  1. 1. Brandon Stubbs and Tony Reeves Period 7 5/19/09 Scientific name is Lumbricus terrestis Annelid
  2. 2. Classification <ul><li>One of the subclasses is Hirudinea this subclass is the leaches they have a flattened body and a posterior sucker </li></ul><ul><li>The other subclass is Oligochaeta these are the worms like the night crawlers and earthworms </li></ul>
  3. 3. Body form <ul><li>They are bilaterally symmetrical </li></ul><ul><li>They have a hydrostatic skeleton </li></ul><ul><li>They can be from 1 mm. to 3 m. in length </li></ul>
  4. 4. Reproduction <ul><li>Sexual reproduction allows a species to better adapt to its environment. </li></ul><ul><li>Most polychaete worms have separate males and females and external fertilization. </li></ul><ul><li>Earthworms and other oligochaetes, as well as the leeches, are hermaphroditic and mate periodically throughout the year in favored environmental conditions. </li></ul><ul><li>http://encyclopedia.stateuniversity.com/pages/1499/annelid.html#ixzz0Gc3pG0V9&A </li></ul>
