Jellyfish are among the strangest sea creatures because they are almost entirely made of jelly. They do not look like fish and they are not related to them at all. They protect themselves with a sting that is unpleasant and can sometimes be very dangerous. Jellyfish are shaped like an overturned bowl. The digestive system is under the bowl. The digestive tract ends in a tube that hangs down from the center and has a mouth at the lower end.
Tentacles, hanging from the edge of the bowl, gather food and are sometimes used for swimming. Between the tentacles are nerve centers and sense organs. The bowl of the jellyfish is made up of two thin layers of tissue with jelly-like material between them. If a jellyfish is removed from the water ii dries up very quickly because 98 percent of its body is water. Of course, if the jellyfish is quite small, being stung by one may not be too dangerous.
But when it comes to the big ones, that’s a different story. Experts report that jellyfish exist with a bowl of nearly 4 meters in diameter and with tentacles more than 30 meters long. When a jellyfish-like this “embraces” you, it may make it hard for you to breathe and even partially paralyze you. The Portuguese man-of-war, which is one of the largest jellyfish, can kill and eat a full-sized mackerel.
It can cause serious injury to human beings. There is a kind of jellyfish found off the coast of Australia called “the sea wasp”, which has been knowE IO cause death in many cases. What males the jellyfish dangerous are the tentacles. Some of them are barbed and pierce the body of their prey. The barbed cells are connected to poison glands which kill or paralyze the prey.
