Southern (California) Alligator Lizard

Question

Lizard   Hi Donna,

I live in San Francisco Bay Area and we found this lizard in our backyard yesterday.  We think it is a California Alligator Lizard after doing some research and identifying photos online.  My kids would like to keep it as pet and I pretty much know what type of habitat I will need to set up after reading other posts but I need to know how large/long will this type of lizard fully grown to so I can prepare a big enough terrarium for it.  Right now it is about 8 inches long total length.  I have attached an image of it so please also tell me if this is the correct species.  

Thank you very much for your help.
Amy

Answer
Hi, Amy,
That's a beautiful lizard.  It is an alligator lizard, though I am not an expert, so can't be certain of which species.  I do recommend finding out whether it is legal to collect and keep this lizard where you live, as California does have strict reptile laws.

If it is legal, then you may keep it, but wild-caught animals do have some challenges when it comes to captive care.  First, the animal will have to be examined by a veterinarian, and a fecal sample tested for internal parasites.  All wild animals carry parasites, and these can build to lethal levels in a captive environment, due to reinfection.  So, to survive in captivity, a wild reptile must be rid of its parasites.

Acclimation is easy for some individuals, and more difficult for others...if the lizard refuses to eat in your care, you may wind up needing to release it anyhow, or it will die.  A large enclosure with a naturalistic environment may aid this process.

Correct temperatures, humidity, and hiding places are crucial.  UVB light is also needed for this species.

If all of the above sounds like more expense than anticipated, then consider releasing this lizard where you found it, and purchasing a captive-bred leopard gecko from a reputable breeder, instead.  A leopard gecko is a much better choice for a first pet reptile, and it will come already well-adapted to captivity and free of parasites.  Most leopard geckos are docile, and can be tamed and handled.  Always acquire a captive-bred reptile, if possible--wild-caught animals are best left to folks who have plenty of experience, and should be used to establish captive breeding programs.
