Class Scyphozoa?

I photographed this about two weeks ago at a depth of sixty feet, a mile away from Boca Raton Inlet, Palm Beach County, Southeast Florida. Pretty cool looking, I am guessing Class Scyphozoa, but beyond that I haven't got a clue.

Nice shot whatever it is.

Super picture. Class Hydrozoa. Two tentacle hydromedusa Stomotoca pterophylla.

Thank You LeslieH. I did a google search, for Stomotoca pterophylla, and found this site http://www.checklist.org.br/getpdf?NGD001-07. So maybe Stomotoca atra.

Could be. I found another paper that lists S. atra for the Mexican caribbean. The name S. pterophylla came from the Humann & DeLoach guide to inverts of the Caribbean. With a little more searching I found that S. pterophylla was transferred into the genus Larsonia - that's why it isn't listed in the paper you linked.
