Reasons for Jellyfish Increase in Málaga

The article explores the reasons behind the recent surge in jellyfish sightings in Málaga, Spain during August. Experts attribute this not to warmer water temperatures, but primarily to the Levante wind, which carries the Pelagia noctiluca (a highly stinging species) towards the coast.

Role of Marine Currents and Plankton

Marine currents play a crucial role in transporting jellyfish and their food source – plankton. Higher plankton concentration leads to larger jellyfish populations.

Other Jellyfish Species

Besides the Pelagia noctiluca, the article mentions two other species present in Málaga's waters: the Rhizostoma luteum ('giant jellyfish'), which has a moderate sting, and the Cotylorhiza tuberculata ('fried egg jellyfish'), which is essentially harmless.

Additional Factors

The Ministry for Ecological Transition highlights other factors influencing jellyfish presence, including weather conditions (rain, wind, currents), hydrocarbon pollution, and overfishing (reducing competition for jellyfish).

• Levante winds are the main factor driving the arrival of Pelagia noctiluca jellyfish.
• Marine currents transport jellyfish and concentrate them in plankton-rich areas.
• Other species like Rhizostoma luteum and Cotylorhiza tuberculata are also present but less problematic.
• Additional factors include weather, pollution, and overfishing.
