The sea moon jellyfish does not have eyes.

The sea moon jellyfish, which is beautiful and highly ornamental, is a relatively common jellyfish that often floats in swarms on the surface of the sea. Their bodies are milky white or light blue, slightly transparent, with a distinct jellyfish umbrella shaped like an inverted bowl. Four distinct stomach cavities are visible from the transparent jellyfish umbrella. Sea moon jellyfish is not without eyes, in his "umbrella" on the edge of a number of notches, each notch has an eye spot, can feel the intensity of light.

They use their tentacles to catch prey, such as jellyfish, plankton and mollusks. But the tentacles have limited movement and they will just go with the flow. Live in the Atlantic, Pacific, and Indian Oceans. Water mother bodies can be male or female. Floating wave larvae have tiny ciliated cells and can float for up to a day, then settle on a suitable substrate and transform into a hydrozoan, which splits into tiny butterfly-like larvae through a transverse fissure and grows up to become a water mother.

Reproduction Technique

1. Larval Attachment Stage: Prepare five or six flat boards and put them in the jellyfish tank, and place two small shells at the bottom of the tank to collect the larvae from the mantle of the jellyfish.

2. Formation stage of knobbed body: When you see white mantle mouth larvae attached in the jellyfish tank, you can feed the larvae of the shrimp, and the water temperature is best at 25 ℃, and the knobbed body will be formed about one month later.

3, the section of the crack stage: when the mantle mouth larvae breeding to a certain number, can be placed in the quarantine pool or glass plate shells in the giant crabs tank cooling. 20d, the mantle mouth larvae of the tentacles become shorter, the color from white to brown, which is the section of the crack. After the water temperature drops for 20-30d, the knuckleheads will split from one to five to ten.

4, the small jellyfish formation stage: from the knobbed body peeled off to become a saucer-shaped larvae, this stage of the larvae is very small, can be moved to a small aquarium rearing. In the pumping should be very careful, there can not be bubbles, only the water flow through, but the water flow should not be too strong, the degree of water flow control to not let the small jellyfish sink to the bottom of the aquarium can be. This is also the time to feed the larvae of the Toyon shrimp, and when they reach about 2cm, they can be moved to a jellyfish aquarium with a filtration system.
