In the summer of 1961, a group of young Italian anthropologists made a clandestine journey through Spain, in order to record popular songs that supported anti-Franco resistance.

How can these creatures, which are over 98% water and have no shell, skeleton or brain, expand so rapidly? Although this is a normal stage in the life cycle of these gelatinous animals, we have to admit that blooms have become much more frequent and massive in recent decades.
