By-the-Wind Sailors

A gale force south-westerly was blowing so I headed for Hive Beach, Burton Bradstock on the Jurassic coast to do some wave-watching. The sea was huge and grey topped by white manes. A deep roaring sound filled the air as waves broke across the shingle. Curds of foam were blowing across the beach like enormous snowflakes.

I walked head down into the wind scanning the strandline. What looked like a piece of clear cellophane caught my eye. On closer inspection I saw a beautiful whorled pattern like a spider’s web and realised it was a tiny By-the-Wind Sailor jellyfish (Vellela) only about 1cm across. It was transparent and delicate, but marked with a concentric pattern and topped by a tiny translucent sail.

I then noticed that there were hundreds of these tiny creatures all over the beach. Some were a deep sapphire blue and up to about 8cm long whereas others were completely transparent. All were whorled like finger prints and delicate as glass. They were scattered all along the strandline like miniature shipwrecked yachts. The tiny tentacles on their undersides weren’t apparent, but, when I picked one up it left inky blue residue on the palm of my hand.

Like exquisite solar panels, the tiny medusa convert sunlight to energy, their small sails align with the direction of the prevailing winds and they are carried helplessly along, often to be wrecked in their thousands on the west coast of America. It is unusual to see them in Dorset. Storm Desmond has caused the biggest influx of these marine creatures in a decade.

I’ve never seen these beautiful little crafts before and it was both exciting and sad to see so many stranded on the shore, left high and dry by the rough seas.
