This jaw-dropping £450m concept for a mega-yacht has been inspired by a shark.
The 501ft long and 112ft wide 'Prodigium' features fin-like structures and windows that echo the toothy grin of the marine predator.
The vessel, designed by Lazzarini Design Studio, is spread over six levels.
It also takes inspiration from roman architecture.
A spokesperson says: "Construction would take about 28 months in the bravest shipyard of the world."
