Popoise in river.

On March 10th 2008 the Medway Messenger reported that:

'Medway could have its own answer to Jaws - A creature with a shark-like fin, has been spotted swimming up and down the River Medway and is thought to be chasing shoals of fish. But the fin actually belongs to a Harbour Porpoise and not a Great White Shark. One resident described the marine mammal spinning in the water, while others said it looked like it was playing. The Harbour Porpoise is one of the smallest marine mammals and is commonly seen alone in shallow waters or estuaries. Some have even been spotted hundreds of miles from the sea.'
