RESUMO
Three edible jellyfish Rhopilema hispidum, R. esculentum and Nemopilema nomurai are virulent to humans. We monitored one patient that was stung sequentially by these three species of jellyfish. The first species caused a persistent eruption, the second produced significant pruritus and the last induced only cutaneous symptoms rather than severe systemic disorders reported for its Chinese counterpart. The lesions of these jellyfish species are characteristic and common in workers harvesting medusae. There is no significant incidence of symptoms by ingesting these animals.

Olindias sambaquiensis, known as agua viva, is an endemic hydromedusa that is distributed from latitude 23 degrees to 42 degrees south in the southwestern Atlantic Ocean and is known to cause severe stings. This is the first report of the use of vinegar in disarming O sambaquiensis nematocysts and includes preliminary observations on its use in managing the stings of hydromedusae.

Multiple stages of Liriope tetraphylla caused paresthesias leading to chafing and excoriations in swimmers along the Southern Uruguayan and Northern Argentinean Atlantic coasts. These episodes appear seasonally in the summer and affect groups of bathers in shallow water (1-3 m).

Olindias sambaquiensis, Muller 1861 (Hydrozoa: Limnomedusae: Olindiidae) is a neritic jellyfish endemic in the Blanca Bay area (South of Buenos Aires, Argentina). In this paper we describe the first report of a dermatitis caused by this jellyfish in a thirty-four-year-old marine biologist who presented with an erythematous vesicular eruption after contact with Olindias sambaquiensis. Some preliminary ultramicroscopic observations on the nematocysts of this jellyfish are also reported.
