Jellyfish is the beauty of the sea. The current of the water and the wind is what takes it from one location to the next. They have spent most of their life, floating around for over 200 million years. These jellyfish are 4 inches tall and are the perfect paperweight for the home office. They glow in the dark and represent the Bio-luminescence of jellyfish. Blue-pink Moon Jellies are the most common jellyfish in the world.
