Clification of a few animals!!?

Unanswerable question, in part. There are many species of starfish and tapeworms and several species of rat snakes. May I suggest that you get to your local library and do the research yourself in a new invention called a "book". A good one for this is the Fieldbook of Natural History by Palmer and Fowler. The first edition was written by E. Lawrence Palmer alone. It's fun browsing thru the book too.
