Jellyfish

Depending on the species, the body contains between 95 and 98% water. Most of the umbrella mass is a gelatinous material - the jelly - called mesoglea which is surrounded by two layers of protective skin.

A jellyfish sting from a box jellyfish can kill a person in minutes if not treated. From other jellyfish, it might only sting. you can atually help it if you urinate on it.

Radial symmetry is how biologist describe a jellyfish's body plan. It means that the body parts radiate from a central axis.Jellyfish have body types that are dubbed coelenterate, which means they have a body that looks like a sac. They have no real bones or skeleton in their bodies.

probually around 6 ounces.

The mouse and jellyfish are being compared because, the mouse is less likely to decompose when the scientist try to fossilise it, but the jellyfish has the tenticles and when scientst are trying to cover it, it will most likely fall apart/decompose.

since they pray on fish eggs, their overpopulation is allowing numbers in fish in the Mediterranean and Australia to decrease at a huge rate.

because they aren't, put this on your paper

The spotted jelly, lagoon jelly, golden medusa, or Papuan jellyfish (Mastigias papua) is a species of jellyfish from the Indo-Pacific.

Jelly fish are not true fish, so are members of a different animal class than are true, bony fishes. Jelly fish bodies are supported (or not) by hydrostatic pressure as opposed to bony skeleton.

I once heard that Vinegar will calm it, so when i got stung in the face while surfing in Mexico, I used the mustard from the cooler box! Yes, it worked, calmed the sting and pain and slowly dissolved.

The exact population of all species of jellyfish is unknown. However, it is likely in the tens of millions for each genus of "true" jellyfish.

Jellyfishes are not electrical.

Four semicircular pouches that open from the sides of the stomach and are the sites of extracellular digestion

a blue bottle jellyfish can live for about a year both in the wild and captivity.

Yes. Off of Apacha Point in Agat, there are usually swarms of tiny little stinging jellyfish no bigger than the size of a dime. I think the current pushes them in and they get trapped in the lagoon area between the micro islands just offshore. They are always there when we go spearfishing in the area.

jellyfish have no bones, exoskeleton, or shell to protect or support them. The jellyfish is considered simple-bodied because, like its Cnidarian cousins, it has no head, brain, heart, eyes, or ears. Thus it is also lacking in the sensory systems that correspond to these organs.

The Crystal jellyfish lives in open waters

Jellyfish Come In August through September, but sometimes they can come a month early.

The lions mane jellyfish was first discovered in 1870 when there was one found washed up on the shore at Massachusetts Bay.
