Keeping exotics as pets is a touchy subject all in it's own. Most of the data that you will find will be trying to talk people out of owning exotics. Keep in mind that when you say "exotics" you are not only refering to reptiles, but bears, lions, tigers, etc. that anyone can get ahold of. Just as most of us in here support being able to keep them, we will at the same time try to deter someone away from keeping crocodilians, simply because of their requirements of upkeep and handling experience required. But if you ask the majority of us, we will provide info to help get you started and some pointers so that hopefully your animals will do well and prosper. Captive breeding is probably the biggest benefit. Education to the public and conservation of species is something else you might want to look at but conservation can file in with captive breeding if you are not careful. As much as I would love to sit in a pet store that sells exotics, and sell something to everyone who walks in the store with a fistful of cash, it wouldn't be responsible of me to do so. The reason for that would be that most of the people that come in with a fistful of cash to purchase the animal, shouldn't have it. Keeping exotics isn't exactly a right in my opinion. It is more of a privilege. I relate to that in this manner.....
When you are a kid, you get your parents permission to do things when you prove that you are responsible enough to do so. The more responsible you prove yourself, the more privileges you get. When you screw up and take wrongful advantage of those privileges, you get them taken away. While I feel that everyone has a right to own what they like. Not everyone deserves to. It is not always for the sake of the human, but for the sake of the animal. Many pet shop owners will disagree with this simply because, hey customers mean money.
" You want a nile croc? Hey I got one hell of a deal for you. How old are you by the way? 12? Hey no big deal, niles are like kittens. "
Ownership of exotics is sticky. Just make sure that most of your claims are supported by data. Check in with some herp socoieties, and so forth. I wouldn't go to any pet stores. Of course they feel that you exotics should be kept. It's money isn't it? I am not saying that every pet store/owner are this way. But quite a few of them are. Those quite a few are the ones that threaten our privilege the most.
I know this probably wasn't quite what you were looking for, but I hope it helps you in some way.
