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!

How much does a jellyfish eat in a day?
Jellyfish don't have a set number of times they eat per day, like humans. They drift and graze on food as often as they can get it, and so the amount of food they may eat from day to day can vary greatly.
There are a number of things that happen to jellyfish on land. The most common ones include conduction and convection. This is what causes it to appear like jelly that is shapeless while on land.
How do jellyfish obtain nutrients for all life functions?
jellyfish catch small fish with their tentacles. The tentacles are covered in nematocysts (small sacs) that are filled with venom. when the organism they caught is killed (or even just stunned) they use their tentacles to bring their catch to their 'mouth' (in the center of their bell) where they digest it. jelly fish only have a simple digestive tract, so they do everything in it. the prey enters, they digest it, then basically spit out the leftovers that they don't have a use for.
What is the relationship between a nomeous fish and man-o war jellyfish?
mutualism is what symbiotic relationship theese two sea creatures have
Why are blue bottle jellyfish dangerous?
They are dangerous because of the fact that their venom can cause an unusual and dramatic syndrome that is commonly known as irukandji syndrome and can possibly lead to death. Then, as if this does not make it bad enough, the irukandji is very small in size, 2 cm to be exact and have for retractable tentacles that add to the danger. You don't see them coming and they could possibly kill you if not treated properly.
they sting worse than other jellyfishes also they are called box jellyfishes ?

What predators eat irukandji jellyfish?
The Irukandji jellyfish eats small fish and shrimp. The jellyfish will also eat other jellyfish and any other marine animals that it can catch and kill.
What continent and country are jellyfish found in?
Jellies are found in every ocean, from the surface to the deep sea.
Is a Man of War jellyfish bigger than a man?
On average, the height of a jelly fish ranges from one millimeter in bell height and diameter to nearly 2 metres (6.6 ft) in bell height and diameter; the tentacles and mouth parts usually extend beyond this bell dimension.
The Average Length of an Adult whale ranges from 35-50 ft.
The whale is way bigger than a jelly fish.
Yes, most beagles love peanut butter and it is fine for them to have as a treat.
How do jellyfish survive in the ocean?
Well the jelly is over 98% sea water, so it is almost at an equal salinity as the water surrounding it. It is designed to move with the water, so the waves will not tear it apart, and it uses very little energy as it mainly flows with the ocean currents, so it needs very little to eat.
How big is the blue bottle jellyfish?
The float or body of the blue bottle measures between 3 to 15 cms. The tentacles can range in length from 15 cms up to 10 metres!.
Where do most rainbow jellyfish live?
Crystal jellyfish live offshore and near shore in the sea. They will spend the better part of their lives in their plankton.
Who is the enemy of a jellyfish?
most squids and some octopus have the enemies of a blue whale or killer whale killer whale would also eat a jellyfish if their hungry enough, sometimes they would even squeeze the jelly from a jellyfish. Sometimes the killer whale would win, other times the jellyfish would win the battle. Go jellyfish!
Yes, there tentacles when attached to opillio crab pods, the "spray" can sting your eyes very badly and you must wear rubber gloves because they are sticky and slimy in order to remove them from the crab pods.
Whats the size of a moon jellyfish?
Sun jellies can have a diameter up to eight feet, though many range smaller. I have seen very large ones before when there was a boom in jellyfish populations in the Puget Sound area when I was visiting there a few years ago. I did not go swimming that year. ;)
Can a jellyfish kill an electric eel?
Sorry, they are just not electric. While jellyfish do sting, this has nothing to do with electricity. Jellyfish have specialized cells on their tentacles called Cnidocytes. These cells have "triggers" that, when activated by prey, discharge a thread that punctures and injects poison into the prey.
Do baby jellyfish hatch out of eggs?
No, it all happens when 2 jellyfish mate and they drop an egg and sperm on the ground and the egg and sperm grow into a sea fur. Then the sea fur grows in a wierd shape and it starts to shed. The shape of the shedding is a baby jellyfish polyp. It is kind of like hatching out of an egg, but not really.
Other species of jellyfish are among the most common and important jellyfish predators, some of which specialize in jellies. Other predators include tuna, shark, swordfish, sea turtles, and at least one species of Pacific salmon. Sea birds sometimes pick symbiotic crustaceans from the jellyfish bells near the sea's surface, inevitably feeding also on the jellyfish hosts of these amphipods or young crabs and shrimp.
What does a sea wasp look like?
There are many creatures on this earth that are quite deadly to humans. The deadliest of all, of course, being other humans. Perhaps, what poses the greatest threat to our lives are creatures we can't even see - microbes. These are the microorganisms we usually call germs or cooties, the ones that make us sick. By and large, disease-causing germs are responsible for the largest number of human deaths every year. But what we're talking about here are the venomous creatures; those whose bodies manufacture toxins that can be rubbed off, ingested (swallowed), or injected into another, causing severe illness or death. Just to name a few, there's the poison dart frogs of the Costa Rican jungles, stonefish, cone shells, the black mamba snake, and even a tiny octopus that lives in tropical waters. When creatures are rated for the "deadliness factor" there's a couple of measures that are taken into account:
1) How many people an ounce of the creature's venom can kill
2) How long it takes you to die from the venom after being bitten, stung, or stuck
In both cases the grand prize winner and world-record holder is the creature known as the sea wasp, or marine stinger. The venom from a single creature can kill up to 60 adults! Over 100 people have been killed by the stings from a Chironex fleckeri and many more have been stung, but lived. Get stung badly enough by one and you could be dead within four minutes. The name sea wasp is misleading because the creature isn't actually a wasp or insect at all. It is a jellyfish. The "bell" of this box jelly can get as big as a basketball with up to 60 tentacles hanging down as long as 15 feet, which is pretty good sized jelly. Not as big as the world-record jellyfish, though.
