Kingdom Animalia

1
Kingdom Animalia
2
General Characteristics

• Multicellular (made of more than 1 cell)
• Eukaryotic (have a nucleus)
• Heterotrophs (cannot make their own food) that
  ingest their food
• Lack cell walls

3

• Cells are organized into tissues that make up
  organs
• Most reproduce sexually (DNA contributed from 2
  parents)
• Most are motile (can move)

4
Animals are described according to their
arrangement of body part or symmetry.
5
Animal Kingdom Phyla

• INVERTEBRATES - do not have a backbone

6
Phylum Porifera

• Aquatic (live in the water)
• Lack true tissues organs
• Sessile (cant move) adults
• Filter feeders (strain tiny floating organisms
  from the water)

7
Examples of Porifera
Bath Sponge (loofah)
8
Phylum Cnidaria

• Aquatic
• Radial symmetry (body plan in which body parts
  repeat around the center of the body)
• Tentacles bear stinging nematocysts
• Some members are sessile

9
Examples Cnidarians
Portuguese man-of-war
Moon Jellyfish
Sea Anemone
Coral Reef
10
Phylum Platyhelminthes

• Flatworms
• Bilateral symmetry (body plan in which only a
  single, imaginary line can divide the body into
  two equal halves)
• Some free-living and some parasitic (live in and
  take in nutrients from another organism)

11
Examples Flatworms
Planarian (free-living)
Liver Fluke (parasites)

• Tapeworm (parasites)
• comes from undercooked meats

12
Phylum Nematoda

• Roundworms
• Digestive system has two openings a mouth and
  an anus (this is the first group of Animals that
  has this trait)

13
Examples Roundworms
14
Heartworm
15
Phylum Annelida

• Segmented worms
• Digestive system has 2 openings
• Closed circulatory system (blood is contained
  within a network of blood vessels)

16
Examples Segmented Worms
Fanworm (live in salt water)
Earthworm (terrestrial- live on land)
Leech (most live in fresh water)
17
Phylum Mollusca

• Soft-bodied often with a hard shell
• Digestive system with 2 openings
• Muscular foot can be used for crawling,
  burrowing or as tentacles to capture prey

18
Examples Mollusks
19
Phylum Arthropoda

• Exoskeletons (external skeleton)
• Jointed appendages (structures such as legs and
  antennae that extend from the body wall)
• Open circulatory system (blood is not always
  contained within a network of blood vessels)
• Largest animal phylum

20
Examples Arthropods
Tick
Scorpion
Trilobite
Spider
Crayfish
Crab
Barnacles
Grasshopper
Ant
Centipede
Millipede
21
Phylum Echinodermata

• Live in salt water
• Spiny Skin
• Radial symmetry in adults
• Endoskeleton (internal skeleton)

22
Examples Echinoderms
23
Phylum Chordata

• Dorsal (runs along the back), hollow nerve cord
• Tail during at least part of development

24
Subphylum Urochordata

• live in salt water examples sea squirts
  (tunicates)

Sea Squirts (Tunicates)
25
Subphylum Cephalochordata

• fishlike live in salt water examples

26
Subphylum Vertebrata

• most possess a backbone endoskeleton head with
  a skull brain

27

  around mouth slimy example hagfishes

28

• Class Cephalaspidormorphi live in fresh salt
  water no jaws circular mouth lined with
  toothlike structures example lampreys

29

• Class Chondrichthyes have jaws, fins
  endoskeleton of cartilage most live in salt
  water Examples sharks rays
