i have also heart about shipping them dry...seems odd to me...anemones STINK when they are dead...i'd hate to crack open a box and take a wiff of that puppy...but if all these sites are shippping them dry there must be a reason for it....
When you ship anemones out of water there's 1. less water pollution from the anemone itself during shipment especially if it gets disturbed during transport. 2. Anything shipped in water is certain to get sloshed around a great deal during transport. Anemone without water shouldn't get sloshed around nearly as much as one riding waves in it's bag when it's box is getting driven around and carried.
Just a few thoughts
