Moon Light Jellyfish

Moon light Jellyfish are known to be extremely quiet eaters. They do not attack humans, perhaps a small sting but not too horrible, more like a crab bite from the waters. The moon light jellyfish can also be referred to as the Aurelia aurita species. This is a large category that may include a variety of types of jellyfishes. It is almost impossible to distinguish the moon light jellyfish from its relatives, unless the genetic material is tested scientifically.

The average moon light jellyfish is translucent and is about 30 to 40 centimetres long. It has bright gonads that originate from its stomach, they are more likely to be shaped like horse shoes. Their swimming and feeding movements are all directed solely by one single nerve within the jellyfish. Due to the limited central nerve, the moon light jellyfish has very limited movement. It is usually seen lazily drifting around the waters of the ocean.

The moon light jellyfish kills prey by stinging them with its long tentacles, of course like every other existing jellyfish does. The type of prey the hung fall under the category of organisms like protozoans, molluscs, fish, fish eggs and crustaceans. They feed on very small prey since they are very small themselves. These jellyfish are prey to many other predators as well. Specific types of birds are known to consume moon light jellyfish. Certain fish and sea turtles also feed on these tiny moon light jellyfishes.

Here's an interesting fact, humans consume moon light jellyfish as well. They are incredibly popular within the international Asian food market. Moon light jelly fish prefer temperature that is about 9 degrees Celsius to 20 degrees Celsius. They are liable to stay alive in absolutely freezing water or hot tropical waters with temperatures higher than thirty degrees Celsius.
