I've seen these lately in my cousin's yard in Palm Beach. Can't catch them, fast as hell. the second one runs on his back legs like a Basilisk. they're both green and both about a foot long. the top one is more brownish with a sail that runs down his back. he looks almost like one of those anoles with sails but way bigger. the other is green with almost black stripes on his back and his head is kinda triangle shaped. What are they?

They both look like they're in the same family as the baslisk, not sure wha their common name is though. Iguanidae would most likely be the family, species i'm not exactly sure but it probably ends in basiliscus. The 2nd one looks a lot more like a green baslisk than the first one, but i'm no expert.

They are a pair Basiliscus basiliscus you can't be more of a basilisk then that. Basiliscus plumifrons and Basiliscus vittatus are the most common imports so that is quite a rare find. Since they are introduced species and compete with natural species, you'd be doing an environmental service by removing them. They are quite healthy looking.

What type of basilisk this is is Basilicus vittatus, also known as the Mexican or striped basilisk, a very common basilisk in the pet trade for years, in fact thats why they are all over South Florida, they are either pets turned loose or escapees, Basiliscus basiliscus as one person stated they may be are usually darker brown and get very high sails on the back and tail like the green ones, what these 2 pictures are of is a male, top picture, and a female, bottom picure of B. vittatus

From the picture, it's hard to tell what the dorsal fin looks like, I went with Basilicus Basilicus, because he described a fin that goes down the back and that it didn't look like the basilisks that he was familiar with, which would have been vittatus or plumifrons, so I still think Basilicus Basilicus is most likely, we would need another pic of the male to verify.
