Yes, possibly true, but as most of us dive in a great many different places it is never safe to assume anything. I live in upstate NY but dive all over the Caribbean, as well as local. Sorry, but I had to ask.Since the original post was in the Western Canada section one would assume that the poster was talking about the West Coast of Canada.

Just saw something like those salp in your photo on a National Geographic special last evening at a friend's house. Great photo.
