According to Antoni Grau, an official with the Balearic Islands’ fisheries directorate, the number of jellyfish reaching the Mallorcan coast has been lower this summer than at any point since 2014. This is based on reports by lifeguards and coastal cleaning vessels rather than any formal survey.
Pelagia noctiluca, commonly called the mauve stinger, purple people eater, or simply the purple jellyfish, is the most frequently sighted jellyfish around Mallorca. It lives at a depth of nearly 1,000 feet but rises to the surface at night to feed.
Scientists are unclear on what brings them to the coast, but they postulate winds and currents as the most probable cause. For this reason, experts theorize that the lack of storms this spring and summer are responsible for the decline in sightings.
Though the purple jellyfish is considered a pest to beachgoers because of its painful sting, it’s rarely dangerous.
