VIDEO: "Eggs for an Eye" in the Slovenian Sea?

In recent weeks, swimmers along Slovenia’s Adriatic coast have encountered unusual sightseeing, jellyfish swimming freely in the waters near Portorož. Local residents and tourists alike have reported seeing large numbers of these creatures, some describing them as resembling floating eggs. The phenomenon has sparked curiosity among beachgoers, with many taking photos of the strange formations before deciding to cool off in the sea. The species in question, known locally as “morska cvetača” or “sea bloom,” has been observed in increasing numbers around the southern coastline. Foreign tourists visiting popular beaches such as Zelenika and Kamenjak have also noted their presence, often expressing surprise at the sight. These jellyfish, scientifically identified as Cotylorhiza tuberculata, can grow up to 40 centimeters in diameter, though they commonly measure around 20 centimeters. Their distinctive appearance, featuring a flattened bell with a central ridge surrounded by a circular canal, makes them easily identifiable. Dr. Petra Burić, a researcher at the Faculty of Natural Sciences in Pula, has explained that this particular species is both unique and highly recognizable. She notes that adult specimens display a characteristic greenish-brown coloration, which sets them apart from other jellyfish species. According to her, these organisms play an essential role in the marine ecosystem, providing shelter for young fish in open waters. Despite their striking appearance, local experts have confirmed that these jellyfish pose no threat to humans. Dr. Burić emphasized that their sting is not harmful, and there is no cause for alarm upon encountering them in the water. However, she urged swimmers to avoid picking them up, as they are non-harmful and beneficial inhabitants of the Adriatic Sea. “We want to stress that this jellyfish is harmless to swimmers, so we ask everyone to refrain from collecting them,” she added. The increased sightings have raised questions among environmentalists and marine biologists. While the exact reason for the surge in population remains unclear, some speculate that changes in ocean temperature or nutrient levels could be contributing factors. In neighboring Croatia, similar reports have emerged, suggesting that the phenomenon may be part of a broader trend affecting the region’s coastal waters. Local authorities have responded by issuing advisories to beachgoers, encouraging them to observe the jellyfish from a distance rather than attempt to touch or remove them. This aligns with recommendations from marine conservation groups, who emphasize the importance of preserving natural habitats. The presence of these jellyfish, while visually striking, serves as a reminder of the delicate balance within marine ecosystems. As summer continues, further observations will be necessary to determine whether the current increase in jellyfish populations represents a temporary fluctuation or a more sustained shift. For now, visitors to Slovenian shores are advised to enjoy the scenery and keep their distance from these curious, harmless creatures.
