I Ricci di Mare
Sea urchins are those spiky balls that you find on the sea bed or on rocky areas by the sea. In Italian, their name actually means 'hedgehog of the sea.' il riccio = the hedgehog.
In Italy, especially the south, they are collected from the sea and eaten.
They are often eaten raw, by simply cutting them open with scissors, removing unwanted bits but leaving the red parts (as seen below). The red parts are eaten, by scooping them up with a spoon or with bread.
They are most often eaten in January when they are at their fullest.
