Protozoa and Metazoa

In the  creature world ,there are 2 types of animals.  Metazoa and Protozoa.Protozoa are singular celled. Metazoa  are multi-cellular organisms such as   Homo sapiens or  humans. An example of Protozoa is a  Stentor . Here a picture of a Stentor.

 So you get the idea , right? Fish , snakes , cats , dogs , primates , birds , amphibians , dolphins , bats ,  bears , raccoons  ,  cows , goats , sheep , hyenas ,monotremes ( like the platypus ) ,are all    Metazoa and some Protozoa are :

Volvox
Euglena
Paramecium
Amoeba
Stentor

But the ones that came first were  Protozoa. If you want proof , Take a living sponge , put it in a blender and 
take it back to the sea . You might think its dead , but its not! Sometime later if you look, you will see its all rearranged.The reason this happened was because long ago the Protozoa decided to live together to make 

life  easier . By the way , if you want to see   Protozoa , just go to a wetland , or a swamp and scoop up some 
water and put it in a very powerful microscope .
So even though protozoa and metazoa  are very different,
 there still living organisims.
