Kingdom Animalia
~ Characteristics ~
Multi-cellularEukaryotic 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 toCharacteristics 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.

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
~InvertebratePhylum 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 legswell 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 antennae3 pairs of legs2 body regions - head, thorax & abdomen
grasshoppers, ants, butterflies, bees
~ Phylum Chordata ~ subphylum Vertebrata
