To my knowledge they are not endangered but close to being there and are illegal to import to Canada and most likely the US. I think this came into effect about 3 years ago. The one I own was purchased legit over 3 years ago and the original owner tried to get another one but couldn't. After a while they were showing up from private sales, most likely people smuggled them in.
There is no one I've heard of that has successfully bread them in North America.
