Moon Jellyfish 月亮水母 at Ocean Park Hong Kong . . .

This was taken at the Grand Aquarium, Ocean Park Hong Kong. Ocean Park Hong Kong, commonly known as Ocean Park, is a marine mammal park, oceanarium, animal theme park and amusement park situated in Wong Chuk Hang and Nam Long Shan in the Southern District of Hong Kong. It is the second largest theme park in Hong Kong, following Hong Kong Disneyland.

 

There were a few cylindrical tanks exhibiting these lovely creatures. I also saw a few with 5 or 6 gonads. They glowed in suitable lighting and dark background.

 

Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly) is a widely studied species of the genus Aurelia. There are usually four horseshoe shaped gonads that are found at the top of the bell for the Moon Jellyfish. Their body is white in color and round which gives it the moon shape. That is where their name derives from. They are very transparent too so when the sun or the moon is shining on them they look just like the moon does all lit up. They have very short tentacles in terms of what other species of Jellyfish offer. When fully grown a Moon Jellyfish is typically from 25 to 40 cm wide. Due to the round look of them they are often referred to as the Saucer Jelly. They may have stripes or spots when they are younger around the middle of the bell area. Aurelia aurita and other Aurelia species feed on plankton that includes organisms such as mollusks, crustaceans, tunicate larvae, rotifers, young polychaetes, protozoans, diatoms, eggs, fish eggs, and other small organisms. Occasionally, they are also seen feeding on gelatinous zooplankton such as hydromedusae and ctenophores. (Sourced from internet)
