Hi, I know how you feel when ppl think you're strange because biology and reptiles( especially crocodilians) are what you want to do with your life. But it is possible. I am attending Blackburn College right now doing just that. I work with our reptile collection on a daily basis. As for keeping crocodilians, I have just now considered it as a possibility. The only reason I have even thought about it is because I have access to a laboratory and the necessary equipment. This hobby is very intensive and can be difficult to actually perform. Bide your time and keep your eyes and ears open. Absorb all the info you can cram into your mind. One day you will have the opportunity to put it all to use.
