Kingdom animalia

kingdom animalia

1. KINGDOM ANIMALIA

2. CHARACTERISTICS Far more diverse than Kingdom Plantae Consist of the most complex organisms consisting of about 2 million species Heterotrophic, multicellular eukaryotes belongs to this kingdom Vary in size – ranging from microscopic to the most gigantic creatures

3. Kingdom Animalia are divided into 2 groups 1. Vertebrates - animals with backbones 2. Invertebrates - animal without backbone

4. VERTEBRATES MAMMALS - covered with hair and they have mammary glands - these gland secrete milk of females who have just delivered their young - warm-blooded animals Ex. Cats, dogs, goat, whales and dolphins

5. MAMMALS

6. VERTEBRATES 2. BIRDS -feathers cover their body - they have beaks or bill which they used to get food - they have a pair of wings that enable them to fly - they are also warm blooded animals that lay eggs from which their young is hatched

7. BIRDS

8. VERTEBRATES 3 . REPTILES -they have thick, dry scales that cover the bodies of reptiles to prevent the excessive loss of water - they are cold blooded animals - some have four legs, while others have no legs at all

9. REPTILES

10. VERTEBRATES 4. AMPHIBIANS - live in water during the early stage of their life and begin to stay on land where they can get enough food - body is covered by a thin, flexible and usually moist skin - their eggs are fertilized externally

11. AMPHIBIANS

12. VERTEBRATES 5. FISHES - they have scales as body covering and they breathe through the gills - they also have lungs for breathing - bangus , lapu-lapu and dalagang bukid are all bony fishes - sharks and rays are cartilagenous fishes

13. FISHES

14. INVERTEBRATES PHYLUM ECHINODERMATA - marine organisms with spiny skins - from the Greek terms echinos (meaning hedgehog) and derma (meaning skin) - the tube feet and system of canals in the body that serves as a channel for sucking in the sea water to obtain nutrients and for vomiting sea water

15. ECHINODERMS

16. ECHINODERMS

17. INVERTEBRATES 2. PHYLUM ARTHOPODA - they have a pair of 3 or more jointed legs - from the Greek term arthron ( meaning joint) and podus (meaning foot) - they have an exoskeleton or hard outer body covering made up of chitin - the largest phylum in kingdom Animalia

18. ARTHROPODS

19. INVERTEBRATES 3. PHYLUM MOLLUSKA -they have soft body - from Latin term mollis , which means soft - most have protective shells as the outer covering

20. MOLLUSKS

21. INVERTEBRATES 4. PHYLUM ANNELIDA -characterized by ringlike body parts - they are worms with segmented body - they have a mouth at the front and anus at the tail end of their bodies - they have hearts and blood vessels that constitute a circulatory system

22. ANNELIDS

23. INVERTEBRATES 5. PHYLUM NEMATODA - roundworms are cylindrical worms with a finely tapered tail - the body is covered with a tough, non living skin that resist drying and crushing

24. INVERTEBRATES 6. PHYLUM PLATYHELMINTHES - the simplest worm - some of them are free living while others are parasitic, living in the bodies of animals including humans

25. FLATWORMS

26. INVERTEBRATES 7. PHYLUM CNIDARIA - posses stinging structures called nematocysts in their tentacles - characterized by a hallow, tube like bodies, with a mouth at the end

27. CNIDARIANS

28. INVERTEBRATES 8. PHYLUM PORIFERA - pore-bearing organisms - they may live singly or in colonies - they eat by allowing water to flow through their bodies and trapping small organisms in the water using their specialized cells

29. PORIFERANS
