A 'Sea Serpent' of Mullet

Last night as the sun went down and the full moon came over Seaford bay Sussex. I spotted thin blue line in the water half a mile out that was covered in hundreds of bemused seagulls and wondered if it might be the return of the legendary 'sea serpent' that is seen in the autumn in Lewes and which is a tightly packed group of the 10,000 or so Thin lipped mullet, that inhabit the river Ouse, heading out to sea to spawn. Sure enough this morning the first of them appeared at the Winterbourne stream outlet in Railway Land nature reserve Lewes! Have a look at my BBC Springwatch film via this link;
