I have to laugh every time I read about the Snake "Black Market."

Who is going to raise up a collection of snakes, breed them, incubate them, and then look for buyers on a "Black Market?"
Where are they going to purchase their feeders and supplies, and what Vet are they going to take their illegal animals to when they need medical attention?

If one customer gets caught, and turns in the breeder in exchange for a plea bargain, or no charges to themselves, the authorities will have probable cause to investigate, and make a raid on the breeder.
If you have 20 animals in your collection, that is 20 separate State and Federal felony charges of possession, with the intent to breed and sell, plus the initial sale charge that started it all.

The animals will be euthanized, while snake racks, incubators, and other supplies will be taken and charged as paraphernalia.

I would say if you don't currently run a Marijuana grow house, Meth Lab, Black Market Adoption Agency, or good ole' fashion Whore House, you are probably not going to run a "Black Market" snake breeding facility, as it will probably carry similar consequences.
