Many of these jellyfish littered Ocean Isle Beach, NC over the week-end. Storms and rough seas offshore pushed them into the breakers and beaches. This is the migrating season for them to head north. In the fall, they migrate southward. They are called "jellyballs" by local folks. From a pier or a boat, they look llike coconuts floating just beneath the water's surface. Our dogs wanted to check each one out as we walked the beach.
