ANIMAL STRUCTURE AND LIFE CYCLE
Mrs. Krajewski
CHARACTERISTICS OF ANIMALS
CHARACTERISTICS:
1. made of cells 2. They reproduce 3. They move 4. They eat food 5. They grow and
change
VERTEBRATES VS. INVERTEBRATES
VERTEBRATES INVERTEBRATES
All animals that have backbones.
Fish, amphibians, retiles, birds, and mammals
All animals that do not have a backbone.
Arthropods- (insects, crabs, spiders)

WARM BLOODED VS. COLD BLOODED
WARM BLOODED COLD BLOODED
The body of a Warm Blooded animal does not change much.
The body of a Cold Blooded animal changes depending on their surroundings.
ANIMAL CLASSIFICATIONS
Animals are classified into different types of groups.:
To study the many forms of animal life in a systematic way, scientists have divided the animal kingdom into groups. These groups are largely based upon the structure of the animal's body. Information is from: http://kids.britannica.com/comptons/article-196401/animal
Insects Amphibians Mammals Reptiles Fish Birds

FISH
Fish are usually covered in scales. They live only in water. Fish breathe mostly by using their gills. Fish are cold blooded and most lay eggs.
There are three classes of fish:
1. the primitive jawless fishes, or Agnatha
2. the cartilaginous (shark like) fishes, or Chondrichthyes
3. the bony fishes, or Osteichthttp://answers.encyclopedia.com/question/three-classes-fish-

AMPHIBIANS
Amphibians are covered with a smooth skin
They can live on both land and in the water.
They breathe by using their gills or with lungs, sometimes even both!
They are cold blooded They hatch from eggs
REPTILES
Reptiles are covered in scales
Most reptiles live on land
Some can live in water They use their lungs to
breathe They are cold blooded They usually lay eggs
BIRDS
Birds are covered with feathers.
They usually live on land, but some spend a great deal of time on water
Birds breathe using lungs
They are warm blooded They lay eggs
MAMMALS
All mammals have hair or fur
Most live on land, but a few live in water
They use lungs to breathe Mammals are warm
blooded, they control their body temperature
Most mammals have live births
APPLY TO LEARNING Draw this chart in your copybook and
list whether each classification is cold blooded or warm blooded:

LIFE CYCLES OF ANIMALSAnimals have a variety of life cycles. Each life cycle depends on the species and can vary greatly. Let’s read pages 20 and 21 together!
