The water is fairly brackish and weakly tidal, and the landscpe is karstic limestone.I haven’t yet tested the strength of their stingers.

They may even be a little tidal, if there is much of a tide here.

If you factor together a) the distance from the c, b) the amount of water movement (communication) with the sea, and c) the freshwater influx from ground water, you’ll get some outcome as to how saline the water is. I imagine this is essentially salt water.
