| Mammal | Give birth to live young, have hair or fur, have mammary glands, are warm-blooded. |
| Fish | lay eggs, have scales and fins, are cold-blooded, and use gills to breath under water. |
| Amphibians | live on land and in water, are cold-blooded, lay eggs, have moist skin and webbed feet. |
| Reptile | have scales, dry skin, usually lay eggs, are cold-blooded |
| What are the 8 classes of invertebrates? | porifera, cnidaria, platyhelminthes, nematoda, annelida, arthropoda, mollusca, echinodermata |
| Porifera | have pores and tissues but no organs, and live in water - example: sea sponge |
| Cnidaria | do not have neads or teails, have soft bodies and poisonous tentacles, live in the water - example: sea anamones and jelly fish |
| Annelida | have eyes, gills, a jaw, and circulartory, digestive and nervous system. Are Segmented. example: earthworm |
| Arthropoda | tough outer skeleton (exoskeleton), jointed legs, and a body made up of two or more sections - example: lobster, spiders, insects |
| Mollusca | Most have a shell, gills, and a jaw. They have internal organs and a circulatory system. Some have well-developed brains. example: snails, octopuses |
