3. Kingdom Animalia

4. Body Symmetry of Animals
Information to know
Body Symmetry of Animals

5. Bilateral Symmetry: a single plane divides body into two mirror images

6. Radial Symmetry: can be cut in half along many planes that allow for nearly identical halves

7. Asymmetry cannot be divided into mirror images

8. Kingdom Animalia

9. Basic Characteristics
Multicellular
Eukaryotic
Heterotrophic
Mostly motile (few exceptions)
Primarily sexual reproduction but some asexual.

10. Comparative Anatomy

11. Nutrition Organisms in the kingdom Animalia are heterotrophs.
Some organisms are herbivores, carnivores and omnivores.

12. Asexual Reproduction in Animals
Budding – a new organism in formed from a bud of the parent
For example, hydra:
Regeneration – a new organism develops from fragments of parent
For example, planaria

13. Sexual Reproduction in Animals
Involves the production of a sperm (spermazoa) and an egg (ova) [haploid sex cells] which will fuse during fertilization to create offspring.

14. Fertilization Aquatic Animals
External fertilization where sperm and egg fuse outside the body
Sharks are an exception
Terrestrial Animals
Internal fertilization where the sperm and egg fuse inside the body
Development of offspring can be internal or external

15. Shark Reproduction

16. Characteristics Used To Classify Animals into Phyla
Multicellular
Heterotrophic
Ingest food
Central digestion cavity
Sexual reproduction
Germ layers
Type of digestive tract
Body symmetry
Coelum

17. Classification of Animals
Scientists have divided the Animal Kingdom into two main groups:
Vertebrates (animals with a backbone)
And
Invertebrates (animals without a backbone)

18. Animals with backbones can be divided into five more groups:
Vertebrates
Animals with backbones can be divided into five more groups:
Mammals
Reptiles
Birds
Amphibians
Fish

20. Animals without a backbone.
Invertebrates
Animals without a backbone.

22. The 9 Phyla of Kingdom Animalia
1. Phylum Porifera
2. Phylum Cnidaria
3. Phylum Platyhelminthes
4. Phylum Nematoda
pinworm

23. The 9 Phyla of Kingdom Animalia
5. Phylum Annelida
6. Phylum Mollusca
7. Phylum Echinodermata
8. Phylum Arthropoda

24. The 9 Phyla of Kingdom Animalia
9. Phylum Chordata

25. Insects & Arthropods

26. Phylum Arthropoda Habitat: terrestrial, aquatic, air
Symmetry: bilateral
Body cavity: coelmate
Reproduction: sexual
Motile
Organization: body systems
Digestion: extracellular
Fertilization: internal

27. Phylum Arthropoda

28. Arthropoda: Success and Diversity
Exoskeleton: protection
Body Segments
Nervous System: larger brains
Nutrition process: can obtain food in many ways

29. Insects: highly adaptive traits
Many feeding methods
Small: hiding, small spaces
Movement: quickly (3 pairs of legs)
Mimicry (hide from predators)
Hierarchical social system (roles)
Life cycle reduces competition for food and living space

30. Insects: highly adaptive traits

31. Phylum Chordata: Invertebrates
Subphylum Urochordata
- The Tunicates : squat, thick-walled, protective tunic, live on ocean floor
Subphylum Cephalochordata
- Lancelets: small, knife-like, live buried in sediment near coast

32. Phylum Chordata
At some stage in their life cycle all chordates have the following:
A dorsal nerve chord
A notochord (rod of cartilage) running length of body
Gill slits in pharynx or throat

33. Vertebrate Chordates Class Chondrichthyes
Cartilaginous fish like sharks and rays
2. Class Osteichthyes
Bony fish like salmon, trout and tuna
3. Class Amphibia
Breathers in water and air like frogs

34. Vertebrate Chordates 4. Class Reptilia (creepers)
Most live in dry, hot areas – like snakes
5. Class Aves
Have feathers and hollow bones – birds
6. Class Mammalia
Have hair, and mammary glands - mammals
