Experts from the Oceanography and Fishing Institute from Split send a calming message to the concerned locals and tourists
The presence of the common jellyfish, also known as the moon jellyfish, in the waters of Kaštela Bay near Split has caused concern for many swimmers. This is especially true of parents whose children play on the popular beach of Bene beneath Marjan Hill, who often forbid them from entering the sea due to smaller and larger jellyfish that are floating around.
However, the Oceanography and Fishing Institute in Split published photographs of the jellyfish on their Facebook profile with the following information: “The common jellyfish, Aurelia Aurita, is still present in Kaštela Bay. There is no fear, the jellyfish is not dangerous.”
The common jellyfish lives in large groups. The jellyfish is translucent, usually about 25–40 cm in diameter, and can be recognized by its four horseshoe-shaped gonads, easily seen through the top of the bell. It feeds by collecting medusae, plankton, and mollusks with its tentacles, and bringing them into its body for digestion. It is capable of only limited motion, and drifts with the current, even when swimming, states the Wikipedia definition.
The jellyfish are harmless to humans as their poison cannot penetrate human skin.
