Researchers from the University of Haifa have been studying the role of sea slugs in controlling jellyfish populations along Israel's coast. Jellyfish have a complex life cycle, including a hidden polyp stage that is difficult to monitor and manage. The study explored whether local sea slugs can survive by feeding on these jellyfish polyps and if they use the stinging capsules from their prey for their own defense. The findings suggest that sea slugs may play a key role in reducing jellyfish swarms, offering a potential natural solution to the growing problem of jellyfish blooms in the region.
