But you be not afraid to look at jellyfishes. Actually they are very beautiful. Fancy small lamps, chandeliers, saucers and umbrellas with feelers, and all this translucent, ephemeral, often painted by the most delicate blue, lilac, brown and pink paints. Their slow graceful dances in water bewitch.

Live in the Mediterranean Sea and a fizaliya - surprising creations which main area is in warmer southern seas. Frankly speaking, the fizaliya is not absolutely a jellyfish. It is a colony from several hundred jellyfishes and polyps, each of which carries out any function. One of them get food, others digest it, the third protect a colony from enemies.
