Are there sharks in the Aegean Sea?

No, the sharks prefer Hawaii. But there are sea urchin at some of the beaches. They do not bite, but they are toxic and stepping on one is a rather unpleasant experience which might have consequences. Yet there is a slim chance to do so since, thanks to its high salinity, the water is crystal clear and the visibility is pretty good.
BTW, did you know that (as of December 17, 2018) there are only 5 fatal shark attacks in the whole world out of only 101 encounters, many of which were provoked by the human.
