Animal classification (slideshare version - no hyperlinks)
- 1. Animal Classification What makes a fish a fish? Do all birds fly? How do we organize animals into different groups?
- 2. What is animal classification? • Animal classification is how animals are sorted into groups based on common characteristics. • The groups are arranged from general characteristics (for example, whether an organism is single-celled or multiple-celled) to specific (for example, whether a duck can dive or not). http://en.wikipedia.org/wiki/File:Biological_cla ssification_L_Pengo_vflip.svg
- 3. Kingdom Animalia • The animal kingdom is the kingdom that we belong to. • Each member of the animal kingdom: – Is made up of many cells – Eats other organisms to get energy – Can move its body – Reacts to stimuli http://hyperphysics.phy- astr.gsu.edu/hbase/biology/animal.html
- 4. Phylum • The next level of organization after kingdom. • Organized by body structure (symmetry, segmentation). • There are 35 phyla within the animal kingdom. • Includes vertebrates, or animals with backbones, and invertebrates, which do not have backbones. http://waynesword.palomar.edu/trnov01.htm
- 5. Classes • There are five main classes of vertebrates in the animal kingdom: – Mammals – Birds – Reptiles – Amphibians – Fish
- 6. Mammals • Best-developed brain • Warm-blooded • Live birth • Has fur or hair • Drinks milk • Maternal care Photo courtesy of Clip Art
- 7. Which of these would be classified as a mammal? • Red-winged blackbird • Bobcat • House fly • Goldfish
- 8. If you said a bobcat, you are correct!
- 9. Mammals you might find in Michigan: • Little Brown Bat • Whitetail deer • Beaver Other interesting mammals: • The duck-billed platypus and the echidna are the only mammals that lay eggs. • Bats are the only mammals that can fly!
- 10. Birds • Warm-blooded • Feathers • Beaks • Lays eggs • Flight (usually!) • Hollow bones Photo courtesy of Clip Art
- 11. A bird’s active part in breathing is the exhale (breathing out). True or False?
- 12. True! Unlike humans, birds must consciously breathe in, while their exhale occurs without effort.
- 13. Michigan birds: • Pileated woodpecker • Mallard duck • Common loon • Eastern bluebird Other interesting birds: • Emus, ostriches, and penguins cannot fly. • The northern shrike impales its larger prey upon thorns for ease of eating. • An owl compensates for its immovable eyes by rotating its head almost completely around.
- 14. • Cold-blooded • Scales as skin covering • Claws • Lay eggs (although some snakes do give live birth!) Photo courtesy of Clip Art
- 15. Because reptiles are cold-blooded, they cannot survive the cold Michigan winters. True or False?
- 16. False! Many reptiles sleep through the winter in a state called brumation. http://en.wikipedia.org/wiki/Dormancy#Brum ation
- 17. Michigan reptiles: • Garter snake • Hognose snake • Five-lined skink (the only lizard in Michigan) Other interesting reptiles: • The corn snake has a false rattle that it uses as a defense mechanism. • The king cobra lays its eggs in a nest. http://nationalzoo.si.edu/Animals/ReptilesAm phibians/Facts/default.cfm
- 18. Amphibians • Cold-blooded • Breathe through their slimy skin • Live in water or moist habitat http://www.flickr.com/photos/10438912@N 07/8084268885
- 19. An example of an amphibian is: • A lizard • A vampire • A salamander • A rabbit
- 20. A salamander is correct.
- 21. Amphibians you might find in Michigan: • Red-backed salamander • Green frog • Spring peeper • American toad Other interesting amphibians: • The barking tree frog has a call that sounds like a bark. • The red-backed salamander has a home range of just 24 meters. http://www.tnaqua.org/OurAnimals/Amphibians.aspx?gclid=CNL1qPSO_7ICFegWMgodWnEA6A http://amphibiaweb.org/cgi/amphib_query?where-genus=Plethodon&where-species=cinereus
- 22. Fish • Cold-blooded • Live in water • Have scales • Breathe using gills Courtesy of Clip Art
- 23. Fish cannot control how close they are to the surface of the water – they must depend on the waves to bring them deeper or shallower. True or False?
- 24. False! Fish control their level of depth by inflating or deflating their air bladder, which allows them to float (when inflated) or sink.
- 25. Michigan fish: • Rainbow trout • Bluegill • Large-mouth bass • Northern pike Other interesting fish: • The Sharpnose Puffer inflates itself to appear larger and more formidable. • The Mushroom Scorpionfish is covered in venomous spines. http://www.seasky.org/reeflife/sea2h.html
