Dear FaCrox, The presence of Necora puber in the Western basin is considered a natural dispersal but its appearance in other parts of the Mediterranean Sea had raised the question about its status. In Zenetos et al. 2010 (Annotated list of marine alien species in the Mediterranean with records of the worst invasive species) they consider N. puber as an alien species because "we believe that its presence in several areas of the Mediterranean is due to introductions, most likely related to its widespread food use rather than an entry through ballast waters. Only the specimens collected west of Malaga (Garcia Raso et al., 2010) could have entered the Mediterranean through the Strait of Gibraltar by their natural means of dispersion". I think we need to collect more data to decide if it is indeed an alien species to the Mediterranean Sea or not.Because of that I would also refer N. puber as a cryptogenic species. Ya'arit
