L’acquapazza

Edible seaweeds found in the Tyrrhenian Sea include Halimeda tuna, or fico d’India marino in Italian ("sea prickly pear,” so-called for its paddle-shaped leaves), and sea asparagus (genus Salicornia), named for its superficial resemblance to the terrestrial spears. The edible Sargasso seaweed (genus Sargassum) is common in the Mediterranean.
