Scogli

These are some of the "scogli" along the local coastline. I looked the word up, since I've always been at a loss to translate it. I found the following definitions: 1) cliff - which I don't think applies in this case, there's no sort of precipice to fall over here; 2) rock - which I don't like either as it seems just a wee bit too general!; and 3) reef - is this a reef? Maybe it is. Are there any geologists out there who can help me on this one?
