Animal Kingdom

1. ANIMAL
KINGDOM

2. Characteristics of all Animals
• They are made of cells, which form
tissues, which form organs which form
organ systems.
• They obtain food by eating other
organisms (herbivores, carnivores or
omnivores).
• Most animals reproduce sexually but
some can reproduce asexually.

3. •All animals
move in order to
satisfy 1 of their
basic needs
(food, water,
shelter, escaping
danger)

4. Types of food eaters
Carnivore -
meat eater
(either a
predator - prey
relationship or
a scavenger)
Herbivore -
plant eater
Omnivore
- eats
plants and
meat

5. Division of animals

6. Animals have bilateral
symmetry (1 line that
can divide the animal
into 2 identical parts)
or radial symmetry
( many lines that can
divide the animal into
equal parts).

7. Sub Kingdom: Invertebrates
• Sponges
• Cnidarians
• Worms

8. Sponge
• Simplest form of animal
• No tissues or organs
• heterotrophic & cells
that have specialized
jobs
• Bodies pierced all over
with openings called
pores

9. How do
Sponges eat &
breathe?
• Collar cells on the
inside of central
cavity trap
bacteria & protists
& digest them.
• Sponges get O2 by
diffusion.

10. Cnidarians
• Specialized tissues - no organs.
• Radial symmetry

11. Digestion
• Capture prey using stinging cells to inject
venom - paralyzes prey
• Pull prey into mouth, digest in body cavity
digestive system: 1 opening - expel food
from mouths also.

12. Reproduction
• asexually by budding &
sexually.
• Some have both sexes
within 1 individual others
in separate individuals.
• Examples include
jellyfish, sea anemones
and coral.

13. Worms
• Flatworms (Platyhelminthes)
• Roundworms (Nematoda)
• Segmented worms (Annelida)

14. All Worms…
• Have tissues, organs and organ
systems.
• Have bilateral symmetry.
• Have a brain.
• Reproduce both sexually and
asexually.
• Can replace parts by a process called
regeneration.

15. PHYLUM MOLLUSCA
Clams, snails, squid, octopus

16. Most mollusks have a hard shell
covering their soft bodies.
Clams have a wedge-shaped muscular
foot used for locomotion.

17. PHYLUM CHORDATA
Fish, amphibians, reptiles, birds, mammals

18. Members of Phylum Chordata have a
backbone (they are vertebrates).

19. Class Chondrichthyes includes fish
whose skeletons are made of cartilage,
such as sharks, rays, and skates.
Fish

20. Class Osteichthyes includes fish whose
skeletons are made of bone.

21. Class Amphibia includes semi-aquatic
animals with moist skin. They must
return to the water to breed.
Amphibia

22. Class Reptilia includes snakes, lizards,
turtles, crocodiles, and iguanas.
They have dry, scaly skin.
Reptiles

23. Members of Class Aves have wings and
feathers for flight.
Birds

24. Class Mammalia includes animals with
hair or fur. Females have mammary
glands to nurse their young with milk.
Mammals
