I think it may be Panicum repens, torpedo grass, an invasive non-native in Florida.

Here is a link that might be useful: Panicum repens, torpedo grass

Might be Zoysia.

Thank you for your responses. I am familiar with both torpedo grass and zosyia. It is definitely not zoysia and I do not believe it is torpedo grass. There is quite a bit of torpedo grass here and it generally grows at the edges of fresh water. The leaves are larger, and it is not as thick as the grass in question. Here is another picture of the grass.

I wonder if Centipede grass is a possibility. One of the physical characteristics is that it can be prickly to walk on with bare feet.

take some to your COUNTY agricultural extension office.. for a full ID

or maybe the lawn forum... or the FL forum.. if there is one

It could be a strain of Seashore Paspalum.

I think Nel might be right. I did not initially think it was seashore paspalum because it seemed much too coarse but I just found an article that states there are roadside varieties that are much coarser than those used for lawns and golf courses. It is extremely salt tolerant which explains why I found it on the beach. It is also more shade tolerant and darker green than bermuda grass which also describes the grass I found. I wonder why it is not used more often for lawns.
