YOU TOUCH ON TWO VERY DIFFICULT GROUPS. I HAVE WRITTEN A GENERAL 
INTRODUCTORY GUIDE TO PROTOZOA (MY CREDENTIALS FOR ANSWERING THIS MISSIVE)

 
FOR GUIDANCE I NEED TO KNOW WHERE YOU STAND NOW.  WHICH BOOKS DO YOU USE 
FOR GUIDANCE.

AMOEBAE WILL REQUIRE CULTURES, AND IF YOU CANNOT DO THIS STAY CLEAR OF 
AMOEBAE.  THE RIGHT BOOKS ARE THE PAGE BOOKS OR THE PAGE/SIEMENSMA BOOK.

REGARDING FLAGELLATES.  MOST PEOPLE CANNOT TELL BODO FROM A HOLE IN THE 
GROUND.  MOST ACCOUNTS OF 'BODO EDAX' ARE NOT OF THIS ORGANISM.  THERE 
ARE ONLY A FEW BODOS WHICH CAN BE IDENTIFIED WITH SOME EASE.  MOST 
ORGANISMS ASSIGNED TO THIS GENUS ARE NOT BODO'S.  DO YOU HAVE A COPY OF 
PATTERSON AND LARSEN (THE BIOLOGY OF FREE-LIVING HETEROTROPHIC 
FLAGELLATES) AS THIS WILL PROVIDE YOU WITH GUIDANCE TO ALL GENERA AND TO 
THE LITERATURE FOR FURTHER WORK.  

HOWEVER, IF YOU WANT TO HAVE CONFIDENT IDENTIFICATION, YOU ARE ALMOST 
CERTAINLY GOING TO HAVE TO VISIT AND WORK WITH SOMEONE WHO KNOWS WHAT 
THEY ARE TALKING ABOUT.

THE MOST EXTENSIVE SPECIES LEVEL GUIDE TO BODO IS THAT OF ZHUKOV - IN 
RUSSIAN.  IT IS NON CRITICAL, BUT FAIRLY COMPREHENSIVE.

PROTOZOAN TAXONOMY IS A COMPLEX BUSINESS, AND IF TO BE USED MEANINGFULLY 
SHOULD NOT BE UNDERESTIMATED.

FINALLY, I CAN PROVIDE A VIDEO TAPE SHOWING SOME OF THE MOST COMMON GENERA.
