles in the scope of the disappearance CP. Increased temperature, UV enhanced, habitat partitioning, chemical Smirnov, has made Chanzao frogs into childhood memories. And various other factors, the impact of pollution on the species are subtle, accumulation, a chronic cause of biological kill "soft knife", the degree of habitat loss against par.
