KINGDOM ANIMALIA
![Page 2: Kingdom animalia](https://reader036.fdocuments.in/reader036/viewer/2022062300/558b4d2ed8b42a2d2a8b4790/html5/thumbnails/2.jpg)
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

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
