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

REPTILES

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

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
