The sea along the coast of Tuscany was invaded by hundreds jellyfish last week. Though the occurrence is rare and can be bothersome to swimmers, biologists point out that this is also a sign of cleaner waters. Two kinds of jellyfish have been spotted. The Rizostoma Pulmo, with its mushroom shape, is the most common kind and is almost harmless. But the second type, Pelagia Noctiluca, can be a bit more bothersome. With transparent tentacles that can reach a length of up to 4 metres, it is difficult to avoid its nasty sting.
Predictions are, that with the change of currents, the jellyfish will soon retreat from the coastal waters along Tuscan beaches.
