For all species of cephs, I'd recommend going to cephbase.com and on the left side of the screen click biogeography. I just found this link yesterday and am very impressed. you can search in the second drop down menu for Caribbean sea. http://www.cephbase.com/biogeo/spatialsrch.cfm For short!
Though it doesn't say anything about those that are common, and I wouldn't know either so I can't help you there. It gives you a place to start with though.
Thank you... I've been on Cephbase.You just have to look them all individually...Just hoping that someone would have a list or something that had names of species and where they are located. I've tried to research this but no luck.
Thank you for your help.
