Body Symmetry of Animals Information to know Body Symmetry of Animals

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

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

Asymmetry cannot be divided into mirror images

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

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

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

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.

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

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

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

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

Animals without a backbone. Invertebrates Animals without a backbone.

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

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

The 9 Phyla of Kingdom Animalia 9. Phylum Chordata

Insects & Arthropods https://www.youtube.com/watch?v=-jNNvjJkLoc

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

Phylum Arthropoda

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

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

Insects: highly adaptive traits

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

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

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

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
