Naturally-resistant biotypes may also 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 EMILIE ARBOUR. MICHAELA PEACE. ALLIE PENROSE. JENNIFER YOUNG. INTRODUCTION. Kingdom: Animalia. Phylum: Arthropoda. Subphylum: Mandibulata. Class: Hexapoda or Insecta. 90. % . of arthropods are insects. More species (200,000 ) than any other animal phylum except Arthropoda. Soft body – often protected by CaCO. 3. shell. Unsegmented, typically bilaterally symmetrical. I. Phylum Mollusca. ©2004 Amanda Demopoulos. Arthropods. Enormously diverse phylum. Many parasitic arthropods serve as hosts for a number of parasites (hyperparasitism) from cestodes to viruses. We focus on the crustaceans, insects, and arachnida. Aschelminthes : Roundworms Not the Phylum name 7 Phyla in this grouping Characteristics Most are freshwater Cylindrical Unsegmented Bilaterally symmetrical Triploblastic ( pseudocoelomates ) Dioecious Animal Classification Living organisms are classified into five kingdoms. Each kingdom is further split into smaller groups called Phyla (singular phylum) In each Phyla there are classes and then classes are subdivided into orders. Slide 1. The phylum Arthropoda.
