This is not a species we used to see in our waters ( we have never seen it before actually),they are all around in the Izmit bay last month, and increasing everyday. Could it be related to marine pollution or what? Some Experts say they have been carried by the overseas vessel\'s and released from the ballasts, and some says it is Just related to sea pollution...
