Chapter 30 1 The Chordatespwp[1]

  1. 1. Tedra McNair April 2, 2009 Period, 2
  2. 2. What Is A Chordate? <ul><li>Chordates (KAWR-dayts) are members of the phylum Chordata. </li></ul><ul><li>To be considered a chordate an animal must have three key characteristics </li></ul><ul><ul><ul><li>A Dorsal Hollow Nerve Chord </li></ul></ul></ul><ul><ul><ul><li>Pharyngeal (fuh-RIN-jee-ul) pouches </li></ul></ul></ul><ul><ul><ul><li>A Tail That Extends Beyond The Anus </li></ul></ul></ul>
  3. 3. Pharyngeal Pouches (P. Pouches) <ul><li>Shark Pharyngeal </li></ul><ul><li>Are structures that are paired in the throat (or pharynx) region. In some chordates like fishes and amphibians they develop slits that connect the P. Pouches to the outside of the body. </li></ul>
  4. 4. What Is A Fish? <ul><li>Anatomy of a Fish </li></ul><ul><li>Fishes are aquatic vertebrates </li></ul><ul><li>Most fish have paired fins, scales, and gills. </li></ul><ul><li>Fins are used for movement. </li></ul><ul><li>Scales are used for protection. </li></ul><ul><li>Gills are used for exchanging gases. </li></ul>
  5. 5. The First Fishes <ul><li>Ancient Jawless Fish </li></ul><ul><li>The Earliest fish to appear in record were odd looking. They were also jawless with armored body plates. They lived in the oceans in Cambrian Period, about 510 million years ago. </li></ul>
  6. 6. Evolution of Fish <ul><li>Fishes were the first vertebrates to evolve. The evolution of jaws and paired fins were a key development during the upcoming of fishes. </li></ul>The First Fishes
  7. 7. Function of Fish <ul><li>Feeding </li></ul><ul><li>Fishes are seen in every mode of feeding. Such as herbivores, carnivores, parasites, filter feeders, and detritus feeders. Some carp, eat algae, aquatic plants, worms, mollusks, arthropods, dead fish, and detritus. Fish such as the Barracuda, are highly specialized carnivores. </li></ul><ul><li>The fish above are Deep-Sea Anglerfish, it uses a fleshy bait a.k.a. built in “fishing pole” to prey on other fish. A perfect example of a carnivore. </li></ul>
