Ok, do the appear randomly, since they all came one day. Or is there certain times, or beaches where the attack?

After a week in HH i got over a dozen ~5-7mm red itching marks, on my back mostly.
I have sea-bathed every day but the marks/bites all shoved up the same day. Except for a few on the legs a few days before.

I have heard previosly about sand fleas.
Could it be those? What is your experience?
