  1. LABORATORIOAnnelida EJERCICIO 12

  2. Goals for today • Learn to recognized the PhylumAnnelida from other animals • Learn the main ‘diagnostic’ characteristics • Learn about some species biology

  3. Annelida Annelids include earthworms, leeches, and marine polychaetes. Lophotrochozoa Key characteristics of the phylum: • coelomates • Triploblastic • Bilateral symmetry • Cephalization • Protostomates • Segmentation or metamerism • Belong to phylogenetic clade: Lophotrochozoa • Complete digestive system Rotifera Porifera Annelida Mollusca Ecdysozoa Lophophorata Deuterostomia Platyhelminthes Cnidaria and Ctenophora Lophotrochozoa Protostomia Radiata Bilateria Parazoa Eumetazoa

  4. Annelida: Your Tasks Exercise 12A: • Phylum: Annelida • ClasePolychaeta • Genus:Nereis Nereisis a sandworm strictly marine. They live in the mud and debris of shallow coastal waters often in burrows. Largely nocturnal. They reach 0.5 m

  5. Annelida: Polychaetes 1. Observe lamina de parapodia. Identify the parts in the figure. Where is the notopodium and neuropodium?

  6. Annelida: Polychaetes 1. Observe preserved polychaetes. Put one in a petri dish and observed the following structures in the dissecting scope

  7. Annelida: Your Tasks Exercise 12B: • Phylum: Annelida • ClaseOligochaeta • Genus:Lumbricusterrestris Lumbricusterrestrisprefers moist, rich soil that is not too dry or sandy. They are primarily nocturnal and come out of their borrow at night to forage

  8. Annelida: Lumbricus 1. Observe slide of cross section of an earthworm: look for the following parts

  9. Annelida: Lumbricus 1. Dissection: of an earthworm and look at the external anatomy

  10. Annelida: Lumbricus 1. Dissection: of an earthworm and look at the internal anatomy What are the crop and gizzard for? Is their circulatory system open or close?

  11. Annelida: Lumbricus Dissection in a ‘fresh’ worm, noticed the location of the typhlosole Wha is the function of the typhlosole?

  12. Disección: Lombriz de Tierra Septos Intestino Buche Molleja Vesículas seminales Faringe Receptáculos seminales Boca

  13. Annelida: Your Tasks Exercise 12C: • Phylum: Annelida • ClaseHirundina • Genus:Hirudomedicinalis Medicinal leeches are any of several species of leeches, but most commonly Hirudomedicinalis, the European medicinal leech

  14. Annelida: Hirudo Medicinal leeches are now making a comeback in microsurgery. They provide an effective means to reduce blood coagulation, to relieve venous pressure from pooling blood (venous insufficiency), and in reconstructive surgery to stimulate circulation in reattachment operations for organs with critical blood flow, such as eyelids, fingers, and ears.The therapeutic effect is not from the blood taken in the meal, but from the continued and steady bleeding from the wound left after the leech has detached. http://www.arkive.org/medicinal-leech/hirudo-medicinalis/video-00.html Video

  15. Annelida: Hirudo 1. Observe slide of a leech: identify the oral and caudal suckers, pharynx, and crop.
