If I remember correctly, Gila Monsters are a protected species. Isn’t it against the law to own them?
From Wiki:
...protected by state law in Arizona.......
Conservation status
Gila monsters are listed as near threatened by the IUCN.[1] They are listed as “Apparently Secure” by NatureServe.[44]
In 1952, the Gila monster became the first venomous animal to be given legal protection.[45] They are now protected in all states of their distribution. International trade in the species is regulated under Appendix II of CITES.
Yes, I believe in Arizona it’s a crime to even touch them. They’re venomous and have a filthy mouth, but they’re very slow-moving. Anyone who gets bitten by one must have been pestering or threatening it. I have several that trundle across my driveway and thru the backyard. Along with the rattlers and other snakes, they help keep the rodents in check. I love having them around.
There’s a FB page for Gila Monster and Mexican Beaded Lizard owners.
