MOON JELLY
Aurelia labiata

This alien-looking creature is named for its translucent, moonlike circular bell. Instead of long, trailing tentacles, moon jellies have a short, fine fringe (cilia) that sweeps food toward the mucous layer on the edge of the bell. Prey is stored in pouches until the oral arms pick it up and begin to digest it.

The coloration of a moon jelly often changes depending on its diet. If the jelly feeds extensively on crustaceans, it turns pink or lavender. An orange tint hints that a jelly’s been feeding on brine shrimp.

Scientists have studied the life cycle of this jelly extensively. They know the adult male moon jelly releases strands of sperm, which are ingested by female moon jellies. After fertilization, larvae settle on or near the seafloor and grow into polyps. Polyps alternate between feeding and reproductive stages for up to 25 years. In the reproductive phase, polyps launch buds of cloned juveniles, known as ephyrae, which grow into adult medusae.

Found worldwide in temperate and tropical waters, moon jellies feed in quiet bays and harbors. Although moon jellies have a sting, they pose little threat to humans.

Species Information
Diet
small plankton, like molluscs, crustaceans, fish eggs and other small jellies
Size
to 15 inches (38 cm) in diameter
Range
common in Monterey Bay and along the California coast, and in the waters off the East Coast, Europe, Japan and the Gulf of Mexico
Relatives
Portuguese man-of-war, hydromedusae, other siphonophores, sea anemones, coral; Family: Ulmaridae
Conservation Notes
Moon jellies are very plentiful. However, plastic bags that end up in the ocean often look like jellies to animals that depend on these drifting creatures for food. Thousands of turtles and birds die each year after swallowing indigestible wads of plastic mistaken for jellies. You can help by picking up plastic on the beach and near storm drains.
Like other jelly populations, overabundant moon jellies indicate an unbalanced ecosystem. Scientists have discovered that jellies reproduce best when the water has too many nutrients—usually the result of run-off from land—and too little oxygen.
Cool facts
Although they didn’t get to the moon, nearly 2,500 moon jelly polyps and ephyrae—two early stages in the jelly life cycle—went into orbit aboard the space shuttle Columbia in May 1991. They were part of a study on the effects of weightlessness on development of internal organs in juvenile jellies.

Hi Manyee, this is just amazing. The shapes, light and delicate fringes have great impact, the slight hint of colour is beautiful. I love the way you have two views of the same creature in this image too and the composition is great. I'm quite jealous, it's gorgeous :)

So fragile and beautifull! I love underwater photographs. Great dark BG and these creatures looking like flying neons. Superb.

This is a very special image, Manyee.

The soft translucent quality and unusual delicate shape of this subject have been captured extremely well in your composition.

Thank you for sharing it with us.

Nice picture, congratulations
