The Animal Kingdom

The Animal Kingdom. 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.

  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

  14. Tapeworm Infestation

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

  16. Hookworms

  17. 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

  18. 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

  19. 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.

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

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

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

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

  24. Phylum Mollusca (mollusks)

  25. Class Gastropoda – snails and slugs

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

  27. Class Cephalopoda – squid, octopus, nautilus

  28. Phylum Arthropoda (arthropods)

  29. Class Crustacea – crabs, lobster, shrimp

  30. Class Arachnida – spiders, scorpions, ticks

  31. Class Chilopoda – centipedes

  32. Class Diplopoda – millipedes

  33. Class Insecta – insects

  34. Phylum Echinodermata: Animals with spiny skin

  35. Phylum Chordata

  36. Subphylum Vertebrata: The Vertebrate

  37. Class Agnatha: Jawless Fish

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

  39. Class Osteichthyes – bony fish

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

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

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

  43. Class Mammalia

  44. Subclass Monotremata:platypus & spiny anteater
