Jellyfish

A portuguese man-of-war's head is filled with carbon dioxide which makes the man-of-war very light. Their weight is probably around a pound, though.

• Kingdom- Animalia
• Phylum- Cnidaria
• Class- Cubazoa
• Order- Cubomedusae
• Genus- Chironex
• Species-Fleckeri

An adult swimming cnidarian is called a medusa.

A portuguese man of war can deliver a powerful, pain sting that are very very painful to humans, but not death. However, if the portuguese man of war stung you enough times, you could die though. A dead portuguese man of war found on land could still sting you.

--------

There have only been four recorded deaths due to a Portuguese man of war. Three along the US southeast coast, and one in Italy. Anaphylactic shock was implicated in most of those deaths, and out of millions of physalia stings, the death rate is relatively low.

The jellyfish sting is made up of many individual harpoons the number of which varies with species. These harpoons are loaded with complex proteins which again vary with species. The harpoons are fired on contact, this is an automatic response. The jellyfish is essentially a hunter and uses its stings as an offensive weapon. The harpoons are fired at a supersonic speed and after fixing themselves into their prey will explode releasing their toxic proteins these explosions can carry on for hours after the initial attack. The toxic qualities regarding humans range from harmless to the most poisonous substance in the animal kingdom, literally capable of killing a human in seconds. There is little research as to treatment and many "old wives tales exist" the benefits of which are unproven. In the case of the more toxic species there is no known cure or anti venom. The popular beaches of the Mediterranean are experiencing a rise in jellyfish attacks, some of which are extremely painful and cause long lasting lesions. Proprietary creams, although, not a cure can promote healing of the lesions and prevent secondary infections.

Box jellyfish (class Cubozoa) are cnidarian invertebratesdistinguished by their cube-shaped medusae. Box jellyfish most visibly differ from the Scyphozoan jellyfish in that they are rounded box shape, rather than domed or crown-shaped.

yes, you can but you can only eat certain parts properly prepared.

Lion's Mane Jellyfish are mostly found in northern areas of the Arctic, Atlantic and Pacific Oceans. It prefers to live in colder waters, and favours a home in a shallow, sheltered bay, never moving deeper than 20 metres under water.

some nasty stuff Depends on the jellyfish involved but they all use one of the three called

cnidocyte,cnidoblast or nematocyte.

This is a type of venomous cell unique to phylum cnidaria. ( Jellyfish,coral,sea anemones and hydrae) the toxin causes sodium and calcium ion transport abnormalities, disrupts cellular membranes, releases inflammatory mediators, and acts as a direct toxin on the myocardium, nervous tissue, hepatic tissue, and kidneys.

Specifically, the toxin may contain catecholamines, vasoactive amines (eg, histamine, serotonin), kinins, collagenases, hyaluronidases, proteases, phospholipases, fibrinolysins, dermatoneurotoxins, cardiotoxins, neurotoxins, nephrotoxins, myotoxins, and antigenic proteins.

In more simple terms. It's bad stuff and it hurts.

Translation: Qandil al-Bahr (قنديل البحر)

This refers to jellyfish both as a food item and the living animal.

Previously, there was the answer Halaam al-Asmaak (هلام الأسماك) which literally means "the jelly of the fishes", not the particular animal of the jellyfish.

You can buy a box jellyfish from sites such as The Marine Center. Before purchasing the fish, you need to make sure that you are going to be able to care for it properly.

Contrary to the concept of the movie Seven Pounds, Box jellyfish poison is a neurotoxin, and it is distributed to every part of the body, making organs unfit for transplant.

Scientists still don't know the oldest age of the turritopsis nutricula since this creature turns back into the polyp stage.

The phylum of the box jellyfish is Cnidaria. The kingdom for the box jellyfish is animalia and the class is Cubozoa.

Yes, jelly fish usuelly eat small bits of dead seaweed and it sings small animals then eats them

Many are predatory, and use their tentacles to sting and ensnare small fish as stated above, whereas others graze on plankton. The eutrophication of the oceans has led to huge increases in jellyfish numbers, due to agricultural runoff.

Jellyfish are strictly carnivorous. No bits of dead seaweed. And they don't sing to small animals and then eat them, grin.

many jellyfish, including the box jellyfish, are eaten by sea turtles. (some jellyfish eat one another). sea turtles are usually unaffected by even a sting as deadly as one from a box jellyfish. Of course like many animals, many die from habitat lose, nets, captivity, or being fished and eaten. There for, in some ways mankind is the largest predator of theirs.

Jellyfish mating is called spawning. This is where the female expels her eggs in to the sea and a male cast sperm over them

after mating planulae is released from the female which is like the baby eggs, and they drop to the ocean floor, they can lay there for many years, until the conditions are just right and they all bloom or "come out of their egg"

well it isn't impossible for for a human to do this because my friend has

i no kathryn

Well i think she was on the beach when she did it! XD x]

yeh<3 she did

jellyfish sting you and clams dont harm you at all:)!

simple: jellyfish phobia, that's the only name fore it

A jellyfish does not have a brain or centralized gathering of nerves. A jellyfish does have a neural net, which is a system of nerves spread out through the body of the animal, and helps the jellyfish maintain its sensory organs and respond to stimuli.

Jellyfish live in oceans and are not found in rivers.

Jellyfish do not have tongues. However, they do have special cells that allow them to smell and taste their food.

Coral and Jellyfish are classified together because share characteristic such as radically symmetrical, simple net nervous system, distinct larva stage. The classification is the phylum Cnidaria.
