ResumenAn unusual bloom of the cubozoan Carybdea marsupialis occurred at some beaches located near Denia (SW Mediterranean Sea, SE Spain) during the summer of 2008. The bloom was first detected and recorded by the local Red Cross first aid services. The number of bathers stung totaled 3,330 during the three months of summer. To asses if 2008 was an exceptional year in relation to jellyfish stings, data from previous years was also analyzed and compared with the years 1996 to 2007. Densities of C. marsupialis in the area were characterized by quantitative sampling. Sampling at shallow beaches from 15 September to 21 November 2008 gave insights into cubozoan density in the area, estimated at 265.9 individuals per 100m2 as the highest value, densities never recorded previously in the Mediterranean where the species was considered to be rare. Mean density along the 17km of coastline which was sampled reached 5.4±3.8 ind/100m2. Data on size distribution is also given. During the third week of August 2009, we randomly sampled approximately 10m3 of water in three different localities to test whether C. marsupialis populations were the same as in 2008. We sampled a total of 33 organisms of C. marsupialis (5, 2 and 26 individuals respectively) showing that population may be permanently established in the area, although future sampling is needed to confirm this fact. This paper discusses possible causes of this bloom and provides guidelines for future studies
