Title: Kingdom Animalia


1
Kingdom Animalia
2
Characteristics
  • Multicellular
  • Eukaryotic with no cell walls
  • Heterotrophs (consumers)
  • Have a nervous system to respond to their
    environment
  • Locomotion relates to ability to obtain food

3
Protection and Support
  • Though not all animals have a skeleton, those
    that do can be divided into two groups
  • Those with an exoskeleton a hard, waxy coating
    on the outside of the body that protects internal
    organs, provides a framework for support, and a
    place for muscle attachment.
  • Those with an endoskeleton support framework
    within the body that protects some organs and a
    brace for muscles to pull against.

4
In the Animal Kingdom there are 9 Phyla
  • Porifera
  • Cnidaria
  • Platyhelminthes
  • Nematoda
  • Annelida
  • Mollusca
  • Echinoderm
  • Arthropoda
  • Chordate

5
Phylum Porifera
  • Sponges
  • simplest form of animal life
  • live in water
  • Do not move around
  • no symmetry
  • Pores (holes) all over body
  • Examples Tube Sponge, Glass Sponge, Sea Sponge

6
Phylum Cnidaria or Coelenterata
  • Live in water
  • Most have tentacles
  • catch food with stinging cells
  • Examples - Jellyfish, Hydra, sea anemones, and
    corals

7
Phylum Platyhelminthes
  • Flatworms
  • Flat, ribbon-like body
  • Live in water or are parasites
  • bilateral symmetry
  • Examples Planaria
  • eyespots detect light
  • food and waste go in and
    out the same opening

8
Phylum Nematoda
  • Roundworms
  • Round, tubular body
  • small or microscopic
  • bilateral symmetry
  • have both a mouth and anus
  • Live in water or are parasites
  • Examples
  • Hookworm
  • Trichinella

9
Phylum Mollusca
  • Soft bodies
  • Hard Shells
  • Live on land or in water
  • Important food source for humans
  • Phylum Mollusca has three classes

10
Phylum Mollusca
  • Class Gastropoda
  • Or Univalves
  • snails and slugs
  • may have 1 shell
  • stomach-footed - move on stomach

11
Phylum Mollusca
  • Class Bivalves
  • 2 shells hinged together
  • clams, oysters,
  • scallops and mussels

12
Phylum Mollusca
  • Class Cephalopods
  • squids and octopuses
  • internal mantel

13
Phylum Annelida
  • Segemented worms
  • Body divided into segments(sections)
  • Live in water or underground
  • have a nervous and circulatory system
  • eat soil and breakdown organic matter, wastes
    provide nutrients to soil

14
Phylum Echinodermata
  • Hard, spiny skin
  • Live in salt water
  • Radial symmetry
  • name means spiney skinned
  • endoskeleton
  • Examples seastar, sea urchin, sand dollar and
    sea cucumber

15
Phylum Arthropoda
  • Body divided into sections/segments
  • Exoskeleton
  • Jointed legs
  • well developed nervous system
  • largest group of organisms on earth
  • Phylum Arthropoda has 5 classes

16
Phylum Arthropoda
  • Class Arachnida
  • no antennae
  • 4 pairs of legs
  • 2 body regions - cephalothorax abdomen
  • spiders, scorpions, mites ticks

17
Phylum Arthropoda Class Crustacea
  • Shrimp, lobsters, crabs,
  • barnacles, isopods
  • 5 pairs of legs

18
Invertebrate Phylum Arthropoda
  • Class Insecta
  • no antennae
  • 3 pairs of legs
  • grasshoppers, ants, butterflies, bees

19
Phylum Arthropoda
  • Class Diplopoda
  • Millipedes
  • segmented animals
  • Have 2 pairs of legs per segment

20
Phylum Arthropoda
  • Class Chilopods
  • Centipede
  • Segemented animals
  • Have 1 pair of legs per body segment

21
Phylum Chordata
  • 5 classes
  • Fish
  • Mammals
  • Reptiles
  • Amphibians
  • Birds
