I checked into that in '03 when I was on Dean's list for couperi. I called F& W and had to speak to someone named Linda. I made the argument that couperi are not indigenous to our lovely state, so they should not require anything besides a hobbyist permit.
Upon talking to their "biologists" it was decided that keeping couperi in NJ would neccesitate an endangered spp permit which was $38 a year and included mandatory visits by the state to check on the animal's quarters.
Now this permit is not difficult to get! They were very helpful. However, Dean had a bad year last year, and I perosnally did not want strangers in my house telling me that I keep my snakes properly. Shoot, I already know that! I did get the paperwork, and it wasn't that bad!
However, you do need to keep them for reasons other than pets (research, education). This wasn't a prob for me as I'm a teacher.
Damn, with all this legit info, I should be an officer in the NJHS!
