1. Kingdom Animalia Notes Chapter 12

2. What do these have in common?

3. Animals are:
Multicellular eukaryotes
Heterotrophic (consumers)
Reproduce sexually (usually)
Develop from embryos
Have specialized parts
Are able to move (most)

4. True or False:
Almost all animals reproduce sexually.

5. Animals with a backbone and a skull are
called vertebrates they make up only
3 – 5 % of all animals
Animals without a skull and backbone are called invertebrates they make up 95 – 97% of all animals

6. ______________ make up 95 – 97% of all animals on Earth.
a. Vertebrates
b. Invertebrates
c. Mammals
d. Insects

8. Innate behaviors (NOT learned) are. influenced by genes – an animal is
Innate behaviors (NOT learned) are . influenced by genes – an animal is born KNOWING how to do something….

9. While learned behaviors have to be
taught or observed –

10. Speech is innate in humans, but the
particular language (English,
French….) you speak is learned.

11. What type of behavior is flying for a bird, or swimming for a fish?
A. Learned
B. Innate

12. Animals have THREE body plans:

13. (( sym = together and metry = measure))
Animals have three types of body plans:
1. bilateral symmetry (bi = 2)
2. radial symmetry (radial = positioned around a central point)
3. asymmetrical ( a = no, not)
(( sym = together and metry = measure))

14. Simple Invertebrates:
Sponges are asymmetrical. Have no head, nerves or stomach. Live in water
and can regenerate. They use collar
cells to filter H2O & eat.

15. Sponge:

16. Cnidarians – have radial symmetry and stinging cells to capture prey and defend themselves. Jellyfish, hydra and sea anemones are examples.

17. CNIDARIANS
JELLYFISH HYDRA SEA ANEMONE

18. Flatworms – simple worms with bilateral symmetry
Flatworms – simple worms with bilateral symmetry. Planarians, flukes and tapeworms are examples

19. Examples of Flatworms:
Planaria Tapeworms Flukes

20. Roundworms – most of these simple worms are parasites - examples
Roundworms – most of these simple worms are parasites - examples include: pinworms and hookworms

21. Roundworm Examples:
Pinworms Hookworms

22. Most of these simple invertebrates are parasites.
A. Cnidarians
B. Flatworms
C. Roundworms
D. Vertebrates

23. Complex Invertebrates:
Mollusks are the second largest
phylum of animals. They all have a foot, visceral mass, mantle and a shell.
Examples of mollusks: clam,
squids and snails

24. Mollusk Examples:
Clam Squid Snails

25. Annelid Worms – these are. segmented worms – like an
Annelid Worms – these are segmented worms – like an earthworm, bristleworm and leeches

26. Earthworms

27. Arthropods: Arthropods are the largest group
of animals on the Earth. 75% of all animals are arthropods.
Estimates:
Humans on Earth = 6 billion
Arthropods Earth = 10 billion billion

28. Characteristics of Arthropods:
jointed limbs
segments & specialized parts
exoskeletons
well-developed brains

29. Kinds of Arthropods:
1. centipedes & millipedes crustaceans (lobster & crab…) arachnids (spiders & ticks…) insects (bees, flies, moths…)

30. Centipede and Millipede

31. Echinoderms means “spiny skinned”,
these animals live on the ocean floor. Sea stars, sea cucumbers and sand dollars are examples

32. Echinoderms: Sea Cucumbers Sand Dollars Star Fish

33. This is the largest group of animals on Earth – they make up more than 75% of all members of the animal kingdom.
A. Arthropods
B. Echinoderms
C. Mollusks
D. Annelid Worms
