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).

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

~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
