Jellyfish sighting Buckland Gut

Over the course of two days,I observed over 20 jellyfish washed up on shore and in the marsh. The area is on a tidal creek- Pungoteague Creek that flows into the Chesapeake Bay. The jellyfish were on the sand beach and up in the marsh. Not sure how long they had been there, went out first on April 10 and then on April 11. Saw about the same number on both days, though realize I could have been seeing the same ones.
