Austrian media warns tourists to Croatia after compass jellyfish spotted

An Austrian newspaper has issued a warning to tourists planning holidays on Croatia’s coast after a compass jellyfish was spotted in shallow waters near Vrsar in Istria.

Kronen Zeitung published a video report after one of its readers filmed the jellyfish while swimming near the popular coastal area.

“Our reader-reporter certainly did not expect such an unpleasant surprise as the one that awaited her on vacation in Croatia. Instead of an idyllic and pleasant refreshment in the sea, while swimming she suddenly spotted a poisonous compass jellyfish and immediately pulled out her camera,” writes Krone.

The sighting has renewed attention on the species, which experts say has been appearing more frequently in the northern Adriatic in recent years.

The compass jellyfish is easily recognised by the distinctive dark V-shaped markings on its yellowish-brown bell, resembling the points of a compass. While visually striking, its tentacles contain stinging cells that can cause painful skin reactions.

According to experts cited by the Austrian newspaper, contact with the jellyfish can result in intense pain, burning sensations, redness and swelling. Sensitive individuals may experience stronger allergic reactions, although serious complications are uncommon.

Authorities and marine experts also stress that caution is necessary even when jellyfish appear dead on the beach.

Their stinging cells can remain active and still cause painful reactions if touched.

In the event of contact, experts advise rinsing the affected area with seawater rather than fresh water and avoiding rubbing the skin, as this can trigger additional stings.

Cooling creams may help relieve discomfort, while medical attention is recommended if symptoms become severe or an allergic reaction develops.

Compass jellyfish are native to the Atlantic Ocean and the Mediterranean Sea and are increasingly being reported in both the northern and southern Adriatic. Their peak season is typically during May and early summer, when sea users are more likely to encounter them.

Experts continue to encourage swimmers and beachgoers to avoid touching jellyfish and to report sightings to relevant authorities. The latest sighting serves as a reminder for residents and visitors alike to remain vigilant while enjoying the Adriatic during the warmer months.
