Not baby octopuses (polpi), but curled octopuses (eledone cirrhosa), cousins of the big boys, common in the Mediterranean and caught when they measure 15-20cm.
A moscardino also means dormouse. Preserved in jars, then stuffed and roasted, these were a delicacy for the ancient Etruscans and Romans. In Croatia and Slovenia, they still are.
Also known as fragoline di mare.
