Jellyfish or jellies are softbodied free-swimming aquatic animals with a gelatinous umbrella-shaped bell and trailing tentacles.Between these layers is a gelatinous material called mesoglea, which makes up most of their bodies. Jellyfish and comb jellies are 95 percent water and so, rightly, mesoglea is mostly water! Some jellyfish have millions of very small stinging cells in their tentacles called nematocysts. These cells are used to capture food by injecting toxin into the prey. When we are stung it hurts because the toxin goes through our skin!

Info: Should you fear the Jellyfish?LINK FOR MORE INFORMATION ^^
As jellyfish squirt water from their mouths they are propelled forward. Tentacles hang down from the smooth baglike body and sting their prey. Jellyfish stings can be painful to humans and sometimes very dangerous. But jellyfish don't purposely attack humans. Most stings occur when people accidentally touch a jellyfish, but if the sting is from a dangerous species, it can be deadly. Jellyfish digest their food very quickly. They wouldn't be able to float if they had to carry a large, undigested meal around.

Most species of jellyfish live for less than one year. Some smaller species may only live for a few days. Jellyfish live in the sea and are found in all oceans. Some jellyfish live in fresh water. Jellyfish look a little like umbrellas. Jellyfish can be large and brightly colored. They can often be transparent (see-through) or translucent (semi-translucent). Some can be very hard to see, nearly invisible to the human eye. Although the word is mentioned in their name, jellyfish are not fish. A group of jellyfish is called a ‘bloom’, ‘swarm’ or ‘smack’. Large blooms can feature over 100000 jellyfish. Jellyfish don’t have brains. Jellyfish use their tentacles to sting. Most are harmless to humans but stings from some species, such as the box jellyfish, can be very painful and sometimes kill. Box jellyfish are almost transparent (see-through).Jellyfish eat plankton. Some sea turtles eat jellyfish.
