In regards to us right now, animals listed on the Injurious species list of the Lacey Act cannot be imported into the US, or transported across state lines (I believe the latter part of that is being disputed in court because the language of the statute claims that animals can't be shipped from The contiguous states to Hawaii, Alaska, or other US Territory but does not directly mention transportation between the lower 48). Nobody is directly taking snakes away from their owners in relation to the Lacey Act. Meant to be a means of controlling invasive species, this is more of an effort to cripple the market. Some effected species include.
Burms
Retics
Green Anaconda
Yellow Anaconda
Beni Anaconda
DeSchauensee’s Anaconda
Northern African Rock Python
Southern African Rock Python
