I'm not entirely sure there's such a huge trade with importing animals anymore. Other than specific morphs and lines or hard to get species such as GTP's, QUOTE]
There is a huge import trade, GTPs are easy to get these days. With the exception of Corn snakes that are being bred in their hundreds of thousands yearly, most other herps fetch reasonable to extremely high prices on the black market, and whether they are being bred here or not, high prices usually means someone see's it as a good idea to make some money by importing them into the country. The busts that you see in the media, seem only to be a small portion of whats coming into the country.
