The occurrence frequency and disaster category of large jellyfish has increased continuously worldwide since 1980s. The jellyfish disaster has seriously affected the offshore marine fisheries, coastal industry, coastal tourism and marine ecosystem. The governments and organizations have paid much attention to jellyfish study such as the migration mechanisms, and work on monitoring, forecasting, and warning of jellyfish disaster. In this paper, the recent progress has been reviewed on the migration mechanisms of large jellyfish, including its drifting and aggregation behavior as well as its source. Furthermore, recent work on the monitoring, forecasting, and warning of jellyfish disaster has been introduced. Several suggestions are proposed, such as the development of a three-dimensional operational monitoring system, the need for integrated studies on the migration mechanisms, and further development of improved forecasting and warning models.
