The unusual sighting comes after an aerial photograph appeared to show a giant crab that was at least 50ft-wide lurking in shallow water in England. The incredible image, shared online in October, could soon have visitors flocking to the seaside town of Whistable, in Kent, in the hope of catching Britain's biggest crab. While some insist it is proof of 'Crabzilla', others argue that the shadowy figure is nothing more than an unusually-shaped sandbank - or is simply a playful hoax.
