Jellyfish

The life cycle of a jellyfish is planula - polyp - polyp budding - ephyra - medusa.

No, jellyfish do not have cell walls. They belong to a group of animals called cnidarians, which have cells surrounded by a cell membrane but no cell wall like plants do. Jellyfish have a simple body structure with a jelly-like substance called mesoglea between their outer and inner cell layers.

1. nematocysts-stinging cells located inside the cnidoblast and is used for defense and feeding on prey.
2. carnivores- passive drifters that eat dead or living prey
3. made of 95% water
4. Radial symmetry
5. never stop growing!

They both use there tentacles to capture there prey and the mouth is near the center of the body

The amount that a thimble will hold -- about 1/2 teaspoon. It is not used for an exact measure. It's just a way to saying "very little".

It is a Jellyfish which has very, very long stinging tentacles.

1988 thru 1998 look basicly the same.

No. they won't do you that favour.

I mean to believe that the tentacles that stung you can't sting you a second time, though. After stinging, they're out of ammunition.

It will die.

== == There are more than 200 different species of Jellyfish. Jellyfish are invertebrates and they come in different shapes and sizes. The longest jellyfish is the Arctic lion's mane whose tentacles may stretch up to 100 feet in length. Jellyfish can be found in all the world's oceans and even in freshwater. Jellyfish are 95% water. They have no heart, brain, blood, or gills. The body of the Jellyfish is called a bell. What they do have is a mouth, tentacles, and arms around their mouth. They use their arms around their mouth to help sense and find food that ends up inside their mouth. Jellyfish can sense smells and tastes using chemoreceptors. Also they can remain balanced in the water. Jellyfish eat small animals called zooplankton. An adult female jellyfish produces eggs and holds them around her mouth. The male jellyfish releases sperms into the water that the female jellyfish collects with her tentacles.Then the female jellyfish fertilizes her eggs.The mother jellyfish carries them around until she finds a hard place like a rock or a shell to put them. When the jellyfish hatch they are called ephyrae. Jellyfish have only a few predators because of the fact that they can sting. A few of their predators are the Banner fish which are not bothered by their tentacles. Arrow Crabs gobble them up in one bite. Turtles, certain fish and snails nibble on the jellyfish's tentacles. Also scientists research jellyfish. There are different kind of jellyfish like the moon jelly that are bioluminescent and give out light in the dark. There are 3 main reasons that the jellyfish uses bioluminescence. The 3 reasons are that they use it to mate and give out signals to their mate.The other reason that they use it to protect themselves from predators and to eat. == ==

The Jellyfish season in Chesapeake Bay varies on the species. Some species are seen from May to October, and others are seen November to March.

Jellyfish reproduce at a rapid rate and are almost to the point of over population. Because of their rapid reproduction and from being eaten or killed, it is difficult to know their population numbers.

It seems as if there is some type of algae growing in your pool. You will need to add more chlorine and shock the water to help kill it.

Most of the sewers in central London were built in Victorian times so they are at least 100 years old.

Prey

Man o' War was one of the greatest race horses of all time. He was sired by Fair Play, out of the mare Mahubah. Some of his famous offspring include the 1929 Kentucky Derby winner, Clyde Van Dusen, and the 1937 Triple Crown winner, War Admiral. He was also the grandsire of Seabiscuit, who beat War Admiral in a famous match race in 1938.

they communicate by sending out a series of bubbles a bit like how we used to do the clicky thing in world war one hope i helped ;-)

The jellyfish sting burned like lightning.

If I'm not mistaken, you need an anti-venom of some sort...I would get to a hospital & not take any chances. I think they can ;be lethal....

Depends where you live, but I don't think they would.

Many types of marine life possess what is known as bioluminescence. It is as yet unclear what stimulates certain animals to exhibit this trait.See link:

The most common causes include complications of the progressive, degenerative spinal disease called spondylosis, as well as traumatic injury to the cervical spine, such as fractures or dislocations.

Going with the flow and taking you whever life takes you. As the current takes the jellyfish wherever the current goes

All living organisms have a very complex chemistry.

great question, yes a portuguese man-of-war can kill a jellyfish.

Sea slugs, sea turtles, sea birds, and some sharks.
