PPT-Phylum Annelida

1 Phylum Annelida Class Polychaeta Class Clitellata Phylum Annelida 2 Annelid Characteristics Defining Characteristics One or more pairs of chitinous setae The phylum includes polychaetes earthworms leeches and vestimentiferans. Today we will study the annelids, the segmented worms, and the arthropods, a huge group that contains insects, spiders, and crustaceans. Three tissue layers are present in both of these groups. Also Annelid Characteristics. Annelids are to be found in marine, freshwater, and terrestrial habitats. The body is vermiform, bilaterally symmetrical, and segmented (. metamerism. ). Each segment is separated from contiguous ones by a transverse septum. 5 - . 1. Coral, Anemones, Sea Fans, and Jellyfish. Chapter 5 Pages 5-33 & 5-34. Characteristics of Phylum Cnidaria. 5 - . 2.
