8. What is Zoology? The study of animals

9. What it means to be an animal Kingdom Animalia

10. Animals are everywhere How many are there?

11. Animals are everywhere How many are there? –1.5 million species of animals described –E.O. Wilson (1986) estimated 5-30 million spp. exist

12. Unusual habitats include

15. Your facial hair follicles: mites Caves: amphipods, fishes Deep rift vents: worms, mussels Hot springs: ciliates Moss on trees: tardigrades Beer coasters: nematodes

16. What does the average animal look like? Cute and fuzzy right?

17. What does the average animal look like? Cute and fuzzy right? No, actually the average animal looks quite different

19. What animal is this?

22. Hallucigenia sparsa an Onychophoran from the Burgess Shale deposits of Canada

23. Fossils have been found in the Middle Cambrian marine faunas.

25. Lengths of AnimalApprox. Number of Species Less than 0.01 inches20,000 0.01 to 0.1 inches220,000 0.1 to 1.0 inches600,000 1.0 to 10.0 inches20,000 10.0 to 100.0 inches1,500 More than 100 inches 10

26. So, the average animal is: Crunchy: coleopterans (exoskeleton) Buzzy: dipterans, hymenopterans Slimy: mollusks, nematodes Scaly: lepidoptera Tiny: all of the above Not really cute and fuzzy at al, huh?

27. Lots of Animals have intimate associations!

28. Western chorus frog, Pseudacris triseriata, coccidia. 3 OW SR SB SR SR 1 2 SB

29. Isospora cogginsi (Bolek et al. 2003)

30. Eimeria streckeri (Upton and McAllister 1988)

32. Cricket Frog from Pawnee Lake Nebraska

40. Evolution and Classification of Animals Animals probably evolved from marine protists, although no group of protists has been identified from an at-best sketchy fossil record for early animals. Cells in primitive animals show similarities to collared flagellates as well as pseudopodia producing amoeboid cells.

41. Today’s Animals Modern animals are classified into between 30 and 36 phyla All major modern phyla were present at the beginning of the Cambrian (590 MYA) Of the animal phyla, scientists consider nine major invertebrate phyla to be of major importance in therms of biological diversity
