There are many unusual species of Reptiles , Amphibians and Invertebrates being held in private hands and imported by dealers , a lot of them being successfully bred . If anyone has a spare £2000 they could buy a Chinese Alligator from a dealer in Gloucester and get 1p change . I am not keen on the attention being given to breeding colour morphs of so many species though .
Assuming this is true (the person that told me doesn't seem like a liar), but I've heard of a private owner that is successfully keeping a Thorny Devil (or devils?) in Britain. I've forgotten all of the details, but I know that they have a picky diet.
