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 do jellyfish support their bodies?
Jellyfish have what is called a hydrostatic skeletal system. This means that it is not actually hard. It is more similar to a balloon filled with water. It allows the jellyfish to move in the water as well as allowing its body shape to change with the movement of the ocean and with the jellyfish's own movement without causing injury to the animal. This kind of flexibility is required for such a delicate animal to survive. It's really an amazing system. When the jellyfish contracts the muscles surrounding the pouch (its hydrostatic skeleton) it causes movement.
Jellyfish are not the only animals with this kind of skeleton. For example, earthworms also have a hydrostatic skeleton. That is why they can be long and skinny one moment, and short and fat the next.

Actually chief...an exoskeleton is any form of skeleton on the outside of the organism. this can be chitinous (sort of like that hard shell on crayfish or "bugs" i.e. arthropods), hydrostatic (which is closest to what you are describing i.e. slugs, worms, etc.) and several others. A n exoskeleton can also be combined with an endoskeleton in organisms like fish(scales) and turtles(shells). There are several other types also which i do not know enough about to comment.
So yes, jellyfish have hydrostatic exoskeltons
How do you get rid of a nettle sting?
Mulching, pre-emergent and post-emergent broadleaf weed killers, removal of rhizomes and rootstock, and solarization are ways to get rid of nettles. The perennial weeds in question belong to the Solanaceae and Urticaceae families. They spread by rhizomes underground and by seeds above-ground in compacted soils as well as in grounds benefiting from full sun, good drainage, and sufficient nutrients.
Are there box jellyfish or other dangerous jellyfish in the sea around the Seychelles?
"Box jellyfish" or "sea wasp" is also a common name for the notoriously dangerous Chironex fleckeri. Box jellyfish are among the most venomous creatures in the world. Each tentacle has about 500,000 cnidocytes, harpoon-shaped needles that inject venom into the victim. Stings from these species are extremely painful and often fatal to humans and prey animals. Their venom can kill a human in a minute.

Dogs like to sniff and mark their territory and most dogs are extremely clean and prefer a clean area to do their business on.

What is the difference between a jellyfish and shellfish?
There are alot of differences between these two marine creatures.
Just generally:
Turtles are a reptile that have the trunk of their bodies encased in a hard shell.
Jellyfish are umbrella looking and have soft gelatine-like (jelly) bodies. They have tentacles trailing from the bottom, which in some species can be toxic.
ADDED. Another difference: predator and prey. Turtles, or some species of them at least, eat jellyfish! This explains the distressing number of turtles dying having mistaken floating polythene bags for jellyfish.
