The Animal Kingdom

1. The Animal Kingdom

2. The most and least familiar to us Most people can name many animals yet more and more are being discovered every day, especially from very deep parts of the ocean. Due to new technology, robots are able to retrieve data and species never seen before.

3. Some newly discovered organisms:

4. How Many Phyla? Almost all of the animals we commonly think of -- mammals, fish, and birds – belong to one subphylum within one of the 33 Phyla comprising the Animal Kingdom

5. Around 800,000 species have been identified in the Animal Kingdom – most of them in the Arthropod phylum

6. AnimalsInvertebrate Chordates(Subphylum Vertebrate)

7. Invertebrate vs. Chordates Invertebrate: Do not have a spinal chord Chordates: Do have a spinal chord

8. Invertebrate Rule! Of the million or more animal species in the world, more than 98% are invertebrates.

9. Invertebrates:Most havea hard outer shell(exoskeleton) -insects and crustaceansVertebrates:havean internal skeleton made of bone, called an “endoskeleton”.-

10. Phylum Porifera: The Sponges The simplest invertebrate

11. Sponges are filter feeders, siphoning food particles out of the water.

12. Phylum Cnidarians: Stinging-Celled Animals coral polyps, hydra, jellyfish, sea anemone

13. Phylum Platyhelminthes – flatworms, planaria, flukes

16. Tapeworm Infestation

17. Phylum Nematoda: The Roundworms hookworms, pinworms, canine heartworms

18. Hookworms

19. An infected animal passes massive numbers of hookworm eggs in the feces, up to 28,000 per day! These eggs hatch into larvae which feed on the bacteria in the fecal matter surrounding them

21. About 1.3 billion people are infected with hookworms, which are intestinal roundworms. The infection is most common in tropical areas where sanitation is poor. Hookworms thrive in warm, moist places. Humans can become infected by contact with contaminated soil. The worms penetrate the skin and migrate locally in the skin instead of migrating to the lungs. Hookworm in Foot

22. Canine Heartworm Mosquitoes carry the immature worm, the “filaria”, that lives in the dogs’ blood, and spread it from dog to dog. The adult worms live in the heart and they block the blood flow.

23. Canine Heartworm in a dog’s heart that died because the heart couldn’t pump blood to the lungs and body.

24. Phylum Annelida – segmented worms(includes leeches and a type of marine worms)

25. Soils may harbor 50 to 500 earthworms per square meter; they keep soils aerated, and their castings fertilize the soil.

26. Most earthworms and leeches are hermaphroditic with both male and female gonads.

29. Phylum Mollusca (mollusks)

30. Class Gastropoda – snails and slugs

31. Class Bivalvia – clams, oysters, scallops, mussels

32. Class Cephalopoda – squid, octopus, nautilus

33. Phylum Arthropoda (arthropods)

34. Class Crustacea – crabs, lobster, shrimp

35. Class Arachnida – spiders, scorpions, ticks

36. Class Chilopoda – centipedes

37. Class Diplopoda – millipedes

38. Class Insecta – insects

39. Phylum Echinodermata: Animals with spiny skin

40. Phylum Chordata

41. Subphylum Vertebrata: The Vertebrate

43. Class Agnatha: Jawless Fish

44. Class Chondrichthyes – Cartilaginous Fish ‘(sharks, rays, chimeras)

45. Class Osteichthyes – bony fish

46. Class Amphibia “Double Life” -Egg to larvae to adult - Lay eggs in water -frogs, newts, salamanders

47. Class Reptilia • Lay eggs on land • - Lungs, scaly skin, leathery egg • Lizards, snakes, turtles, alligatiors, crocodiles

48. Class Aves – birds • Feathers • Lay eggs (hard shelled) • Many migrate • - Warm blooded

49. Class Mammalia

50. Subclass Monotremata:platypus & spiny anteater
