ANIMAL KINGDOM Here in the world, there are many different animals. Many animals are basically the same, but some are different. The Animal Kingdom's classification consists of mammals, reptiles, amphibians, brids, fish, insects, and arachids. Mammals are vertebrates that have hair, and females have mammary glands that produce the milk for their young. Reptiles are cold-blooded vertebrates that breathe with lungs and their skin is covered in layers. Most reptiles are amniotic egg layers. The classification of reptiles are alligators and crocidiles, turtles and tortoises, lizards and snakes, and the endagered tuatara of New Zealand. Amphibians are a class of vertebrates that includes toads, frogs, newts, and salamanders. Amphibians spent part of their lives in watr and part on dry land. Amphibians are also cold-blooded animals, which have a variable body temperature that's regulated by their external environment. Fishes are cold-blooded vertebrates that have paired fins, torpedo-like bodies and lay eggs. Many of them breathe by means of gills, but a few breathe atmospheric air through lug-like organs. Insects are animals that are arthropods and have exoskeletons. Insects are the most numerous and prolific group in the animal kingdom. Arachnids are insect-like arthropods with bodies composed of two parts, the abdomen and the cephalothorax, which contains the head and thorax. Most arachnids are carnivorous, but some are parisitic. Some arachnids have a sting that's poisonous to humans.

[] KEEPING THE ENVIRONMENT CLEAN It is highly important that we keep the environment clean. Keeping a clean environment can help us live healthy lives and leave the future generations a healthy Earth. We should raise awareness about the importance of a clean environment and to make the environment healthier. We need to achieve a clean environment so we must work together to take care of our planet. There are many ways to create a clean environment. Ways to keep a clean environment: Simplify life whenever whenever possible. The simpler your life the more you contribute to a clean environment. The less waste we create the better off the environment. Use less products that come from trees in your home and at work. Try to have less trash at home because that can prevent landfills from overflowing for future generations. This can be done by purchasing products with as little packaging as possible and recycling as much of your waste as possible.

It is easy to take steps to create a clean environment and we all should be focused on creating a clean environment. []

MOLLUSKS Mollusks are invertebrates that have soft bodies that consist of three basic parts, a foot, a visceral mass, and a mantle. The phylum Mollusca is the largest and most diverse phylum of animals next to arthropods. Mollusks can be found in almost every ecosystem on earth. Today, there are 100,000 species of mollusks identified. The body of mollusks is composed of the shell and the fleshy, living part. The fleshy parts of a mollusk can be divided into the foot and the visceral mass. Classifications of Mollusks: Gastropada Bivalvia Cephalopada Polyplacophora

ARTHROPODS Arthropods are animals with segmented bodies and six or more jointed legs. Arthropods are the largest animal group on Earth. They are found everywhere- on land, in trees, in freshwater and saltwater, and even underground. Arthropods are generally large but some are quite large. Some of the most familiar arthropods are butterflies, beetles, flies, ants, bees, spiders, scorpions, shrimp and crabs. All Athropods have: 1. A hard outer body covering called an exoskelton. 2. Specialized mouth parts. 3. Jointed legs 4. Compound eyes 5. Segmented body

ECHINODERMS Echinoderms are radially symmetrical animals that are only found in the sea. There are no echinoderms on land or in fresh water. Many, but not all, echinoderms have spiny skin. There are over 6,000 species. Radial symmetry means that the body is a hub, and tentacles are spokes coming out of it. As larvae, echinoderms are bilitarally symmetrical but as they mature the become radially symmetrical. Echinoderms have tube feet with suction pads situated at their extremities. The tube feet are hydraulically controlled by a vascular system. The system supplies water through canals of small muscular tubes to the tube feet.

A few characteristics of Echinoderms: All Marine Known as spink-skinned animals. Includes sea stars, brittle stars, sand dollars, sea urchins, and sea cucumbers.

5 classes of Echinoderms: 1. Crinoidea 2. Asteriodea 3. Ophiciroidea 4. Echinoidea 5. Holothuroidea

AVES Aves are birds that are a diverse group of vertebrates that evolved from reptiles. 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 water as skilled swimmers.

Characteristics that are unique to birds: Feathers- Provide insulation and enable flight. Bills- Pair of toothless mandibles covered with a horny sheath of keratin. Furcula- A bone located in the bird's chest that prevents compression of the chest cavity during the downstroke of a wingbeat.

Birds also exhibit these characteristics: Fused bones in pelvis, feet, hands, and head. Produce large, richly provisioned external eggs. Extraordinary communication and song production.
