Do Moon Jellyfish Sting?

The basic and normal Jellyfishes that also happen to be in the highest numbers of all the Jellyfishes are also called the Moon Jellyfish. They normally do not sting human species. But they do use their tentacles to sting other prey and little fishes for food. Even if they were to sting humans accidentally, all it will do is leave a small rash as their cnidoblasts aren't powerful enough to penetrate human skin tissues, but most of the times these stings can hardly be felt at all.

Moon Jellyfish are carnivores. But since they lack the 3 basic things required for hunting under water- Brains, Teeth and Fins, they also settle down for tiny planktons called the Zooplankton. They navigate around under water using the round diametric bell, located about the venom carrying tentacles. Inside the Bell of a Moon Jellyfish are four sound pink masses called the Gonads. The Moon Jellyfishes happen to gather in large numbers all at one place. This is seen many a times on most parts of the world. They are very capable of swimming and navigating in stagnant waters, but in the mighty oceans, they happen to be full in the mercy of the waves and the underwater currents. This is the reason they occur in large numbers and we happen to see them washed ashore in most of the beaches.

The Moon Jellyfishes often breed during October and release tiny embryos into their surroundings. They don't keep coming to the water surface for air like some fishes do, instead they breathe right away through their outer layer in the water itself. The embryos which are around 1 to 2 cm long then go and attach themselves to a stagnant underwater structure and grow over there for another 12 months feeding on the surroundings. Then they slowly elongate and swim away as small jellyfishes.

Moon Jellyfishes are also know as Aurelia aurita scientifically. They are a very common sight in the Jellyfish hotspots such as Florida, Hawaii, Sussex, the Gulf Of Mexico and the shores of Great Britain to name a few, and occur in large numbers year after year. The large specimens of the Moon Jellyfishes were reported to have a 12 inch diameter bell.

Moon Jellyfishes are the best choice for people looking for pet jellyfishes for their aquarium tanks as they are not lethal to humans and have a very transparent structure. A large jellyfish aquarium is needed for them to swim around majestically. They feed heavily on micro planktons, but they also prefer brine shrimp. Care should also be taken to maintain the water temperature at around 12 to 18 degree Celsius (55 to 65 degrees Fahrenheit) as the waters they exist in the oceans happen to be in these temperatures too. To achieve this, one will have to invest in a refrigeration unit for the aquarium and an all day long power source for it too.
