Kingdom Animalia

Eukaryotic with no cell walls Heterotrophs (consumers) ~ Characteristics ~ Multi-cellular Eukaryotic with no cell walls Heterotrophs (consumers) motile

Characteristics Cont. Animal Movement Motile, mobile Most animals are capable of complex and relatively rapid movement compared to plants and other organisms.

Animal Reproduction Most animals reproduce sexually, by differentiated haploid cells (eggs & sperm). Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material.

Characteristics of Life 1. Living things are organized. 2. Living things are made up of cells. 3. Living things metabolize. 4. Living things maintain an internal environment. 5. Living things grow. 6. Living things respond. 7. Living things reproduce. 8. Living things evolve.

Animal Sizes Animals range in size from no more than a few cells to organisms weighing many tons blue whale a mesozoan

Animal Habitats Most animals inhabit the seas, with fewer in fresh water and even fewer on land.

Animal Cell Diagram

Animal Bodies The bodies of most animals are made up of cells organized into tissues. Each tissue is specialized to perform specific functions. Cells->tissues->organs->organ sys >organism

Animal Symmetry Describes how animal body structures are arranged Allows animals to move in different ways Cnidarians and echinoderms are radially symmetrical. Most animals are bilaterally symmetrical.

Symmetry: The most primitive animals are asymmetrical: No symmetry

Radial Symmetry forms that can be divided into similar halves by more than two planes passing through it. Animals with radial symmetry are usually sessile, free-floating, or weakly swimming.

Radial Symmetry

Bilateral Symmetry Animals with bilateral symmetry are most well-suited for directional movement.

Bilateral Symmetry

95% of all animals are in this group ~Invertebrates~ No backbones 95% of all animals are in this group

~ Protection and Support ~ exoskeleton – a hard, waxy coating on the outside of the body endoskeleton – support framework within the body

~Invertebrate Phylum Porifera~ Sponges simplest form of animal life live in water Do not move around no symmetry 5000 species

~Invertebrate Phylum Porifera~ Examples: Tube Sponge, Glass Sponge, Sea Sponge

~Invertebrate Phylum Cnidaria~ Live in water Most have tentacles catch food with stinging cells gut for digesting

~Invertebrate Phylum Cnidaria~ 2 different shapes Medusa - like a jellyfish Polyp - like a hydra

~Invertebrate Phylum Cnidaria~ Examples - Jellyfish, Hydra, sea anemones, and corals

~Invertebrate Phylum Mollusca ~ Soft bodies Hard Shells Live on land or in water have a circulatory system and a complex nervous system. Important food source for humans

~Invertebrate Phylum Mollusca ~ Class Gastropoda snails and slugs may have 1 shell stomach-footed - move on stomach

~Invertebrate Phylum Mollusca ~ Class Bivalves 2 shells hinged together clams, oysters, scallops and mussels

~Invertebrate Phylum Mollusca ~ Class Cephalopods squids and octopuses internal mantel

~Invertebrate Phylum Platyhelminthes: worms ~ Flatworms Example: Planaria, tape worms Flat, ribbon-like body Live in water or are parasites lives in intestines of host absorbing food bilateral symmetry Regeneration- regrow body parts

~Invertebrate : Flat WORMS Cont.~ eyespots detect light scavengers & predators lives in intestines of host absorbing food food and waste go in and out the same opening

Examples of flat worms

~Invertebrate Phylum Annelida ~ Are Segmented worms Have Body divided into segments (sections) Live in water or underground have a nervous and circulatory system

~Invertebrate Annelida Cont~ Earthworms eat soil and breakdown organic matter, wastes provide nutrients to soil

More annelids: segmented worms leeches parasites that feed on blood of other animals

~Invertebrate Phylum Arthropod ~ Body divided into sections/segments Exoskeleton – outer Molt – shed exoskeletons as they grow Jointed appendages (legs) well developed nervous system largest group of organisms on earth

~Invertebrate Phylum Arthropod ~ Include the classes: Crustaceans, arachnids, centipedes, millipedes, and ***Class insecta Classified into classes according to the number of legs, eyes and antennae they have.

~Invertebrate Phylum Arthropods~ Insects- 3 body sections Head – antenna Thorax – midsection (wings and legs) Abdomen – (internal organs/structures) grasshoppers, ants, butterflies, bees

~ Phylum Chordata: Vertebrata~ 5 classes Fish Mammals Reptiles Amphibians Birds

Fish Are cold-blooded Have gills and scales Live in water Have a Backbone

These are Fish:

Fish have Backbones

Reptiles: Have scales Live on land Are cold-blooded Usually lay eggs Have a Backbone

These are Reptiles Crush!!!

Reptiles have Backbones

Amphibians Live in water and on land Have smooth skin Lay eggs Have a Backbone Are cold blooded Have smooth skin

These are Amphibians These are Amphibians

Amphibians have Backbones

Birds Have feathers Are warm-blooded Have hollow bones and most can fly Lay eggs Have a Backbone

These are Birds

Birds have Backbones

Mammals Have hair or fur Are warm-blooded Feed milk to their young Bear live young (except monotremes) Have a Backbone

These are Mammals

Mammals have Backbones
