ID of Pelagic Invertebrate

[scubarob97]

Hoping someone can help me identify a pelagic invertebrate I saw at Marine Room in San Diego on 7/11. At first when I saw it, thought it was a salp but closer observation I realized I had no clue and never seen it before. Used 6omm so didn't get entire photo of it. It was long and stringy and skinny.
Here is the link to the photo of it. Any toughts on ID? Thanks in advance and happy diving everyone

Looking at my book, I believe that is a siphonophore - Apolemia uvaria.

I've seen that one a few times recently, it can get up to 50ft long or more.. I think Tracey has the id right, it's a siphonophore, same group as a portuguese man of war.
