Australian Marbled Catshark
Worth around £50,000, Feargal and Sharkey are the UK's only captive breeding pair of Australian Marbled Catshark, a rare species of shark.
However, the female (the aptly named Sharkey) was stolen by cunning thieves who broke into aquatics dealer Peter Newman's garage in Hampshire and netted his prized 2ft long, mottled brown shark.
