Moon jellyfish (Aurelia aurita) or moon jelly found in open sea waters have hundreds of fine and short tentacles that are seen on the bell part, unlike the long, potent tentacles found in other jellyfish species.

Moon jellies are the least dangerous species to come in contact with humans. Moon jellies are abundant in the world with their conservation status common currently.

The world's oceans are filled with these aurelia species and live peacefully with all other species of jellyfish in the big wide waters. During summer seasons, people go out to surf and swim on the beaches more, and it usually leads to encounters with common jellyfish stings.

Before you try your luck in the open ocean, it is important to first understand the stings of moon jellyfish or other jellies.

While some jellyfish stings can be lethal, most stings you encounter from moon jellyfish are mild and can be treated with basic remedies.

The tentacles of a jellyfish have stingers and when these tentacles touch your skin when near the ocean, the stingers inject a venom that can cause red blisters. Moon jellyfishes (Aurelia aurita) are not considered types of predators as they only have a diet of small fish.

The tentacles from the edge of the bell of the moon jellyfish are the stingers. The member of the genus aurelia is considered harmless as it does not have many powerful stinging cells.

Moon jelly are also not good swimmers and will often be found on the shore of oceans.

The stinging power of a moon jelly is not strong enough to penetrate the human skin of adults and children alike, but if you do get stung, you might feel a minor stinging sensation.

A mild irritation might occur but it is not something to be scared of. It is a very familiar situation when you go for a boat ride in Florida and the Gulf of Mexico and even when you walk on the shore of the beaches near the natural habitat of the moon jellyfish.

The purple or pink flower-shaped moon jellyfish feed only on small fish and plankton and if you get stung, do not worry about the venom.

Absolutely do not pee on the site on your body because the legend of peeing on the stung area of a jellyfish curing it is actually a myth.

The quickest and the easiest way to treat a moon jellyfish sting is to rinse the area with seawater. If it still persists, mix seawater and baking soda to reduce the irritation quickly.

Moon jellies are recognized by the four circles seen through the translucent white bell. The four circles are the reproductive organs found in the bottom of the stomach area and are purple in color. You can easily spot them washed up on the coast.

The larva searches for a place to attach itself in shallow water and then finds the seafloor. As it attaches itself to the floor, the larva grows into an upside-down medusa, also called a polyp.

In the polyp stage, a moon jellyfish larva breaks off into many clones of itself that swim to different parts as medusae and then mature into moon jellyfish that reproduce sexually. You might sometimes find moon jellyfish found washed on the coast of all of the world's oceans.

A polyp can live for years at a time and create more polyps.
