No. They can’t move. “Dead Men’s Fingers” are a form of coral that looks exactly like a hand with outstretched fingers.
They may even be colored like a hand, although they can also be orange or white. The “fingers” are a form of soft coral that do not have the ability of stony coral to form a hard limestone wall.
They are in most of the world’s oceans, and they can take some other very surprising shapes.
For instance, there are some in the cool waters of the North Atlantic that look like little mushrooms or tiny trees. Remember, they are not plants. They are living, breathing animals.
