KINGDOM ANIMALIA
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
Kingdom Animalia are divided into 2 groups
1. Vertebrates
- animals with backbones
2. Invertebrates
- animal without backbone
VERTEBRATES
1. 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
MAMMALS
VERTEBRATES2. 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

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

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
AMPHIBIANS
VERTEBRATES5. 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
FISHES
INVERTEBRATES
1. 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
ECHINODERMS

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
ARTHROPODS
INVERTEBRATES
3. PHYLUM MOLLUSKA
-they have soft body
- from Latin term mollis, which means soft
- most have protective shells as the outer covering
MOLLUSKS
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
ANNELIDS
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
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
FLATWORMS
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
CNIDARIANS
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
PORIFERANS
