A COASTAL stroll became a walk on the wild side for visitors to a stretch of South Lakeland sands last week, following the appearance of a mysterious marine creature, reports Ruth Lythe.The creature, which was spotted by walkers at Fish Carling Point on Milnthorpe Sands, has had people puzzling over its identity over the past week.The animal, which has gained an orange hue as it decomposes, has been a source of mystery for sealife experts.Although experts from the Seawatch Foundation are not totally convinced about the creature's identity, the most likely solution to the mystery is that it is a bottlenose dolphin.However, whether the dolphin was alive or dead before it arrived at Morecambe Bay, is unclear. Seawatch is interested to hear of any sightings of dolphins alive or dead on Cumbria's shores.You can register your sightings at www.seawatchfoundation.org.uk or call 01865-717276.
