It all depends on what type of seaweed it is. The type of seaweed (ie colour, parts some have and others don't, size) determines where it can live without being harmed. For example, if the seaweed is strong, it can live in very rough, wavy areas. If it is not, it could live on a beach or a rock, close to the water.
