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.

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
