The tentacle on closely holds these game, retracts,with the umbrella shape body under polyp Holding, each polyp all cansecrete the enzyme, rapidly game in vivo protein decomposition.Because of the jellyfish breathing apparatus and the circulatorysystem, only have the primitive alimentary organs, therefore capturefood inCoelenteron in digests the absorption immediately. In burning hotsummer, when we when seashore sea bathing swimming, sometimes willsuddenly feel bodily the front chest, back or a four limbs stabbingpain, some like the feeling which is brushed by the leather whip, thatalso was the jellyfish unseemly behavior is puncturing the person.But, the general broken jellyfish punctures, only will feel 炙 thepain and appears inflamed, so long as spreads wipes the niterinflammation medicine or the edible vinegar, several days namely havebeen able to lessen the swollen area stop pain.

Why then on the jellyfish tentacle stinging cell doesn'tinjure the small herd fish? This is because small herd fish motionnimble, can ingeniously avoid the poisonous silk, is not easy toreceive the injury, only is accidentally also has carelessly diesunder the poisonous silk. The jellyfish and the small herd fishparagenesis same place, mutually for uses, jellyfish "protection"small herd fish, but the small herd fish swallowed the xiaosheng whichon the jellyfish body perched.The overwhelming power but the fatal jellyfish also has the naturalenemy, one kind of sea turtle may in the jellyfish community the freeshuttle, easily pulls apart them with the mouth to touch, enables itonly about to tumble, finally loses the resistance, becomes the seaturtle "the fine food".On the jellyfish tentacle middle thin handle has a pellet, insideslightly has a grain to listen to the stone, this is the jellyfish"the ear". The inferior sound wave impact produces which by the oceanwaves and the air friction listens to the stone, is stimulating theperiphery nerve receptor before, makes the jellyfish to approach thefor several hours in the storm to be able to obtain the information,thereupon, they resembled have received life your son, completelyvanished all of a sudden from the sea level. The scientists oncesimulated the jellyfish the sound wave transmission organ to performthe experiment, finally discovered could before 15 hours measured knewthe sea storm the news.The jellyfish although is low and so on the coelenterate, actuallythree generations under the same roof, makes one envy.

Jellyfish are members of the phylum Cnidaria. Members of this structurally simple marine group possess one of two body forms. Sea anemones, sea whips, corals and hydroids are polyps growing attached to rocks or other hard surfaces of the sea. Jellyfish and the Portuguese man-of- war are free-swimming medusae. Both body forms display radial symmetry with body parts radiating from a central axis. This symmetry allows jellyfish to respond to food or danger from any direction.
