Natural HistoryLive both in solitude and in large swarms. Hardly able to move on their own, moon jellies are carried by the current. What small mobility they have comes from pulsing their bell-shaped bodies, but this motion is most effective for drawing food into their mouths. Moon jellies are considered to be an annoyance to many commercial fishermen because they can consume vast amounts of larvae of the commercial fish species. Moon jellies can indirectly cause algae blooms; as they devour large quantities of herbivorous zooplankton, the algae has less predation pressure, allowing algae blooms.
