Jellyfish or jellies for short are sea dwelling creatures and there are over 1500 species of jellyfish in the waters on earth, just as there are many fish in there see there are also many jellyfishes in the sea. These marine creatures can be found as close at the surface of the water to as far away as the bottom of the deep blue sea. Jellyfish also vary greatly in size ranging from as small as an adults pinkie finger fingernail up to the size of a washing machine or two. Jellyfish are usually transparent or opaque in color but there are some species which defy this law and are in beautiful enchanting colors such as purple, yellow and even orange.

Jellyfish do not have spines and their bodies are oxygenated by the process of diffusion because they have no respiratory system. Most jellyfish are incapable of swimming relying on the current to steer them and carry them to their desired destination. When a large amount of jellyfish begin to congregate in one area it is referred to as a swarm or a bloom. These swarms can contain up to hundreds of thousands of jellyfish and can be very fatal especially if it is a bloom of box jellyfish. Jellyfish are either males or females and both males and females will release eggs and sperm into the waters around them where the eggs which are unprotected will be fertilised and will grow over time into new organisms. The lifespan of a jellyfish can range from as little as a few hours up to an average of 6 months, one species of jellyfish defies these rules though and is said to be able to avoid death all together by restarting the aging process.

All jellyfish will sting their prey, it isn't always intentional, and the slightest brush up with a jellyfish will trigger the jellyfishes automatic response to protect itself and sting. The severity of a jellyfish sting can vary greatly between the species. Many times human beings will experience no affects but at times they may experience discomfort and pain. If stung by the sea wasp jellyfish you have a very large possibility of dying as they affect not only your breathing but also your heart.

The scyphozoan jellyfish is actually harvested to be eaten by human beings. The majority of these jellyfish caught for consumption are harvested in Southeast Asia. The jellyfishes are harvested and a jellyfish master will begin to process the jellyfish undergoing a process that will take anywhere from twenty to forty days to complete and consists of many phases. The jellyfish will have a white or cream color which will change to yellow or brown if it has been stored for quite some time. In china the processed jellyfish are soaked in water through the night in order to remove the salt content and then either consumed raw or cooked.

Whenever you enter the water to go swimming, no matter where you are in the world, if you aren't in a swimming pool then there is a good chance that somewhere near you there is a jellyfish happily floating around in the water just going with the flow of the current. It is important to remember that although they look quite intriguing and they look like they would be great to play with, they will sting you, the sting can be fatal, they are sea creatures that deserve our respect, it's best to leave well alone.
