You give it back to the sea like Linda @ Lime in the Coconut..., "Starfish, my fave find in the ocean, especially when they are still alive and you can throw them back in", she commented on a post of mine.
Or you pluck it like Sherry @ Country Wings in Phoenix..., "Here is one of the live star fishes on the rocks. I was determined to take one of these home. Yes Hunny Bunny plucked her right off the rock out of the sea, just for little ole me!"
Me? I'm on board with Linda, or might just leave it alone.
