Kingdom Animalia

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

Characteristics Cont. Animal Movement  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.

In addition to 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 (like the mesozoans) to organisms weighing many tons (like the blue whale ). a mesozoan blue whale

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

Animal Cells  Animal cells, are eukaryotic  Animal cells lack the rigid cell walls that characterize plant cells.

Animal Cell Diagram

Animal Bodies  The bodies of most animals (all except sponges) 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

~ Protection and Support ~  not all animals have a skeleton, divided into 2 groups: exoskeleton – a hard, waxy coating on the outside of the body endoskeleton – support framework within the body

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

~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 Platyhelminthes ~  Flatworms  Flat, ribbon-like body  Live in water or are parasites  bilateral symmetry

~Invertebrate Phylum Platyhelminthes ~  Examples: Planaria  eyespots detect light  food and waste go in and out the same opening

~Invertebrate Phylum Platyhelminthes ~  Examples: Tapeworm  Parasite that lives in intestines of host absorbing food

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

~Invertebrate Phylum Annelida ~  Class Earthworms  eat soil and breakdown organic matter, wastes provide nutrients to soil

~Invertebrate Phylum Annelida ~  Class leeches  parasites that feed on blood of other animals

~Invertebrate Phylum Arthropoda ~  Body divided into sections/segments  Exoskeleton  Jointed legs  well developed nervous system  largest group of organisms on earth

~ Invertebrate Phylum Arthropoda ~  3 subphylums:  Classified into classes according to the number of legs, eyes and antennae they have.

~Invertebrate Phylum Arthropods ~ Subphylum Uniramia  Class Insecta no antennae 3 pairs of legs 2 body regions - head, thorax & abdomen grasshoppers, ants, butterflies, bees

~ Phylum Chordata ~ subphylum 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

Reptile s:  Have scales  Live on land  Are cold-blooded  Usually lay eggs  Have a Backbone

These are Reptiles Crush!!!

Reptiles have Backbones

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

 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
