How Animals Live?
How do different animals live, grow, and change?
All animals need water, oxygen, food, and shelter Animals can be classified, or divided, into two groups.
Those that have a backbone. Those that don’t have a backbone.
A backbone is a series of bones that run down the back of some animals.
An animal that has a backbone is called a vertebrate
Classifying Vertebrates
A body feature passed on toan animal from its parents is calleda trait. Traits can include things an
animal does.
A Vertebrate such as this horse has a skeleton inside its body.
What is the series of bones that runs down
my back called?
A. Root stem
B. backbone
C. Vertebrate
Vertebrates can be classified into several smaller groups. One of these groups is the mammal group. A mammal is an animal that has hair/fur and produces
milk for its young. They need oxygen, a gas in the air, to live and they
breath the air with their lungs. Most mammals have a thick coat of hair or fur that
Traps air against their body for warmth.
Mammals
Sea lions are mammals that live both in water and on land. Even Mammals that live in water have lungs and most breath air.
What are two traits ofMammals?
A bird is a vertebrate that has feathers, wings, and two legs.
Birds lay eggs that have hard shells.
Most birds can fly.
Feathers keep a bird warm, but are light so they do not
weigh the bird down.
Birds
Bird of Paradise are found in western Indonesia, Papua New Guinea, and eastern Australia. The members of this family are perhaps best known for the plumage of the males of most species.
How are the bodiesof mammals and birds alike and
different?
Fish are vertebrates that live in water.
Fish have long, narrow bodies that make it easy to move
through water.
Fish are vertebrates that live in water.
Most fish are covered with scales that protect them.
Like all animals fish need oxygen to live, but they don’t
have lungs. Instead they breath through gills.
Fish
All fish have backbones. Sharks and Rays have backbonesMade of cartilage, a material that is softer than bone.
What are two traits of fish?
An amphibian is a vertebrate that starts life in water and
then lives on land as an adult.
Amphibians lay eggs in water and their young breath
through gills and have tails to help them swim.
As the young grow, their bodies change. Lungs and legs
grow and gills disappear.
After an amphibians body changes, they live on land.
Amphibians
Frogs have wet, smooth skin. Wet skin prevents their bodies from drying out on land.
An animal lives in water, has fur, and breatheswith lungs. Would you
classify it as a bird,a mammal, a fish, or an amphibian?
A reptile has dry, scaly, skin and lays eggs on land.
The scales protect them from the hot sun
Reptiles can live in many different environments.
Some use legs to move, others slither on the ground.
All reptiles breath with lungs and reptiles that spend a lot
of time in water must stick their noses out to breath.
Reptiles
Why do alligators and crocodiles
have to stick their noses out
of the water?
Directions: If you think the animal is a mammal, circle it. If it’s a fish, put an X through it. If you think it’s a bird, box it. If you think it is a reptile, triangle it.
Animal Classification
Game
Animals without a backbone
includes sea stars, butterflies, and spiders
Many invertebrates are very small
a soft sac filled with liquid supports worms and sea jellies
Insects and other arthropods have a hard covering on the
outside of their bodies.
Invertebrates
Major Kinds of Invertebrate Animals
Directions: If you think the animal is a sea jelly, circle it. If it’s a worm, put an X through it. If you think it’s a Mollusk, box it. If you think it is a arthropod, triangle it.
