All Jellyfish

Jellyfish or jellies as they are also known as are animals which live only in the water and the waters of the earth are home to over 1500 different species of jellyfish. Just because we aren't able to see them all does not mean that they are not in fact there. Jellyfish may reside or simply frequent the waters anywhere from the shiny surface of the water right down to the dark deep depths of the ocean floor.

Jellyfish can be anywhere from as small as the pinkie finger fingernail of an adult right up to as frighteningly large as a pair of washing machines. Jellyfish can come in a variety of colors including some species which come in purples, yellows, blues, oranges and the more common colors such as white, opaque and transparent. Jellyfish are strange gelatinous marine creatures which lack a spine, brain and respiratory system. Due to this lack of a respiratory system jellyfish instead oxygenate their bodies through a process of diffusion.

The majority of jellyfish species are not capable of swimming so instead rely on the currents and the winds to steer them and assist them in travelling to their destination. A large congregation of jellyfish in one concentrated area is often referred to as a bloom of jellyfish or a swarm of jellyfish. These blooms of jellyfish can consist of hundreds of thousands of jellyfish and can prove to be fatal especially if the swarm consists of box jellyfish. Jellyfish can be either a male or a female and both genders release eggs and sperm into the water surrounding them where the eggs will then be fertilised and unprotected and they will then transform into new organisms over a period of time.

Jellyfish can live anywhere from only a measly few hours up to about an average age of six months. There is one particular species of jellyfish which defies this rule and is thought to be able to avoid death all together by restarting the aging process. All jellyfish sting their prey, this action isn't always done intentionally by the jellyfish but the slightest contact with a jellyfish will trigger the jellyfish's automatic response mechanism which is to protect itself by stinging the potential predator. Just how painful or severe a jellyfish sting will be is varied amongst the different species. There are many times where a human will not experience any effects from a jellyfish sting but it is normal for most of them to cause some discomfort and pain.

The box jellyfish of Australia is deadly and its sting is often accompanied by cardiac problems and respiratory distress if prompt medical attention is not sought after. Some jellyfish are even harvested by humans for the sole purpose of human consumption. Some places consider jellyfish to be just a daily food source where as other places in the world consider it to be a delicacy menu item. Even today there are still more jellyfish being discovered in the waters all throughout the world and no doubt there will be more yet to find.
