Often seen around this time and earlier in the summer. Seen with Herring Gull and other small birds.
Inhabit the area year round. Often feed on clams and starfish. About three species of gull are in the area.
Some Cnidarian ( I think) that was clear, about 3 inches long, and bioluminescent. I found it in a bay at Long Beach Island. also, I have a video, but I don't know how to upload it.
Spotted multiple consecutive years. When approached, went into trees, suggesting possible nest site.
