    3. 3. Whales closest relatives are cows <ul><li>Whales are thought to have evolved from a group of land animals that are classified as even toed ungulates which are commonly known as cows </li></ul><ul><li>In order for the whales to be able to live in the ocean rather than on land they had to evolve and adapt to that environment </li></ul>
    4. 4. Adaptations that whales have to survive in the ocean <ul><li>Be able to swim </li></ul><ul><li>Be able to live in cold water </li></ul><ul><li>Be able to hold their breath </li></ul><ul><li>Obtain food from the ocean (there is no grass in the ocean) </li></ul>
    5. 5. Swimming Adaptations <ul><li>Fusiform or football shape </li></ul><ul><ul><li>The most efficient shape for moving through water </li></ul></ul><ul><li>Tail flukes for swimming </li></ul><ul><li>Pectoral fins for steering </li></ul><ul><li>Dorsal fin that helps them stay upright </li></ul>
    6. 6. Blubber an adaptation to live in cold water <ul><li>Blubber is fat </li></ul><ul><li>Fat is insulation </li></ul><ul><li>Fat is also a food source </li></ul>

    8. 8. Toothed whales and Baleen whales <ul><li>Toothed whales eat fish or squid and use echo location to locate prey </li></ul><ul><ul><li>A group of toothed whales working together to catch prey is called a pod </li></ul></ul><ul><li>Baleen whales have rows of hairy plates which strain out plankton from huge mouth fulls of water </li></ul>
    9. 9. Adaptations that whales needed to move from life on land to life in the ocean <ul><li>How did they adapt from walking on land to swimming in the ocean </li></ul><ul><li>How do they keep warm </li></ul><ul><li>What happened to their nose </li></ul><ul><li>How did they adapt from eating plants to eating plankton or fish </li></ul>
