Annelids/Segmented worms Example: Earth worms

*Definition: An animal, such as the earth worm, whose body is made up of connected sections, or segments.*Body Systems: Circulatory system, five enlarged tubes act as hearts, nerve center, or brain, major vessels that pump there blood. *Reproduction: sex organs, after worms mate, both partners lay eggs and produce slimy covering that forms a cocoon that protects the eggs. *Food: Two sets of muscles enable the worm to move through soil, where it takes in its food through its mouth. *Habitat: they live in most soil or usually under ground. *Predators & Problems: moles and birds eat earth worms.*Adaptations & Fun Facts: They breath through there thin moist skin.

ArthropodsExample: Scorpions

*Definition: An animal that has a jointed exoskeleton.*Body Systems: Digestive system, Circulatory system, two openings, and a brain.*Reproduction: Sexual reproduction, female lays fertilized eggs.*Food: Most Arthropods eat other animals.*Habitat: some arthropods live in water.*Predators & Problems: we (humans) eat arthropods such as, sea food like, lobster. *Adaptations & Fun Facts: There exoskeleton does not get bigger as the animal grows.

Porifera/SpongesEx: Venus-flower basket sponge

*Definition: A type of animal that filters the water it lives in to get food. *Body Systems: Round or finger like. Has an inner and an outer layer of cells, the skeleton is made up of tough protein called spicules. *Reproduction: most often they reproduce asexually, buds break of and grow new sponges, some sponges reproduce sexually , forming the cells , an egg forms a larva that leaves and attaches to the sea bottom. *Food: they eat small food particles, they filter the water around them to get food. A jelly like layer caries food to other cells. *Habitat: They live at the bottom of the ocean in shadowy areas. (lakes, ponds, streams growing on heard surfaces.*Predators & Problems: divers pull them out of the water and let them dry.*Adaptations & Fun Facts: They can blend into the sea bottom and don’t look like animals. Many people didn’t know they were animals and there food comes from the water.

Nematodes/Round wormsExample: Hook Worms

*Definition: An animal with a round tube like body, that has a digestive system with 2 openings. *Body Systems: Has a nerves system with a brain, and other simple sense organs. *Reproduction: Nematodes reproduce sexually… it has sex organs that enable it to reproduce sexually.*Food: It feeds on other animals or organisms. They have one whole in the front for eating and one in the back for leaving waist. *Habitat: They live in soil or dirt, and some live in other animals. *Predators & Problems: fungus, other nematodes, and anything bigger than it Eats it or is its predators.*Adaptations & Fun Facts: living in animals help them survive and get food.
