[Coral-List] Gorgonian Sea Fan Identification

[Joseph Marlow]

Dear Coral Listers

I'm a MSc student studying the Aspergillosis disease in Gorgonian sea fans in the Cayman Islands. I'm having a lot of difficulty distinguishing between G. ventalina and G. flabellum, I know there is a difference in the branch structure but am unable to identify this difference underwater. I wander if anybody has any handy tips for aiding the identification of the two species?

Thanks and regards
