Haha unfortunately I dont think we will ever see those guys in the pet trade, STUNNING things but so fragile. Apparently they drink by sucking water up through little channels in their legs and back etc and syphon it to there mouth. Awesome.
The name that comes to mind is regal horned lizards is what the shop was selling them as I think?There are different sub species. Some are very cheap but some are extremely expensive. The rarer ones are only seen on the continent generally. The ones over here sell for as low as 30 quid. They're currently on the trade lists so most shops should be able to get them in if you ask.
