=**Animal Kingdom & Environment Safety** =
 * In animal kingdom there are different types of animals, but at the same time they all are not similar . There are several animals that does not have backbones , and they are Protozoa , Echinoderms , Annelids , Mollusks , Arthropods , Crustaceans ,Arachnids , Insects . And they are called Invertebrates . And the animal's that does have backbones are Fishes , , Reptiles , Birds , Mammals , Marsupials , Primates , Rodents , Cetaceans , and Animals such as seals . And they are called Vertebrates . Finally its time for the safety we can have safety by recycling like papers , plastic , glass , etc. safety is like a big part of the world because it's a lot of things that be going on . And one of the main ones is cars and all the fuse getting in the air , and if we were to ride bikes or even walk it would make a big difference.**

 **Invertebrates**

Vertebrates

__//**Mollusks**//__ These animals are similar there are about 50,000 of them, they all are very rare , and the only time you would find them is if you go deep down in the ocean or sea. And they have three body regions and they are the head that contain the "BRAIN" and the sense organs. Second the "VISCERAL MASS" and that contains the internal organs, and last but not least the "FOOT" is the muscular part of the body.

__//**Arthropods**//__ They have conquered land, sea and air, and make up over three-fourths of all currently known living and fossil organisms, or over one million species in all. Since many arthropod species remain undocumented or undiscovered, especially in tropical rain forests, the true number of living arthropod species is probably in the tens of millions

Echinonderms They contain 6000 species gets its name from the Greek, literally meaning "spiny skin" . sea stars, urchins, brittle stars, and sea cucumbers. They are simple animals, lacking a brain and complex sensing organs. Echinoderms are characterized by their radial symmetry, water vascular system and internal skeleton.  The most striking feature of all echinoderms is their pentamerous radial symmetry. That is, the body can be divided into five parts (or appendages) which point outward from the center of the body. Interestingly, although most mature echinoderms are radially symmetrical, the larvae usually have bilateral symmetry. During the process of maturing, the echinoderm will change its body shape and settle down on the sea floor. http://www.oceaninn.com/the-nature-preserve/echinoderms/

Aves heir skeleton is completely bony and aerodynamically suitable for flying. Long bones are tubular and therefore extremely light. The skull is fixed to the backbone only with one vertebra just like in the Reptilia Class. A beak is created by prolonging the upper and the lower jaw. A neck is quite long and very movable. A chest bone is wide with a number of muscles, especially those responsible for flying, are fixed to it. Even the bone in the wings is attached to the chest bone. The birds’ body is covered with feathers. It is extremely light and on the other hand it is also a thermal isolation. Feather lies in two layers. **Physiology:** The birds breathe with lungs however these cannot be extended. The lung capacity is extended by five pairs of air sacks which store the air. These sacks are located next to some inner organs and tubular bones. Some birds have got even a vocal organ. The heart is divided into two atriums and two ventricles. Deoxygenated blood flows through the right heart whereas the oxygenated blood flows through the left heart. So there are two separated blood circulations. The blood circulation starts in the right atrium and then the blood flows into the right ventricle. From the right ventricle the blood flows into the lungs where it is oxygenated. Subsequently it flows into the left atrium and then into the left ventricle. From the left ventricle the oxygenated blood flows into the entire body to all organs. There it gives inevitable oxygen to tissues and last but not least the deoxygenated blood comes through veins into the right atrium. In the right atrium it starts all over again. Birds belong to endothermic animals, so their body temperature is stable and is not influenced by the environment. The average body temperature is about 42 Celsius degrees. In the brain we can observe a huge development especially in the frontal part. Birds use their instinct very much, besides they take care of their offspring. Their orientation skills are remarkable too. http://www.wildanimalsonline.com/birds/  __//** mammals **//__ There are about 5,000 species of living mammals. They are divided into three subclasses and about 26 orders (there is no consensus among biologists). Unlike other animals, mammals have body hair, have 3 middle ear bones (the malleus, incus, and stapes), and nourish their young with milk that females produce in modified sweat glands that are called mammary glands. http://www.enchantedlearning.com/subjects/mammals/Groups.shtml Mammals are friendly or fierce, cuddly, cute and/or awesome depending on which ones you look at. They fascinate and horrify us. We eat them, ride them, keep them as pets, makes clothes out of them, hunt other mammals with them and use them as substitutes for ourselves in scientific, particularly medical, research. We use them to carry our burdens, support our foolish habits (gambling) and expect them to entertain us. To most people animals are mammals.Most people are totally dependent on non-human mammals to keep their lives functioning (Vegetarians and Vegans excepted) and many of us need them as emotional supports as well. We are mammals (genetically a man and his __<span style="background-color: transparent; border-bottom-color: #006400; border-bottom-style: solid; border-bottom-width: 0.075em; border-color: initial; border-left-style: none; border-right-style: none; border-top-style: none; border-width: initial; bottom: auto; color: #006400; display: inline !important; float: none; font-family: inherit; font-size: 16px; font-variant: normal; font-weight: normal; left: auto; line-height: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 1px; padding-left: 0px; padding-right: 0px; padding-top: 0px; position: static !important; right: auto; text-align: left; top: auto; white-space: normal;">[|dog] __ are 97% the same) and we love them because they are like us. We use them to describe people (someone is a dog, bitch, stallion, pig, cow, kitten, bunny; we run like a rabbit, weasel out of a deal or are as sly as a fox, strong as an Ox, and can have a whale of a time, etc). Our mammalian cousins are very important to us. http://www.earthlife.net/mammals/welcome.html
