Unusual Observation of the Alien Sea Urchin Diadema setosum (Leske, 1778) in the Aegean Sea: Recent and Recorded Occurrences



The Aegean Sea has been invaded by Indo-Pacific species via the Suez Canal. The needlespined urchin, Diadema setosum, was first reported in the Mediterranean in 2006 off southern Turkey. The present study presents its recent northernmost occurrence as well as previous recorded occurrences of Diadema setosum in the Mediterranean.
