During recent blooms of Pelagia noctiluca, one of the most studied jellyfish in the<br />
world, also on the basis of a two centuries time series (Goy et al., 1989), some of the<br />
listed fish species (Tab. 1; numbers 6, 8, 14, 15, 16) showed evident signs of the<br />
massive consume of P. noctiluca, having the gut coloured by the jellyfish pigments<br />
(Avian and Rottini Sandrini, 1988; Orsi Relini et al., 2010a; Garibaldi & Orsi Relini,<br />
2010). Such observation occurred by chance, in the framework of routine biological<br />
sampling (CAMPBIOL) and/or fish purchase for personal use. Having not planned<br />
such observations, we don’t know if other fish species had the same behaviour. There<br />
is a large amount of work for the next jellyfish bloom, in particular regarding<br />
specificity, if any, of jellyfish consume.<br />
