In Japan and other countries in the world, jellyfish facts are that it is considered a delicacy. This is the reason for the development and growth of dried jellyfish market. Drying it is important to prevent it from rotting. If it is left wet, it will take it a little while to go bad, usually in a few hours, but when dried it can be available for many weeks.

A great jellyfish facts listing is feeding for this species is rather different from rest of the family members. They feed on small fish and planktons. However, there is no real prey of theirs as this depends on the size. They use tentacles alongside stinger cells to catch their prey. These tentacles then direct the food to the mouth before it is assimilated into the body system. The stinger cells paralyze the pray and also keep away enemies closer to the jellyfish such as human beings.

Another of the jellyfish facts is that they do not have brains the way other fishes do. Other organs absent include the heart, real eyes and bones. They, however, have some features like virtual eyes which help them in detecting obstacles. They have no brains but they can process information detected by this sight and this has always been a mystery. The nerve impulses they have only helps the jellyfish to respond to two stimuli; food and danger although these are not processed by brains.

Water content in their bodies is about 95% of other components in the system. Similarly, it is considered as the oldest marine creature for having existed since 650 million years ago. Sharks and dinosaurs came years later. Being aquatic marine creatures, jellyfish facts say that they are found virtually in all seas and oceans of the world. By living in fresh water, that species is considered untrue. A unique species called sea wasp or box jellyfish eat are responsible for death of many humans than other animals in water. The biggest one measures about 2.5 meters equivalent to eight feet.

The maximum length of a jellyfish can go up to 120 feet long. The length can further grow to be compared to the length of a half of a football playing ground. Their lifecycle is divided into three phases with the first stage being the larva. The larval phase is also referred to as planula.
