Does the Adriatic Sea have jellyfish?
There are around 30 species of jellyfish in the Adriatic Sea, but only a few of them can cause a really painful sting. Fortunately, the most common species – the moon jellyfish – is fairly harmless. The smaller species, such as Pelagia noctiluca, are more unpleasant. The Adriatic Sea around Dubrovnik is generally safe for swimming. You’ll spot sea urchins near rocky areas (of which there are many), so water shoes are highly recommended to avoid stepping on one. As for jellyfish, they occasionally show up but aren’t a constant concern – and stings are rare.
