1. Animal Kingdom
By: Victoria Estes

2. Animal Kingdom
 Many celled organisms
 Move from place to place (most can)
 Divided into two major groups
 Vertebrates
 Invertebrates

3. Vertebrates
 Animals with backbones
 Broken down into 5 main groups
1. Mammals
2. Birds
3. Fish
4. Reptiles
5. Amphibians

4. Mammals
 Warm-blooded
 Have hair or fur
 Born alive
 Classified into 3
groups based on how
they produce young
(babies)

5. Mammals Continued
1. Placental Mammals – until they are
born the animal develops inside the
mother’s body
2. Marsupials – young are born before
they are fully developed and move into
a pouch to get mild until fully developed
3. Lay eggs – only two animal species
1. Duckbilled platypus
2. Spiny anteater

6. Birds
 Warm-blooded
 Have feathers
 Lay eggs

7. Fish
 Cold-blooded
 Scales
 Gills
 Fins
 Lay eggs

8. Reptiles
 Cold-blooded
 Scales
 Lungs
 Generally live on
land

9. Reptiles Continued
 3 major groups
 Snakes and lizards
 Use their tongues to smell and detect body heat
 Turtles/Tortoises
 Have shells and a complete skeletal system with
a backbone
 Toothless
 Crocodiles/alligators

10. Amphibians
 Cold-blooded
 Smooth skin
 Live part of their lives
on land and part in
water

11. Amphibians Continued
 Classified into two
groups
 Group 1 – without
tails
 Frogs and toads
 Group 2 – Have tails
 Salamanders and
Newts

12. Invertebrates
 Animals without backbones
 Broken down into four main groups
1. Ringed worms
2. Echinoderms
3. Mollusks
4. Arthropods

13. Ringed Worms
 Cold-blooded
 Soft body with
sections
 3 types of worms
 Examples:
 Leeches
 Clamworms
 Earthworms

14. 3 Types of worms
1. Flat worms
 They are flat
 Many are parasites
 Example: tapeworm
1. Roundworms
 May cannot be seen without a microscope
 Tapered bodies
 Have a full digestive system
 Some can be more than one meter long
1. Segmented worm
 Made up of separate sections or segments
 Complex body structure (digestive system, circulatory
system and nervous system)
 Example: earthworm - bristles on body help it move through
the soil

15. Echinoderms
 Cold-blooded
 Rough skin
 Sharp spines
 Examples:
 Sand dollars
 Sea urchins
 Starfish

16. Mollusks
 Cold-blooded
 Soft body
 Sometimes a hard shell
 Examples:
 Squid
 Snails
 Clams
 Oysters
 Octopuses

17. Mollusks Continued
 Soft-bodied animals that have a protective
covering, or tissue, called a mantle
 Three categories
1. Bivalve – two shells hinged together
 Live in salt water
 Examples: Oysters, clams, scallops, mussels
1. Univalve – One shell
 Examples: snails, slugs
1. Cephalopods – has a shell on the inside of its
body or no shell
 Examples: squid, octopus

18. Arthropods
 Cold-blooded
 Jointed legs
 Exoskeleton
 Examples:
 Insects
 Spiders
 Lobsters
 Crabs

19. Arthropods Continued
 Arthropod means “jointed leg”
 Has a body made up of segments with jointed
legs and an exoskeleton
 Exoskeleton – a hard outer covering or
skeleton on the outside of the body
 Arthropods shed their skeleton and form a new one
in a process called molting
 There are more different kinds of arthropods
than all other types of animals put together!
