Imagine drifting through the open ocean, sunlight dappling around you, when suddenly you're surrounded by translucent, pulsating bells. You've likely encountered the Greater Moon Jelly (Aurelia labiata)! These captivating creatures, reaching up to 40cm in diameter, are mesmerizing to watch as they rhythmically pulse through the water. While their sting is generally considered mild, it's best to admire them from a respectful distance. Keep an eye out for them in the Northeast Pacific and North Atlantic, where they can sometimes gather in impressive numbers, creating a truly unforgettable underwater spectacle. Though their depth range is not fully known, they are most often seen near the surface in epipelagic zones.
The Greater Moon Jelly is identified by its large, saucer-shaped bell, typically around 28cm but sometimes reaching 40cm. Look for the distinctive horseshoe-shaped gonads (reproductive organs) that are visible through the translucent bell. These gonads can vary in color, often appearing pinkish or purple. Also, note the short, frilly oral arms hanging down from the center of the bell, which are used to capture prey.
