Sinepuxent Bay, Great Egging Island

We were kayaking in very shallow water off Assateague Island National Seashore when we came across a single pink jellyfish near shore. We took a video and a photo with our phones. We aren't sure of ID. It was about 7-8 inches in diameter with 7 transparent lobes or scallops around its edge and a darker pink ring of depressions inside this. No clear gonads. The water was only about 8-10 inches deep off the coast of Great Egging Island in Sinepuxent Bay.
