Jellyfish
Found in every ocean, jellyfish are not technically "fish." Jellies have an umbrella like structure that allows them to float beautifully in the water. Watch out though, some of them sting!

jellyfish do not have ink, you are mistaking them for squid, which use an ink like liquid for defense against predators.
Are there jellyfish in the Indian Ocean?

What do sea nettle jellyfish eat?
They eat small fish, small crustaceans, and sometimes they eat other jellyfish. (only if they're really hungry).
Is the box jellyfish Australian?
Although the notoriously dangerous species of box jellyfish are largely restricted to the tropical Indo-Pacific, various species of box jellyfish can be found widely in tropical and subtropical oceans, including the Atlantic and east Pacific, with species as far north as California, the Mediterranean and Japan and as far south as South Africa and New Zealand.
What are the small brown jellyfish found in the Caribbean Sea by the US Virgin Islands?

Jellyfish can vary greatly in size and length. Some jellyfish are hardly millimetres across, but the longest one, the Arctic lion's mane jellyfish, has tentacles that can grow up to 100 feet in length.
What are the general characteristics of jellyfish?
Jellyfish are not actually fish, and have no blood, brain, bones, or respiratory system. They have no typical central nervous system, but have a network of nerves called a â??nerve net.â?? Jellyfish have an internal cavity that carries out the functions of both the mouth and the anus. Jellyfish are made up of more than 90% water. They usually live less than one year, some only living a few days. Jellyfish vary in size and can range from the size of a pinhead to larger than a human. They eat small fish, shrimp, small plants, and crabs. Large groups are called a â??bloomâ?? or a â??swarm,â?? and can be made up of over 100,000 jellyfish.
Can you touch the back of a jelly fish?
Not without squashing it. I'd suggest wearing shoes if you try this. NO is you stand on them and they sting you. you can die The jellyfish is made up of 94 to 98% water and would not withstand your weight placed upon it. See the related link fo more information.
When was the jellyfish first discovered?
Jellyfish have been in the world's oceans for at least 500 million years. Some species might have been around before that, some 700 million years ago. They are the oldest multi-organ animal to exist.
What do you do if stung by a jellyfish?
Jellyfish deliver stings from specialized cells called nematocysts, which remain "alive" -- or at least reactive -- long after the animal dies. These cells inject a variety of toxins, including neurotoxins, that induce intense pain and paralysis. Only a few species of jellyfish have nematocysts that are hardy enough to actually pierce human skin. This is important to know, because dealing with "unfired" cells is the first step. Note that there have been fatalities from stings, especially associated with anaphylaxis, so not exposing the rescuer is critical. (According to the medical dictionary, anaphylaxis is "a type of allergic reaction, in which the immune system responds to otherwise harmless substances from the environment, e.g., an allergic reaction.)
1. Tend to breathing, if this is an issue. Remember to protect the rescuer here. Be on the lookout for anaphylactic reactions. 2. If there is a chance the cells still remain on the skin, you need to remove them. The best way is to make a paste of baking soda and seawater, gently spreading that over the affected area, and gently scraping it off with a dull edge (like a butter knife). If not all the ingredients are available, do the best you can -- but try not to agitate untriggered cells. You can replace baking soda with talcum powder, mud, etc., or even skip it if you can't find any. DO NOT USE FRESH WATER! THIS TRIGGERS THE CELLS. Do not scrub the affected area (with sand or anything else), as this triggers unfired cells. 3. If you have Alcohol (EToH or Methanol), pour it liberally over the affected site. This seems to numb remaining cells.
4. If caught within the first hour or two of contact, you can try to denature the proteinic toxins by applying a hot compress to the affected area for 10-15 minutes. BE CAREFUL NOT TO BURN THE PATIENT. But make the compress as hot as the person can comfortably and safely handle. 5. Apply cold compresses to dull the pain, although this will not really remove it. 6. In more serious cases, systemic painkillers may be called for. I've never had topical painkillers work at all, as the toxins seem to be antagonistic to Benzocaine and the like, but it probably wouldn't hurt if applied at the end of all the procedures.
I have heard of urinating on the affected area. But I've never had this work for me. Actually, urine is more than likely just another way of accidentally triggering unfired cells. Urine contains small amounts of ammonia, which supposedly neutralizes the agents. It can be tried in an emergency.
How does the moon jellyfish protect itself?
Jellyfish have cells called cnidocytes, which contain nematocysts, and located on their tentacles and on their manubrium. Whenever a predator comes in contact with cnidocytes, hundreds to thousands of cnidae (filaments of the nematocysts) are ejected in the predator's direction. Nematocysts' cnidae inoculate a poisonous or allergenic mixture into the predator's body.
During the Revolutionary War, food that soldiers ate was very bland. They usually had a steady diet, as opposed to the British who didn't receive as much food because it's much harder to supply an army that is 3,000 miles away, across an ocean. The diet of the soldiers included rice, beef or pork, peas/beans/another vegetable, Indian meal, spruce beer or cider, salted fish, molasses, bread or flour, and also vinegar. Rations were given out by either daily or weekly amounts. Closer to the end of the war, rations could run very low, and they did. The soldiers usually survived on "firecakes" - a mixture of water and flour cooked over the fire.
What are facts about a purple striped jellyfish?
Jellyfish fact: Jellyfish has been around for more than 650 million years which means that they outdate the dinosaurs and the sharks.
Jellyfish fact: Different species of jellyfish can be found in all the worlds' ocean. Jellyfish can even be found in freshwater.
Jellyfish fact: A species of jellyfish, the Box jellyfish (sea wasp) kills more people than any other marine creature.
Jellyfish fact: The worlds largest known jellyfish can reach a diameter of 2.5 m/ 8ft and their tentacles can grow to be half the length of a football field.
Jellyfish fact: Jellyfishes uses jet propulsion to make their way through to oceans of the world. Some jellyfish is avid swimmers while other mostly drifts with the currents.
Jellyfish fact: Some species of jellyfish contains a lot of protein and is thought to be able to play a large role in ending hunger and malnutrition in poor areas around the world.
Jellyfish fact: Jellyfish is able to reproduce both sexually and asexually during different parts of their life cycles.
Well there are over 1 million types of jellyfish but only 70 bare venomous to human beings. Um They all have 24 eyes that give them 360' Vision. The sting is a box jellies greatest offence- it paralyzes its prey the digests it into its stomach. And there you have some jellyfish facts!
How do jellyfish defend themselves against predators?
To capture food, jellies have a net of tentacles that contain poisonous, stinging cells called nematocysts. They use their tentacles like harpoons. When you brush up against them they shoot them out and inject the poison . When the tentacles brush against prey (or,say, a person's leg), thousands of tiny stinging cells explode, launching barbed stingers and poison into the victim.
There are primarily two parts to a jellyfish- the bell and stingers/tentacles.
(I think you know which one stings you)
They insert this little thing called a Cnidocyte inside your skin... or at least that's how I think it works.
The box jellyfish has rudimentary light sensors, but no jellyfish has eyes.
