Classification of Animals I can classify organisms based on common characteristics

Classification of Animals Scientists have divided the Animal Kingdom into two main groups: Vertebrates (animals with a backbone) and Invertebrates (animals without a backbone)

Animals with backbones can be divided into five more groups: Vertebrates Animals with backbones can be divided into five more groups: Mammals Birds Reptiles Amphibians Fish

Animals without a backbone. Invertebrates Animals without a backbone.

Animals with a backbone. Vertebrates Animals with a backbone.

Arthropods Body is divided into segments Crustaceans -Segmented body with a hard shell covering Insects -6 legs 3 body parts Arachnids -8 legs 2 body parts

Bodies are full of pores and channels that water circulates through Porifera Bodies are full of pores and channels that water circulates through Sponges

Have arms or spines that radiate from center of their body Echinoderms Have arms or spines that radiate from center of their body Sea Urchins and Starfish

Segmented Worms “Annelids” Bodies that are divided into segments earthworm

soft, skin-like organ usually covered with a hard outside shell Mollusks soft, skin-like organ usually covered with a hard outside shell oyster, mussel, clam, squid, octopus, snail

Mammals Give birth to live young. Feed their babies with their own milk. Are more or less covered with hair. Are warm-blooded.

Birds Have feathers. Lay eggs. Are warm-blooded.

Reptiles Are cold-blooded. Lay eggs. Have a dry skin covered with scales.

Amphibians Are cold-blooded. Lay eggs. Have a smooth, moist skin. Are able to live on land as well as in the water.

Fish Are cold-blooded. Lay eggs (but some do give birth to live young). Have a moist skin covered in scales. Breathe through gills.
