3.1 Study Guide
Name_____________________________ Block_______ Date____________
1. The Animal Kingdom is divided into how many different phyla?
35
2. What are the 2 groups in which we can classify these phyla?
Vertebrates and invertebrates
3. What are the 6 characteristics all animals share?
Bodies are multi-cellular; heterotrophs; obtain food and oxygen; keep internal conditions in balance
(homeostasis); they move; they reproduce
4. What are the 5 characteristics all vertebrates share?
Have backbones, muscles, and endoskeleton; blood circulates and have lungs or gills for breathing;
protective skin covering; legs, wings, or fins for movement; nervous system with brain that processes
information through sensory organs
5. What are the 5 main groups of vertebrates?
Mammals, birds, reptiles, amphibians, fish
6. If an animal is cold-blooded, what does that mean about its body temperature?
It changes to that of the animal’s environment
7. What does ectothermic mean?
Cold blooded
8. Which vertebrates are ectothermic?
Reptiles, amphibians, fish
9. Which vertebrates are ectothermic; obtain dissolved oxygen in water through gills; most lay eggs;
have scales; have fins; live in water?
Fish
10. Which vertebrates are ectothermic; most can breathe in water with gills as young, and breathe on
land with lungs as adults; go through metamorphosis; lay jelly-like eggs?
Amphibians
11. Which vertebrates are ectothermic; breathe with lungs; most lay eggs; have scales or plates; in
some, eggs hatch inside female?
Reptiles
12. If an animal is warm-blooded, what does that mean about its body temperature?
Its body temp stays constant regardless of the environment
13. What does endothermic mean?
Warm blooded
14. Which vertebrates are endothermic?
Mammals and birds
15. Which vertebrates are endothermic; breathe with lungs; most have babies born live; have hair or
fur; produce milk to feed their young?
Mammals
16. Which vertebrates are endothermic; breathe with lungs; lay eggs; have feathers; have a beak, 2
wings, and 2 feet?
Birds
17. Frogs, toads, and salamanders are from which vertebrate group?
Amphibians
18. What are the 5 main groups of invertebrates (we learned about)?
Echinoderms, Arthropods, Mollusks, Segmented worms, and Sponges
19. What are the 2 main characteristics all invertebrates share?
Do not have a backbone or internal skeleton; some have external skeletons called exoskeletons
20. Which invertebrates have jointed legs, segmented bodies, and some have wings?
Arthropods
21. Which invertebrates are very simple animals that have many pores through which water flows?
Sponges
22. Which invertebrates have arms that extend from the middle body outward and tube feet that take
in oxygen from the water and spines?
Echinoderms
23. Which invertebrates have long tube-like bodies that are divided into segments? They are also the
simplest organisms with a true nervous system and blood contained in vessels.
Segmented worms
24. Slugs, snails, clams, and octopuses are examples from which invertebrate group?
Mollusks
25. Sea stars, brittle stars, sea cucumbers, and sea urchins are examples from which invertebrate
group?
Echinoderms
26. Earthworms and leeches are examples from which invertebrate group?
Segmented worms (annelids)
27. Butterflies, spiders, and crabs are examples from which invertebrate group?
Arthropods
28. Chickens and ducks are examples from which vertebrate group?
Birds
29. Snakes and turtles are examples from which vertebrate group?
Reptiles
