1. Explain how animals defend themselves

2. Structures of Animals
6-3.2 Summarize the basic functions of the structures of animals that allow them to defend themselves, to move, and to obtain resources.

3. Structures for Defense
What structures do animals have to defend themselves from predators?

4. Structures for Defense
Animals hide from or warn predator.
Ex: skin color (camouflage) or patterns (mimicry)

5. What is Mimicry?
Animal copies appearance, actions, or sounds of dangerous animal. AKA MIMIC or Copycat
Ex: Bumblebees (with stingers) and Robber Flies (which also make a sound similar to a bee).

6. Structures for Defense
Animal makes a direct, painful attack.
Ex: horns, claws, quills, stingers, venom

8. Structures for Defense
Animal changes size to prevent attack
Ex: shells, emitting smells or body fluid (ink)

10. Structures for Defense
Animal flees or hides.
Ex: Body Design
Sensory organs
Legs (speed/jumping)
Wings
Light-weight skeletons (flight)

11. Structures for Defense
Animal uses holes or tunnels to hide or climb away
Ex: paws or toenails

12. Structures for Movement
What structures allow animals to move to fulfill their needs, such as finding food and escaping predators?

13. Structures for Movement
Legs
Feet and arms
Tails
Fins
Wings
Body design
Skeleton

14. Structures to Obtain Resources
What specialized structures do animals have in order to obtain food?
What structures do animals have that we (as humans) don’t have?

15. Structures to Obtain Resources
Animal chews, tears, and eats its food or drink.
Ex: mouth parts
Beaks
Teeth
Flexible jaws
Tongues
Tube-shaped mouths

17. Structures to Obtain Resources
Animal grabs and holds food
Ex: tentacles, pincers, claws, fangs

18. Structures to Obtain Resources
Animal consumes food in water
Ex: filtering structures
Sponges
Clams

19. Give two examples of how animals use camouflage for different reasons.
