Vertebrates / invertebrates:

Ask yourself one question?

"Does it have a backbone?"

VERTEBRATES

ALL HAVE: 

• Endoskeleton (& a backbone, made of vertebra)
• Muscles

How do we call animals without an endo- or exoskeleton?

How do we call animals with an exoskeleton?

5 CLASSES. Differences are based on ...

• Where do they live? Land, air, water, both? 
• How do they reproduce? Eggs (inside or outside of their bodies)? Are they livebearers?
• Cold-blooded or warm-blooded? 
• How do they breathe? Through gills, their skin or lungs?

SOMETIMES IT IS NOT SUPER CLEAR

Fish

-Live in water

-Have scales(schubben) covered in mucous(slijm). 

-Use gills(kieuwen) to breathe.

-Are cold-blooded.

-Lay eggs without a shell.

Amphibians

-Live in water and land.

-Have skin covered in mucous. 

-Use gills and skin to breathe when young. Lungs and skin when mature(volwassen).

-Are cold-blooded.

-Lay eggs without a shell.

Reptiles

-Live (mostly) on land.

-Have dry scales as skin. 

-Use lungs to breathe.

-Are cold-blooded.

-Lay eggs with a leathery shell.

Birds

-Live (mostly) on land and sky.

-Have feathers(veren). 

-Use lungs with air-sacs to breathe.

-Are warm-blooded.

-Lay eggs with a chalky(kalkachtig) shell.

Mammals

-Live (mostly) on land.

-Have fur (vacht). 

-Use lungs to breathe.

-Are warm-blooded.

-Give birth to live young.

-Feed young with milk.
