Jellyfish

It just stings if it is a minor jellyfish.

No. It may injure or paralyze a shark, especially if the shark gets too close to its tentacles.

It could depend on the species of shark and the length of tentacles. A portuguese man of war with any length range of tentacles of at least 50 ft could even kill a big great white shark.

Jellyfish tentacles contain stinging cells, which can cause minor irratation or even death to humans or creatures. They than use their tentacles to their food up to their mouths where it is than eaten.

This may happen because there was a storm the night before. This may also happen if the current changes during a very high tide.

Polymorphism or different phenotypes in a single species could be responsible for the diversity in the cnidarians evolutionary tree which happens to be extremely diverse and complex, ultimately increasing its chances of survival.

Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.

Unlikely. Anything's possible, but Jellies have roamed the seas for at least 500 million years, and possibly 700 million years or more.

Jellyfish are in the Phylum: Cnidaria

Cyanea capillata is the latin namefor lions mane jellyfish.

not at all

They live in sea. They are invertebrates. Invertebrates are animals with no backbone. They also have stinging cells.

Some species have 216 chromosomes!

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.

A jellyfish is an animal in the cnidarian phylum along with anemones and other creatures with nematocysts (stinging cells). Some are tiny and some can grow very large (i.e. the lion's mane jelly). All jellyfish have nematocysts, however some jellies possess very weak nematocysts meant for tiny prey like copopods. The stinging cells in these jellies are generally not felt by humans with the exception of sensitive skin. Cnidarians do not possess brains, but some have eye spots for sensing light.

The head or body of the jelly fish is called the bell.
The Bell.

I was stung by 3 jelly fish, first I applied vinigar but dident feel any releif from the pain, then I had a VERY HOT shower with gave immediate relief then i put mono floral honey (pure 100% honey) on 2 of the 3 stings. The 2 stings that I applied honey too were 80% gone with in an hour or applying the honey. The one sting I did NOT rub with NO honey was still sore and still had big red welts 72 hours later.

100% Honey works very good on jelly fish stings.

No; jellyfishes haven't a true skin, they have only a thin epidermis. they are only made up of two layers of cells and a layer of "jelly-like" substance called mesoglea in between.
Yes they do

some hours. no more than three or four hour.

Jellyfish refers to the medusoid stadium of animals belonging to different classes and orders of the Phylum Cnidaria.

Jellyfish do not actively control their body temperature, their body temperature is that of the water surrounding them. However, they can swim and could move to, or keep themselves in, a body of water where the temperature suites their needs.

A clam is more likely. Jellies have no bones.

Migration might be too strong of a term, but box jellies do demonstrate seasonal movement. During the spawning season (May - July) in Australia, box jellies congregate in the lower portions of freshwater rivers and mangrove channels. Their offspring then travel out to the coastal beaches during the wet season (Oct - Apr), where they grow to adult size and pose a serious threat to humans. Their life cycle completes when they travel back to the estuaries to sexually reproduce and then die.

There are dozens of box jelly species with varying life cycles and scientists are still largely unaware of the exact details, but the above description is generally true for the majority. Hibernation is not known to exist in these species.

Nope i don't think that would work as jelly fish are not pets and are used to salt water and huge spaces. It would be cruel to keep one in a fish bowl.

;-)

YES THEY CAN LIVE IN FISH BOWLS JUST POUR A BAG OF SALT IN THERE, TOSS THE JELLYFISH IN AN YOUR GOOD. DON'T LIE, A JELLYFISH COULD BE KEPT IN A FISH BOWL.
