What reptiles are legal in Illinois?

it is wrong because the petland by me has anacondas all the time. and i know many people with iguanas monitors snapping turtles etc. alligators and caimans however are illegal. this may be a list of what is baned in every city in the state kinda like chicagos hand gun law. i am not sure though. o and almost every pet store sells iguanas not to mention that is the lizard that people buy the most with false information.
