Although they are looked weak, jellyfish equipped with a special tool called nematocysts, or stinging cells on their tentacles. They use it to sting and to capture the prey. Beside the tentacles, the main part of the moon jellyfish is the bell. Moon jellyfish bell is about between 5 to 40 cm. The bell often has stripe or spot patterns. It is opaque or transparent.

Moon jellyfish are carnivorous animals. Their main food is small plankton called zooplankton. They also eat animal molluscs, rotifers, nematods, diatoms, larval fish, skinned larvae, crustaceans, and protozoa. During capturing the prey, nematocysts or  stinging cells play an important role. Stinging cells are capable for injecting venom. When the tentacles reach the prey, the cells will launch the venom into the prey's body. The cells are also used as defense from predators. They will extend their tentacles when predators approach them. However, few animals known to be immune of their poison like turtles sea turtles, which are also their predators.
