All animals are members of Kingdom Animalia, also called Metazoa. This kingdom does not include prokaroytes. All members of the Animalia are multicellular, and all are heterotrophs (that is, they rely directly or indirectly on other organisms for their nourishment). Most ingest food and digest it in an internal cavityhe 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.They all mailnly reproduce sexually, by means of differentiated eggs and sperm, but their are some animals that reproduce asexually (Myers).

There are many ways humans can make the enviroment a safe place to live. One way easy way is to recycle household items. The city has recylcing faclities all over the area, some for aluminum cans, plastic containers, card board, and etc... We can all make our environment a better place to live as long as we all try to contribute, this can help reduce our land fields. Another way we can help our environment is to reuse common household items. For example, you can always reuse aluminium pans like for pies or cakes, galssware instead of paper products, and many more. If you no longer want your furniture, clothes, or applicances, be a kind hearted person and give them away to a charity and to the less fortunate (Recycle).

The phylum Mollusca is the largest and most diverse phylum of animals next to arthropods. Mollusks can be found in nearly every ecosystem on earth, from high, barren mountains to grassy plains, lakes, rivers and in all seas and oceans. Their are two structures of the Mollusk, the mantle and the radula. To which they are only found in Mollusca and nowhere else in the animal kingdom. Most taxonomists now recognize eight classes of mollusks, based mainly on differences in the foot and shell. These differences are usually quite apparent, making it easy to identify on sight the class to which a mollusk belong to. Some animals that belong in this category is snails, slugs, clams, and many more.

Anthropods are animals with segmented bodies and six or more jointed legs. They are the largest group of animals on Earth. They are found everywhere on land, in trees, in freshwater and saltwater, and even underground. Arthropods are generally small. MostMost of them are less than 1cm long. Some of the most familiar arthropods are butterflies, beetles, flies, ants, bees, spiders, scorpions, shrimp, and crabs. Most anthropods belong to one of three major groups: insects, crustaceans, or arachnids.

Echinoderms are radially symmetrical animals found only in the sea. Echinoderms means spiny skin, however not all the echinoderms have spiny skin. There are more than 6,000 species. They usually have five appendages. Given enough time, sea stars can grow back their arms that have been damaged or removed. For a few species, the injuried arm can grow back into a complete sea star. There are two sub-types of sea stars which is asteroideas, that are true sea and sun stars. Asteroideas have arms connected to each other. The second type of sea star is the ophiuroideas that are brittle and basket stars, which have arms but do not connect with each other. > []

Today, an estimated 300 billion birds belonging to more than 9000 species inhabit virtually every terrestrial habitat on the planet. There are even many species of birds that are at home in the water as skilled swimmers and divers. Birds is one of the most disistinguishable group of vertebrates, they are known for feathers, bills, furcula, and many more.

All dolphins are toothed whales belonging to the sub-order, odontocetes, of the order cetacea humpback whales. As a group, dolphins are often referred to as "small" cetaceans, even though some of them are quite large, attaining lengths of over 20 feet. In addition, although the terms dolphins and porpoises are often used interchangeably, they really refer to two different types of animals.Porpoises belong to the family Phocenidae. Dolphins belong to the family Delphinidae. Dolphins possess a distinct beak. Most species of dolphins are larger than porpoises, with the males usually being larger than the females. The family Delphinidae is the largest and most diverse family of the cetacean order and includes 26 living species. Several species of dolphins are found in Hawaiian waters.
