Arthropoda Crustacea

  1. 1. Phylum: Anthropoda Subphylum: Crustacea Sarah H & Destini T 5/19/09 2 nd period Deep sea lobster Scientific name: Puuerulus spp.
  2. 2. Classification <ul><ul><li>Can be divided into these groups: </li></ul></ul><ul><ul><li>Class: Insecta(insects) </li></ul></ul><ul><ul><li>Class: Collembola (springtails) </li></ul></ul><ul><ul><li>Class: Protura (proturans) </li></ul></ul><ul><ul><li>Class: Diplura (diplurans) </li></ul></ul><ul><ul><li>Class: Myriiapoda (myriapods) </li></ul></ul><ul><ul><li>Class: Crustacea (crustaceans) </li></ul></ul><ul><ul><li>Class: Arachnida (arachnids) </li></ul></ul><ul><ul><li>Class: Pycnogonida (sea spiders) </li></ul></ul><ul><ul><li>Class: Merostomata (horshoe crabs) </li></ul></ul>
  3. 3. Description <ul><li>Variety of forms </li></ul><ul><li>Basic crustacea body has a number of segments </li></ul><ul><li>Called somites </li></ul><ul><li>Linked by flexible areas that allow some movement </li></ul><ul><li>bilaterally symmetrical </li></ul><ul><li>Exoskeleton </li></ul><ul><li>Crustaceans have two pairs of antennae and two pair of maxillae </li></ul>
  4. 4. Reproduction <ul><li>Sexual reproduction </li></ul><ul><li>Sexes are separate fertilization is external in aquatic forms, internal among the terrestrial forms </li></ul><ul><li>Some pathogenic </li></ul>
  5. 5. Digestive system <ul><li>digestive glands increase the surface area for digestion </li></ul><ul><li>Divided into 3 main regions: foregut, midgut, and hindgut </li></ul><ul><li>Hindgut is involved with water absorption </li></ul>
  6. 6. Circulatory system <ul><li>Open circulatory system </li></ul><ul><li>Heart pumps blood over the brain </li></ul><ul><li>Holes in the side of the heart let blood in to go around again </li></ul>
  7. 7. Respiratory <ul><li>Respiratory structures allow the arthropods to metabolize more easily and move quickly </li></ul><ul><li>High metabolism rates need fast oxygen delivery, and arthropods can achieve this with respiratory organs that have a large surface area for collecting oxygen quickly </li></ul>
  8. 8. Habitat <ul><li>Live mainly in fresh water and salt water </li></ul>
  9. 9. Interactions with humans <ul><li>Used as Halloween costume </li></ul><ul><li>Used for food (lobster, shrimp, and crab) </li></ul><ul><li>People make a living out of catching them and selling to markets and restaurants </li></ul>
  10. 10. Unique features <ul><li>Exoskeleton </li></ul><ul><li>Found in abundance within the ocean, similar to the abundance of insects on land </li></ul><ul><li>Includes the spider crab: largest one ever had a leg span of 12 feet and weighed 41 pounds </li></ul>
