A second bow-riding Harbour Porpoise was detected in the Oosterschelde, Zeeland (Delta area), distinctly different from the animal in Grevelingen, but with a very similar behaviour. A characteristic spot on the flanks is described to facilitate individual identification during future sightings. As with the Grevelingen porpoise in the first months of bowriding, this new animal is completely intact, with no visible scars. The close approaches to the sailing vessel it was reported from suggest that scars are likely to develop that can further characterize this individual.
