The first records of sea star wasting disease in Crossaster papposus in Europe.


ABSTRACT: Sea star wasting disease (SSWD) refers to a suite of gross pathological signs observed in Asteroidea species. It presents to varying degrees as abnormal posture, epidermal ulceration, arm autotomy and eversion of viscera. We report observations of SSWD in the sunstar Crossaster papposus, the first observations of its kind in Europe. While the exact cause of SSWD remains unknown, studies have proposed pathogenic and environmental-stress pathways for disease outbreaks. Although the present observations do not support a precise aetiology, the presence of SSWD in a keystone predator may have wide reaching ecological and management implications.
