Li Shiyang, holds a Saltwater Crocodile (Crocodylus porosus) in his home on the outskirts of Beijing. This juvenile is only two and half years old, but when fully grown can reach up to six metres, making it the largest reptile in the world. It's just one of five crocodilians he owns, along with two other large snakes. "There are twenty three crocodilian species in the world. We hope to collect all of them", he boasts. A Saltwater Crocodile can retail for up to 9000RMB (US$1500). In the wild, they can be found mainly in South East Asia and Northern Australia.
