Hannibal Gaddafi, the fourth son of Col Gaddafi commissioned a vessel with its own shark tank after becoming frustrated at being unable to charter cruise ships at short notice.The vessel – the Phoenicia, was to have entertained up to 3,500 guests with elaborate gilt-edged architectural flourishes, a 120-tonne chamber filled with seawater for two sand tiger sharks, two white sharks and two blacktip reef sharks. Flanked with marble pillars, gold-framed mirrors and giant statues, the shark tank was to be a unique centrepiece for his guests.After the 36 year-old fled to Algeria and the uprising felled the Gaddafi regime, the contract for the playboy cruise liner was terminated and the vessel was put on sale.
