These days, some experts are concerned that warming oceans could trigger a surge in jellyfish populations, prompting fears of a "jellyfish armageddon" that could have major ecological and industrial implications if they end up clogging power inlets and harbours.

But others say spikes in their populations are normal and occur naturally. There's no clear answer. Even though jellyfish have thrived for millions of years, predating even the reign of dinosaurs on Earth, they remain something of a mystery. 

In the vibrant waters of South Africa, a renowned jellyfish and marine hotspot, dedicated researchers are looking to uncover the secrets of these fascinating creatures.

Scientists Verena Ras from the Universiy of Cape Town and Mark Gibbons from the University of the Western Cape explain why understanding and studying these elusive marine creatures is important for both the environment and humans: Not only are they an indicator species for global warming, they also play a crucial role  in carbon cycling and have the potential to be a sustainable food source.
