Further spread of the venomous jellyfish Rhopilema nomadica Galil, Spannier & Ferguson, 1990 (Rhizostomeae, Rhizostomatidae) in the western Mediterranean
The present paper documents the further spread of the venomous scyphomedusa Rhopilema nomadica Galil, Spannier & Ferguson, 1990, which first appeared in the Mediterranean off the Israeli coast in the mid-1970s. This report provides the northernmost and westernmost record of the species in the Mediterranean—from the eastern coast of the Italian island of Sardinia—based on a new record of the species within the Sicily Channel (Aegadian Islands) and provides evidence of its further establishment within Tunisian coastal waters. Key words: non-indigenous, scyphomedusa, new records, spread
