Collected: About 500 m offshore of Assateague Island, VA in early June, 2006, just above the bottom using an epibenthic sled with a 365 µm mesh.
Notes: Note the lateral buds of medusae at the aboral end of the manubrium, which are not found on many local hydromedusae. We have rarely caught Rathkea in our collections off of Assateague, VA. It is more common further north, typically further offshore.
Collected by: Bill Johnson, Goucher College.
