Some people ignore them and feel quite comfortable in the water, others prefer to avoid contact with them for various reasons (from disgust to fear). And they are right, as some of the species are a threat to health and even life - an expert zoologist will tell about them.
The main danger of an encounter with a jellyfish is not only a burn which is surely unpleasant but also that after a sting a person may develop a strong allergic reaction to toxins in her numerous stinging cells.
