1
Kingdom Animalia
2
Basic Characteristics
Multicellular Eukaryotic Heterotrophic Mostly motile (few exceptions) Primarily sexual reproduction but some asexual.
3
Nutrition Organisms in the kingdom Animalia are heterotrophs.
Some organisms are herbivores, carnivores and omnivores.
4
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
5
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.
6
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
7
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
8
The 9 Phyla of Kingdom Animalia
1. Phylum Porifera 2. Phylum Cnidaria 3. Phylum Platyhelminthes 4. Phylum Nematoda pinworm
9
The 9 Phyla of Kingdom Animalia
5. Phylum Annelida 6. Phylum Mollusca 7. Phylum Echinodermata 8. Phylum Arthropoda
10
The 9 Phyla of Kingdom Animalia
9. Phylum Chordata
11
Phylum Arthropoda Habitat: terrestrial, aquatic, air
Symmetry: bilateral Body cavity: coelmate Reproduction: sexual Motile Organization: body systems Digestion: extracellular Fertilization: internal
12
Phylum Arthropoda
13
Arthropoda: Success and Diversity
Exoskeleton: protection Body Segments Nervous System: larger brains Nutrition process: can obtain food in many ways
14
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
15
Insects: highly adaptive traits
16
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
17
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
18
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
19
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
