I bet they would be a handful on the end of a gig if they started whipping their tail around.Sounds like you can probably gig them, but who really knows these days. Coming from a multi generation Florida family, we always had gigs in garage for frogs and mullet. A ton of fun.

Iguana Land Rule #7: When in doubt double tap.We stayed in a state park in the keys and we were advised by a couple of campers to watch our kids. The one was over 4' and pretty much didn't give a rats butt about people. He was steeling food off picknick tables. He didn't care for a chunk of wood to his head though. I'll give him this much, I thought I had killed him but he just swam away in a creek and was back at the neighbors in an hour.
