= FINAL FOR ZOOLOGY = All animals are members of the Kingdom Animalia, also called Metazoa. Prokaryotes and protists are not members of this kingdom. All members of this kingdom are multicellular, which are all also heterotrophs. Animal cells lack the rigid cell walls that characterize plant cells. The bodies of most animals are made up of cells organized into tissues, each tissue specialized to some degree to perform specific functions. Most animals are capable of complex and relatively rapid movement compared to plants and other organisms. Most reproduce sexually, by means of different differentiated eggs and sperm. Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material. We have about 9 or 10 million species of animals inhabiting the earth.

 The environment can be safer by "going green". It can help the economy tremendously and also help our health. The environment can be saved by protesting in nature's bad habit of destroying our land and trees. Many people have tied themselves to trees just to help save our environment from being destroyed. Also, saving the environment can conclude recycling, cleaning, and living healthy.

Mollusks is the largest and most diverse phylum of animals next to arthropods. Mollusks can be found anywhere and everywhere including mountains, lakes, rivers, oceans, etc. Mollusks are composed of the shell and the fleshy, living part. The foot is a distinctive molluscan feature and the visceral mass includes the organs for digestion, circulation, reproduction, and respiration

 Arthropods are the largest animal group in the Kingdom. In fact, they are the largest animal group on Earth. They have segmented bodies and six or more jointed legs. Arthropods can be found on land, in trees, in freshwater and saltwater, and even underground. They are generally small, about less that 1 cm long, but some are large. For example, the king crab is a large arthropod. Small arthropods include butterflies, beetles, flies, ants, bees, spiders, scorpions, shrimp, and crabs. 

Echinoderms are characterized by radial symmetry, several arms radiating from a central body. Consisting of five equal segments in the body, each contains a duplicate set of various internal organs. They have no heart, brain, nor eyes. Their mouth is on the underside and their anus is on top. They have tentacle-like structures called tube feet. They are hydraulically controlled by a remarkable vascular system. This system supplies water through canals of small muscular tubes to the tube feet. As the tube f eet press against a moving object, water is withdrawn from them, resulting in a suction effect. When water returns to the canals, suction is released. The resulting locomotion is generally very slow. 

Aves are in the vertebrate class which include birds, who are an extremely distinctive and successful clade. They were descended by the dinosaurs, but yet have still evolved into remarkable specializations for flight: a unique "one-way" breathing system, light yet strong hollow bones, a skeleton in which many bones are fused or lost, powerful flight muscles, and most importantly: Feathers. 

There are many reptiles all over the world. There are iguana's, snakes, frogs, turtles, so many of them to even name. The can either have no legs and slither like a snake, have 4 legs to jump or crawl like or frog or alligator, and some even have 2 legs to walk. If you havent noticed, we see reptiles everywhere we go. They live by the water, in water, on land, and everywhere on the planet. http://animaldiversity.ummz.umich.edu/site/accounts/information/Animalia.html http://www.globio.org/glossopedia/article.aspx?art_id=15 http://www.oceaninn.com/the-nature-preserve/mollusks/ http://www.starfish.ch/reef/echinoderms.html http://www.ucmp.berkeley.edu/diapsids/birds/birdintro.html http://www.reptilechannel.com/
