Random Research

I am still trying to determine what I want to do with my Grad Project. I kind of narrowed down the list, but not really. Right now I'm thinking that I might want to do: Books turned into movies, animal intelligence, swimming, marine animals, and a few others. I want to do something within one of these topics, but I can't find any reliable sources on the internet on most of them, because the areas I would like to look at are up to interpretation. Making it extremely difficult not only to do research, but to also to think of some kind of action I could do within one of these areas.
